CISA Questions and Answers

 The most critical finding that the IS auditor should consider when reviewing processes for importing market price data from external data providers is that the quality of the data is not monitored. This is because market price data is essential for financial transactions, risk management, valuation and reporting, and any errors or inaccuracies in the data can have significant impact on the organization’s performance, reputation and compliance. The IS auditor should ensure that the organization has established quality criteria and controls for the imported data, such as validity, completeness, timeliness, consistency and accuracy, and that the data is regularly checked and verified against these criteria. The other findings are also important, but not as critical as data quality. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.7

A virtual tape library (VTL) is a disk-based backup system that emulates a tape library. It provides faster backup and recovery than traditional tape systems, and it can be integrated with data deduplication and replication technologies to enhance disaster recovery. A VTL can also be replicated to an offsite location for additional protection. A VTL is the best disaster recovery solution for an environment where data virtualization is used, because it can handle large volumes of data, support multiple backup applications, and provide consistent performance.

Onsite disk-based backup systems (A) are not the best disaster recovery solution, because they are vulnerable to the same risks as the primary data center, such as fire, flood, power outage, or sabotage. Tape-based backup systems (B) are not the best disaster recovery solution, because they are slow, prone to errors, and require manual intervention. Redundant array of independent disks (RAID) (D) is not a backup system, but a storage technology that improves performance and fault tolerance by distributing data across multiple disks. RAID does not protect against data corruption, human error, or malicious attacks.

 Ongoing monitoring of the audit activities is the most important activity to include as part of the quality assurance (QA) program requirements for an internal audit department. An IS auditor should perform regular reviews and evaluations of the audit processes, methods, standards, and outcomes to ensure that they comply with the QA program objectives and criteria. This will help to maintain and improve the quality and consistency of the audit services and deliverables. The other options are less important activities to include as part of the QA program requirements, as they may involve long-term resource planning, user satisfaction reports, or feedback from internal audit staff. References:

The greatest risk if two users have concurrent access to the same database record is data integrity. Data integrity is the property that ensures that the data is accurate, complete, consistent, and valid throughout its lifecycle. If two users have concurrent access to the same database record, they may modify or delete the data in a conflicting or inconsistent manner, resulting in data corruption, loss, or duplication. This can affect the reliability and quality of the data, and cause errors or anomalies in the database operations and functions. The IS auditor should verify that the database has adequate controls to prevent or resolve concurrent access issues, such as locking mechanisms, transaction isolation levels, concurrency control protocols, or timestamping methods. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.7

The business owner is the person or entity that has the authority and responsibility for defining the purpose and scope of the processing of personal data, as well as the expected outcomes and benefits. The business owner is also accountable for ensuring that the processing of personal data complies with the applicable laws and regulations, such as the General Data Protection Regulation (GDPR) or the Data Protection Act 2018 (DPA 2018).

One of the requirements of the GDPR and the DPA 2018 is to adhere to the principle of storage limitation, which states that personal data should be kept for no longer than is necessary for the purposes for which it is processed1. This means that the business owner should determine and justify how long they need to retain personal data, based on factors such as:

The nature and sensitivity of the personal data

The legal or contractual obligations or rights that apply to the personal data

The business or operational needs and expectations that depend on the personal data

The risks and impacts that may arise from retaining or deleting the personal data

The business owner should also establish and document the conditions and methods for the destruction of personal data, such as:

The criteria and triggers for deciding when to destroy personal data

The procedures and tools for securely erasing or anonymising personal data

The roles and responsibilities for carrying out and overseeing the destruction of personal data

The records and reports for verifying and evidencing the destruction of personal data

Therefore, retention periods and conditions for the destruction of personal data should be determined by the business owner, as they are in charge of defining and managing the processing of personal data, as well as ensuring its compliance with the law.

The greatest concern with the lack of structure for technology risk governance is C. Key decision-making entities for technology risk have not been identified. Technology risk governance is the process of establishing and maintaining the policies, roles, responsibilities, and accountabilities for managing technology risks within an organization1. Technology risk governance requires a clear organizational structure that defines who has the authority and responsibility to make decisions, set objectives, allocate resources, monitor performance, and ensure compliance for technology risk management2. Without such a structure, an organization may face the following challenges:

Lack of alignment and integration between technology and business strategies, leading to suboptimal outcomes and missed opportunities.

Lack of clarity and consistency in technology risk identification, assessment, mitigation, and reporting, leading to gaps and overlaps in risk coverage and exposure.

Lack of communication and collaboration among different stakeholders involved in technology risk management, leading to conflicts and inefficiencies.

Lack of oversight and accountability for technology risk management activities and results, leading to poor quality and reliability.

The best way to prevent data leakage from a lost mobile device is data encryption on the mobile device. Data encryption is a technique that transforms data into an unreadable format using a secret key or algorithm. Data encryption protects data from unauthorized access or disclosure in case of loss or theft of a mobile device. Complex password policy for mobile devices, triggering of remote data wipe capabilities, and awareness training for mobile device users are useful measures to enhance data security on mobile devices, but they do not prevent data leakage as effectively as data encryption. A complex password policy can be bypassed by brute force attacks or password cracking tools. Remote data wipe capabilities depend on network connectivity and device power availability. Awareness training for mobile device users can reduce human errors or negligence, but it cannot guarantee compliance or behavior change. References: CISA Review Manual (Digital Version): Chapter 5 - Information Systems Operations and Business Resilience

 The IS auditor should be most concerned about the lack of follow-up education for staff members who failed the phishing simulation test. Phishing simulation tests are designed to assess the level of awareness and susceptibility of staff members to phishing attacks, and to provide feedback and training to improve their security behavior. If staff members who failed the test do not receive follow-up education, they will not learn from their mistakes and may continue to fall victim to real phishing attacks, which could compromise the security of the organization.

The other options are less concerning for the IS auditor:

Test results were not communicated to staff members. This is not ideal, as staff members should receive feedback on their performance and learn from the test results. However, this does not necessarily mean that they did not receive any training or education on how to avoid phishing attacks.

Staff members were not notified about the test beforehand. This is a common practice for phishing simulation tests, as it mimics the real-world scenario where staff members do not know when they will receive a phishing email. The purpose of the test is to measure their spontaneous reaction and awareness, not their preparedness or compliance.

Security awareness training was not provided prior to the test. This is not a major concern, as the test can serve as a baseline measurement of the current level of awareness and susceptibility of staff members, and as a starting point for providing tailored training and education based on the test results.

The primary objective of an IS auditor when reviewing the installation of a new server is to ensure that security parameters are set in accordance with the organization’s policies. Security parameters are settingsor options that control the security level and behavior of the server, such as authentication methods, encryption algorithms, access rights, audit logs, firewall rules, or password policies7. The organization’s policies are documents that define the security goals, requirements, standards, and guidelines for the organization’s information systems. An IS auditor should verify that security parameters are set in accordance with the organization’s policies to ensure that the new server complies with the organization’s security expectations and regulations. The other options are less important or incorrect because:

A. Security parameters should not be set in accordance with the manufacturer’s standards alone, as they may not reflect the organization’s specific security needs and environment. The manufacturer’s standards are general recommendations or best practices for configuring the server’s security parameters based on common scenarios and threats. An IS auditor should compare the manufacturer’s standards with the organization’s policies and identify any gaps or conflicts that need to be resolved.

B. A detailed business case should have been formally approved prior to the purchase of a new server rather than during its installation. A business case is a document that justifies the need for a new server based on its expected benefits, costs, risks, and alternatives. A business case should be approved by senior management before initiating a project to acquire a new server.

D. The procurement project should have invited tenders from at least three different suppliers before purchasing a new server rather than during its installation. A tender is a formal offer or proposal to provide a product or service at a specified price and quality. Inviting tenders from multiple suppliers helps to ensure a fair and competitive procurement process that can result in the best value for money and quality for the organization. References: Server Security - ISACA, [Information Security Policy - ISACA], [Server Hardening - ISACA] , [Business Case - ISACA], [Tender - ISACA] , [Procurement Management - ISACA]

 The greatest concern for an IS auditor when evaluating an organization’s IT strategy and plans is that IT is not engaged in business strategic planning, as this indicates a lack of alignment between IT and business objectives, which could result in inefficient and ineffective use of IT resources and capabilities. The absence of a defined IT security policy, the nondistribution of business strategy meeting minutes, and the inadequate documentation of IT strategic planning are also issues that should be addressed by an IS auditor, but they are not as significant as IT’s noninvolvement in business strategic planning. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.1

Awalk-through of job functionsprovides direct evidence thatseparation of duties (SoD)is implemented effectively. It involves observing employees as they perform tasks to confirm that no single person has excessive privileges.

Walk-through of Job Functions (Correct Answer – D)

Confirms that duties are appropriately divided in real-world operations.

Helps verify whether security policies and controls are enforced.

Example:An auditor observes that the same person cannot create and approve financial transactions.

Review of Personnel Files (Incorrect – A)

Personnel files contain job details but do not confirm how duties are performed.

Analysis of Documented Job Descriptions (Incorrect – B)

Job descriptions may be outdated or inaccurate.

Review of Organizational Chart (Incorrect – C)

Shows reporting relationships but does not confirm SoD implementation.

Comprehensive and Detailed Explanation:

The most concerning issue in DLP implementations is when tuning has never been completed.

DLP solutions require fine-tuning to properly recognize sensitive data patterns and avoid false positives/false negatives.

If tuning is incomplete, the solution will either block legitimate business processes (too restrictive) or fail to detect actual leaks (too permissive).

Now let’s break down the options:

Option A: Server support limitations may be an issue, but DLP is primarily endpoint-focused here.

Option B: Implementing blocking mode without tuning can cause disruptions, but it is not as bad as never completing tuning.

Option D: Running in monitoring mode is acceptable in early stages of deployment (testing phase).

Therefore, never completing tuning (C) represents a fundamental control weakness and is the greatest concern.

???? ISACA Reference: CISA Review Manual 27th Edition, Domain 5, section on data leakage prevention and monitoring tools.

The answer D is correct because the greatest concern for an IS auditor with the situation of business owners being removed from the project initiation phase is that the requirements may be incomplete. The project initiation phase is the first step in starting a new project, where the project’s purpose, scope, objectives, and deliverables are defined and documented. The project initiation phase also involves identifying and engaging the key stakeholders who have an interest or influence in the project, such as sponsors, customers, users, or business owners.

Business owners are the individuals or entities who have the authority and responsibility to define the business needs and expectations for the project. They are also the primary beneficiaries of the project outcomes and benefits. Business owners play a crucial role in the project initiation phase, as they provide valuable input and feedback on the requirements and specifications of the project. Requirements are the statements that describe what the project should accomplish or deliver to meet the business needs and expectations. Requirements are essential for guiding the project planning, execution, monitoring, and closure phases.

If business owners are removed from the project initiation phase, it can result in incomplete or inaccurate requirements, which can have negative impacts on the project’s quality, scope, time, cost, and risk. Some of the possible consequences of incomplete requirements are:

Misalignment: The project may not align with the business strategy, vision, or goals, which can reduce its value or relevance.

Confusion: The project team may not have a clear understanding of what the project should achieve or deliver, which can affect their performance or productivity.

Rework: The project may need to undergo frequent changes or revisions to accommodate new or modified requirements, which can increase the time and cost of the project.

Dissatisfaction: The project may not meet the expectations or satisfaction of the business owners or other stakeholders, which can affect their acceptance or support of the project.

Failure: The project may not deliver the expected outcomes or benefits, which can affect its success or viability.

Therefore, an IS auditor should be concerned about the involvement and participation of business owners in the project initiation phase, as it affects the completeness and quality of requirements. An IS auditor should review the policies and procedures for stakeholder identification and engagement, verify that the business owners have adequate knowledge and skills to define their requirements, and test that the requirements are well-defined, documented, approved, and communicated.

 Providing security certification for a new system should include an evaluation of the configuration management practices prior to the system’s implementation. Configuration management is a process that ensures that the system’s components are identified, controlled, and tracked throughout the system’s lifecycle. Configuration management helps to maintain the security and integrity of the system by preventing unauthorized or unintended changes. End-user authorization to use the system in production is not part of security certification, but rather a post-implementation activity that grants access rights to authorized users. External audit sign-off on financial controls is not part of security certification, but rather a verification activity that ensures that the system complies with financial reporting standards. Testing of the system within the production environment is not part of securitycertification, but rather a validation activity that ensures that the system meets the functional and performance requirements. References:

Disabling USB access for storage devices is a preventive control because it is intended to stop malware introduction before it occurs. ISACA explicitly describes disabling USB access for storage devices as a preventive control that makes it harder for users to introduce threats such as viruses into the environment.

Option C is correct because the control works in advance of the event. It prevents users from connecting removable storage that could carry malicious software or facilitate unauthorized data transfer.

Option A is incorrect because corrective controls act after an incident to restore or remediate conditions. USB blocking does not restore anything after infection.

Option B is not the best answer because although administrative policy may require the control, the specific control being described functionally prevents an unwanted event. In CISA questions, the functional type is the better classification here.

Option D is incorrect because the control is not physical; it is a logical/technical measure enforced through system configuration.

Therefore, C is the best answer because disabling USB storage access is designed to prevent malware from being introduced through physical media.

References (Official ISACA):

ISACA, Specific Controls You Can Use — disabling USB access for storage devices is described as a preventive control.

ISACA Journal, Addressing Cybersecurity Vulnerabilities — preventive controls are used to reduce exposure before compromise.

Unauthorized data modifications during conversion (D) are the most critical concern because they compromise data integrity, leading to inaccurate or corrupted information in the new system. Data migration should be performed with strict controls, including validation, reconciliation, and audit trails.

Other options:

Lack of online backups (A) is a risk but not as severe as compromised data integrity. Offline backups may still exist.

Undocumented change management (B) is a process deficiency but does not directly affect data accuracy.

Manual data conversion (C) increases risk but does not automatically indicate unauthorized changes.

The most effective way to minimize downtime during system conversions is to use a parallel run. A parallel run is a method of system conversion where both the old and new systems operate simultaneously for a period of time until the new system is verified to be functioning correctly. Thisreduces the risk of errors, data loss, or system failure during conversion and allows for a smooth transition from one system to another. References: CISA Review Manual, 27th Edition, page 467

The best approach for an IS auditor to evaluate whether the IT strategy supports the organization’s vision and mission is to meet with senior management to understand the business goals and how IT can enable them. This will help the IS auditor to assess the alignment and integration of IT with the business strategy and to identify any gaps or opportunities for improvement. Reviewing ROIs, KPIs, or feedback from other departments may provide some insights, but they are not sufficient to evaluate the IT strategy. References: IS Audit and Assurance Standards, section “Standard 1201: Engagement Planning”

Data loss can occur due to various reasons, such as accidental deletion, hardware failure, malware infection, theft, or unauthorized access. Data classification procedures can help to identify and protect sensitive data, but they are not sufficient to prevent data loss. The most effective way to protect against data loss is to conduct periodic security awareness training for employees, which can educate them on the importance of data security, the best practices for data handling and storage, and the common threats and risks to data. 

Outsourcing the development of an e-banking solution when in-house technical expertise is not available can significantly reduce start-up costs. This is because the organization can avoid the expenses associated with hiring and training a full-time development team, purchasing necessary hardware and software, and maintaining the system1. While outsourcing can also potentially reduce the risk of system downtime, increase the ability to adapt the system, and provide direct oversight of risks, these benefits are not as immediate or guaranteed as the cost savings123.

Maximum Tolerable Outage (MTO) (A) defines the longest time an organization can tolerate an IT service being unavailable before significant business impact occurs. It determines business continuity planning and disaster recovery strategies.

Other options:

RPO (B) defines acceptable data loss but does not determine the total outage limit.

SDO (C) is related to service agreements but does not set the risk threshold.

AIW (D) is similar to MTO but is not as commonly used in disaster recovery planning.

Access controls for source libraries are the features of a library control software package that would protect against unauthorized updating of source code. Access controls are the mechanisms that regulate who can access, modify, or delete the source code stored in the source libraries. Source libraries are the repositories that contain the source code files and their versions. By implementing access controls for source libraries, the library controlsoftware package can prevent unauthorized or malicious users from tampering with the source code and compromising its integrity, security, or functionality1.

The other options are not as effective as access controls for source libraries in protecting against unauthorized updating of source code. Option A, required approvals at each life cycle step, is a good practice but may not be sufficient to prevent unauthorized updates if the approval process is bypassed or compromised. Option B, date and time stamping of source and object code, is a useful feature but may not prevent unauthorized updates if the date and time stamps are altered or ignored. Option D, release-to-release comparison of source code, is a helpful feature but may not prevent unauthorized updates if the comparison results are not reviewed or acted upon.

The best answer is A. To ensure the appropriate level of protection to assets.

ISACA guidance explains that asset categorization indicates the level of concern that should be given to an asset, and that identifying and classifying critical assets is done to avoid adverse effects from theft, loss, compromise, or misuse. In other words, classification tells the organization how much protection a given asset requires.

Option B may be a by-product, but alignment to standards is not the primary reason. Option C is broader than the specific purpose of classification. Option D may follow from classification, but classification is primarily about matching protection strength to asset importance and sensitivity.

The quality assurance (QA) phase is the phase where the IS auditor should first examine requirements from an in-house SDLC project that has not met user specifications. This is because the QA phase is the phase where the system is tested and verified against the user specifications and the design specifications to ensure that it meets the functional and non-functional requirements, as well as the quality standards and expectations. The QA phase involves various testing activities, such as unit testing, integration testing, system testing, acceptance testing, performance testing, security testing, etc., to identify and resolve any defects, errors, or deviations from the specifications12.

The configuration phase is not the phase where the IS auditor should first examine requirements from an in-house SDLC project that has not met user specifications. The configuration phase is the phase where the system is installed and configured on the target environment, such as hardware, software, network, etc., to prepare it for deployment and operation. The configuration phase may involve activities such as installation, customization, migration, integration, etc., to ensure that the system is compatible and interoperable with the existinginfrastructure and systems34.

The user training phase is not the phase where the IS auditor should first examine requirements from an in-house SDLC project that has not met user specifications. The user training phase is the phase where the end-users are trained and educated on how to use the system effectively and efficiently. The user training phase may involve activities such as developing training materials, conducting training sessions, providing feedback and support, etc., to ensure that the users are familiar and comfortable with the system features and functions56.

The development phase is not the phase where the IS auditor should first examine requirements from an in-house SDLC project that has not met user specifications. The development phase is the phase where the system is coded and built based on the design specifications and the user specifications. The development phase may involve activities such as programming, debugging, documenting, etc., to create a working prototype or a final product of the system

 This is because privacy regulations are laws or rules that protect the personal information of individuals from unauthorized access, use, disclosure, or transfer by third parties. Payroll audit documentation may contain sensitive and confidential data, such as employee names, salaries, benefits, taxes, deductions, and bank accounts. If the audit management application is hosted by a third party in a different country, the organization may need to comply with the privacy regulations of both its own country and the host country, as well as any international or regional agreements or frameworks that apply. Privacy regulations may impose various requirements and obligations on the organization, such as obtaining consent from the data subjects, implementing appropriate security measures, notifying data breaches, and ensuring data quality and accuracy. Privacy regulations may also grant various rights to the data subjects, such as accessing, correcting, deleting, or transferring their data. Failing to comply with privacy regulations may expose the organization to significant risks and consequences, such as legal actions, fines, sanctions, reputational damage, or loss of trust.

Some examples of privacy regulations affecting the organization are:

The General Data Protection Regulation (GDPR), which is a comprehensive and strict privacy regulation that applies to anyorganization that processes personal data of individuals in the European Union (EU) or offers goods or services to them, regardless ofwhere the organization or the data is located1.

The California Consumer Privacy Act (CCPA), which is a broad and influential privacy regulation that applies to any organization that collectspersonal information of California residentsand meets certain thresholds of revenue, data volume, or data sharing2.

The Health Insurance Portability and Accountability Act (HIPAA), which is a sector-specific privacy regulation that applies to any organization that handles protected health information(PHI) of individuals in the United States, such as health care providers, health plans, or health care clearinghouses3.

Therefore, before using an audit management application hosted by a third party in a different country, the internal audit team should conduct a thorough assessment of the privacy regulations affecting the organization and ensure that they have adequate policies, procedures, and controls in place to comply with them.

When an employee exploits avulnerability, the most appropriate audit is aforensic audit, as it focuses oninvestigating and documenting security incidentsfor legal or disciplinary action.

Option A (Incorrect):Acompliance auditensures adherence to policies but does not investigate incidents in detail.

Option B (Incorrect):Application security testinghelps identify vulnerabilities but does not addressemployee misuse.

Option C (Correct):Aforensic auditgathersdigital evidence, determines how the exploit occurred, and ensures legal compliance in the investigation.

Option D (Incorrect):Penetration testingidentifies weaknesses but does notanalyze past incidents.

The key audit concern at data input is integrity—ensuring accuracy, validity, and completeness. Without integrity, outputs cannot be trusted. Availability and resilience are operational concerns, while normalization is a design technique. Integrity remains the top security and audit focus.

References (ISACA): ISACA Audit and Assurance Standards – Information Criteria (Effectiveness, Efficiency, Integrity, Availability).

The primary difference between a Business Continuity Plan (BCP) and a Disaster Recovery Plan (DRP) lies in their timeframe for activation and overall scope.

BCP (Business Continuity Plan):

Focuses on ensuring that critical business processes continue operating during and after a disruption.

It includes strategies for maintaining operations (e.g., alternative work locations, manual procedures, supplier dependencies).

Activated immediately when a disruption occurs to keep the business running.

DRP (Disaster Recovery Plan):

Primarily focuses on the recovery of IT systems and infrastructure after a disruption.

It includes steps for restoring data, servers, and applications to bring IT operations back to normal.

Activated after the disaster event to restore normal IT operations.

The timeframe for activation is the key difference because:

BCP is implemented immediately to ensure business continuity.

DRP is implemented after the disaster to restore IT operations.

A. The annual testing requirements → Both BCP and DRP require regular testing, so this is not the key differentiator.

B. The focus on system recovery → Only DRP focuses on system recovery, but the BCP covers more than just IT. The key difference is still the timeframe.

D. The involvement of senior management → Senior management is involved in both plans, so this is not the primary distinction.

Comprehensive and Detailed Explanation:

The greatest concern is if the vendor is excluded from the organization’s third-party due diligence process. Without proper due diligence, the organization has no assurance that the vendor meets minimum security and privacy requirements, exposing PII to significant risk.

Option A: External-facing services carry risk but can be mitigated by proper controls.

Option B: Lack of dedicated privacy staff may increase risk, but controls may still exist.

Option C: Fourth-party hosting adds risk but is acceptable if included in due diligence.

Option D: Correct — exclusion from due diligence represents a fundamental breakdown in vendor risk management.

???? ISACA Reference: CISA Review Manual 27th Edition, Domain 5, section on third-party/vendor risk management and data privacy.

A monitored mantrap at entrance and exit points would be the most effective compensating control in this scenario. A mantrap is a physical security access control system comprising a small space having two sets of interlockingdoors such that the first set of doors must close before the second set opens. By implementing a monitored mantrap, unauthorized access can be prevented and it can ensure that all individuals are logged when they enter and exit the server room12.

Thespeed at which security threats are mitigatedis akey indicatorof an organization ' srisk management effectiveness.

Option A (Correct):Response time to security threatsmeasures how efficiently security teams detect, analyze, and mitigate risks, providingclear insight into security operations.

Option B (Incorrect):The number of security controls auditeddoes not indicatehow well risk is being managed, only that reviews are taking place.

Option C (Incorrect):Log analysis speedis useful, but it does notdirectly measure risk mitigation effectiveness.

Option D (Incorrect):Risk register entriesindicate known risks but do not provide insight intohow well those risks are managed.

The best way to determine whether IT investments are meeting business objectives is to compare the realized return on investment (ROI) versus the projected ROI (Option B). This approach measures actual performance against planned expectations.

ISACA CISA Reference: The ISACA IT Governance framework emphasizes performance measurement through ROI analysis, ensuring IT investments align with strategic objectives.

Risk Implication: If actual ROI is lower than projected, this may indicate ineffective investment decisions, poor execution, or misalignment with business goals.

Alternative Choices:

Option A: Break-even analysis only determines when an investment recoups its costs but does not measure performance against business objectives.

Option C: Budgeted versus actual spend assesses financial discipline but does not indicate business impact.

Option D: Industry average ROI provides benchmarking but does not assess internal goal achievement.

The approach adopted by management in this scenario is risk avoidance. Risk avoidance is the elimination of a risk by discontinuing or not undertaking an activity that poses a threat to the organization3. By moving data center operations to another facility on higher ground, management is avoiding the potential flooding risk that could disrupt or damage the data center. Risk transfer, risk acceptance and risk reduction are other possible approaches for dealing with risks, but they do not apply in this case. References:

 Backup procedures for an organization’s critical data are considered to be corrective controls, as they are designed to restore normal operations after a disruption or failure. Corrective controls aim to minimize the impact of an incident and prevent recurrence. Directive, detective and compensating controls are not related to backup procedures. Directive controls are intended to guide or instruct users to follow policies and procedures. Detective controls are intended to identify and report incidents or violations. Compensating controls are intended to mitigate the risk of a missing or ineffective primary control. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.11

The primary objective of value delivery in reference to IT governance is to optimize investments. Value delivery is one of the five focus areas of IT governance that aims to ensure that IT delivers expected benefits to stakeholders and enables business value creation. Value delivery involves aligning IT investments with business objectives and strategies, managing IT performance and benefits realization, optimizing IT costs and risks, and enhancing IT innovation and agility. Value delivery helps to maximize the return on investment (ROI) and value for money (VFM) of IT resources and capabilities. References:

The correct answer is A. Overwriting multiple times. Overwriting is a method of securely erasing data from a hard disk by replacing the existing data with random or meaningless data, making it difficult or impossible to recover the original data1. Overwriting multiple times, also known as multiple-pass overwriting, is a more effective way of disposing of sensitive data than overwriting once, as it reduces the possibility of residual traces of data that could be recovered by advanced techniques2. Overwriting multiple times can be done by using specialized software tools that follow certain standards or algorithms, such as the US Department of Defense’s DoD 5220.22-M or the Gutmann method3.

 The chain of custody has not been documented is a finding that should be of greatest concern for an IS auditor reviewing a forensic analysis process of an organization that has suffered a cyber attack. The chain of custody is a record of who handled, accessed, or modified the evidence during a forensic investigation. Documenting the chain of custody is essential to preserve the integrity, authenticity, and admissibility of the evidence in a court of law. The other options are less concerning findings that may not affect the validity or reliability of the forensic analysis process. References:

 An external assessment of network vulnerability is a process of identifying and evaluating the weaknesses and risks that affect the security and availability of a network froman outsider’s perspective. The most important factor to verify during this process is the completeness of network asset inventory, which is a list of all the devices, systems, and software that are connected to or part of the network. A complete and accurate network asset inventory can help identify the scope and boundaries of the network, the potential attack vectors and entry points, the critical assets and dependencies, and the existing security controls and gaps. Without a complete network asset inventory, an external assessment of network vulnerability may miss some important assets or vulnerabilities, leading to inaccurate or incomplete results and recommendations.

The primary purpose of documenting audit objectives when preparing for an engagement is to identify areas with relatively high probability of material problems. Audit objectives are statements that describe what the audit intends to accomplish or verify during the engagement. Audit objectives help the IS auditor to focus on the key areas of risk or concern, to design appropriate audit procedures and tests, and to evaluate audit evidence and results. By documenting audit objectives, the IS auditor can identify areas with relatively high probability of material problems that may affect the achievement of audit goals or business objectives. Addressing the overall risk associated with the activity under review, ensuring maximum use of audit resources during the engagement and prioritizing and scheduling auditee meetings are also purposes of documenting audit objectives, but they are not as primary as identifying areas with high probability of material problems. References:

Ransomwareis a type of malicious software that encrypts the victim’s data and demands a ransom for its decryption1. Ransomware attacks can cause significant damage to an organization’s operations, reputation, andfinances1. Therefore, it is important to mitigate the impact of ransomware attacks by implementing effective prevention and recovery strategies.

One of the best ways to mitigate the impact of ransomware attacks is to back up data frequently12345. Data backups are copies of the organization’s data that are stored in a separate location or medium, such as an external harddrive, cloud storage, or tape2. Data backupscan help the organization restore its data in case of a ransomware attack, without paying the ransom or losing valuable information2. Data backups shouldbe performed regularly, preferably daily or weekly, depending on the criticality and volume of the data2. Data backups should also be tested periodically to ensure their integrity and usability2.

The other options are not as effective as backing up data frequently in mitigating the impact of ransomware attacks. Invoking the disaster recovery plan (DRP) is a reactive measure that can help the organization resume its operations after a ransomware attack, but it does not prevent or reduce the damage caused by the attack3. Paying the ransom is not a recommended option, as it does not guarantee the decryption of the data or the deletion of the stolen data by the attackers. Paying the ransom also encourages further attacks and funds criminal activities14. Requiring password changes for administrative accounts is a good security practice, but it is not sufficient to prevent or recover from ransomware attacks. Ransomware attacks can exploit other vulnerabilities, such as phishing emails, outdated software, or weak network security15.

 During an audit of a multinational bank’s disposal process, an IS auditor should be most concerned about backup media being disposed before the end of the retention period. This is because backup media contain sensitive and critical data that may be required for business continuity, legal compliance, or forensic purposes. Disposing backup media prematurely may result in data loss, unavailability, or corruption, which may have severe consequences for the bank’s reputation, operations, and security. Backup media not being reviewed before disposal, degaussing being used instead of physical shredding, and hardware not being destroyed by a certified vendor are also findings that may pose some risks to the bank’s disposal process, but they are not as critical as backup media being disposed before the end of the retention period. References: ISACA CISA Review Manual 27th Edition, page 302.

Network segmentation is the best security measure to reduce the risk of propagation when a cyberattack occurs, because it divides the network into smaller subnetworks that are isolated from each other and have different access controls and security policies. This limits the spread of malicious traffic and prevents attackers from accessing sensitive data or systems in other segments. Aperimeter firewall, a data loss prevention (DLP) system, and a web application firewall are also useful security measures, but they do not prevent propagation within the network as effectively as network segmentation does. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.3

 The best way to ensure that a proper cutoff has been established to reinstate transactions and records to their condition just prior to a computer system failure is to use a database management system (DBMS) to dynamically back-out partially processed transactions. A DBMS is a software system that manages the creation, manipulation, retrieval, and security of data stored in a database. A DBMS can provide features such as transaction management, concurrency control, recovery management, and integrity management. A DBMS can dynamically back-out partially processed transactions by using mechanisms such as rollback segments, undo logs, or write-ahead logs. These mechanisms allow the DBMS to restore the database to a consistent state before the failure occurred. References:

 The main purpose of an information security management system (ISMS) is to reduce the frequency and impact of information security incidents. An ISMS is a systematic approach to managing information security risks, policies, procedures, and controls within an organization. An ISMS aims to ensure the confidentiality, integrity, and availability of information assets, as well as to comply with relevant laws and regulations. The other options are not the main purpose of an ISMS, but rather some of its possible benefits or components. References:

Thebest protectionfor a stolen laptop isfull disk encryption, which prevents unauthorized accesseven if the device is lost.

Option A (Incorrect):Remote wipe capabilitiesare useful, but theyrequire an internet connectionto function, which is not always available when a device is stolen.

Option B (Correct):Full disk encryption (FDE)ensures that data remainsunreadablewithout the correct decryption key,even if the hard drive is removed.

Option C (Incorrect):User awarenessis helpful, but itdoes not physically securedata on a lost device.

Option D (Incorrect):Password-protected filescan be bypassed by copying them to another system, making them an inadequate security measure.

 The primary reason to perform a risk assessment is to determine the current risk profile of the organization, which is the level of risk exposure and the likelihood and impact of potential threats. This will help the organization to identify and prioritize the risks that need to be addressed and to align the risk management strategy with the business objectives. A risk assessment may also help to achieve compliance, support the BIA, and allocate budget, but these are not the primary reasons. References: ISACA Glossary of Terms, section “risk assessment”

 The IS auditor’s primary focus when evaluating an organization’s offsite storage facility should be the adequacy of physical and environmental controls. Physical and environmental controls are essential to protect the offsite storage facility from unauthorized access, theft, fire, water damage, pests or other hazards that could compromise the integrity and availability of backup media. Shared facilities is something that the IS auditor should consider when evaluating the offsite storage facility, but it is not the primary focus. Results of business continuity plan (BCP) test or retention policy and period are things that the IS auditor should review when evaluating the organization’s BCP or backup strategy, not the offsite storage facility itself. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 388

The best compensating control is performing a bank reconciliation. Duplicate payments are a financial processing error that results in overpayment or duplicate disbursement. ISACA materials explicitly cite duplicate payments as an example of information errors that create cost risk. A bank reconciliation is the best compensating detective control among the choices because it helps identify duplicate disbursements by comparing recorded payments with actual bank activity.

Option B is correct because reconciliation is the control most likely to detect that a payment was processed twice. Once identified, management can investigate and recover the erroneous payment.

Option A is not the best answer because hash totals are generally used to verify data integrity of fields, not to compensate for duplicate payment processing.

Option D is also not the best answer because control totals can help identify completeness or reasonableness during batch processing, but they are less directly effective at detecting duplicate disbursements already posted through an online payment process.

Option C is weak because manual receipting of payments does not directly address duplication of outbound payments.

Therefore, B is the best answer because bank reconciliation is the most effective compensating control among the options for detecting duplicate payment errors. The exact match to this exam-style question is based on standard CISA control reasoning, with ISACA support that duplicate payments are a recognized cost-risk example.

References (Official ISACA):

ISACA Journal, A Framework for Estimating ROI of Automated Internal Controls — cites duplicate payments and overpayments as examples of cost risk caused by information errors.

Segregation of duties (SOD) is a core internal control and an essential component of an effective risk management strategy. SOD emphasizes sharing the responsibilities of key business processesby distributing the discrete functions of these processes to multiple people and departments, helping to reduce the risk of possible errors and fraud1.

SOD is especially important in IT security, where granting excessive system access to one person or group can lead to harmful consequences, such as data breaches, identity theft, or bypassing security controls2. SOD breaks IT-related tasks into four separate function categories: authorization, custody, recordkeeping, and reconciliation1. Ideally, no one person or department holds responsibility in multiple categories.

In a role-based environment, where access privileges are granted based on predefined roles, it is important to ensure that the roles are designed and assigned in a way that supports SOD. For example, the person who develops an application should not also be the one who tests it, deploys it, or maintains it.

Therefore, an application developer should not be assigned the roles of IT operator, system administration, or database administration, as these roles may conflict with their development role and create opportunities for misuse or abuse of the system. The only role that may be assigned to an application developer without violating SOD is emergency support, which is a temporary role that allows the developer to access the system in case of a critical issue that requires immediate resolution3. However, even this role should be granted with caution and monitored closely to ensure compliance with SOD policies.

The impact if corrective actions are not taken is the most important factor to consider when scheduling follow-up audits. An IS auditor should prioritize the follow-up audits based on the risk and potential consequences of not addressing the audit findings and recommendations. The other options are less important factors that may affect the timing and scope of the follow-up audits, but not their necessity or urgency. References:

The management decision that presents the greatest risk associated with data leakage is not providing security awareness training to staff. This is because staff are often the weakest link in the information security chain, and they may unintentionally or maliciously leak sensitive data through various channels, such as email, social media, cloud storage, or removable media. Security awareness training is essential to educate staff on the importance of protecting data, the policies and procedures for handling data, and the best practices for preventing and reporting data leakage incidents. Not requiring desktops to be encrypted, allowing staff to work remotely, and not updating security policies in the past year are also management decisions that may increase the risk of data leakage, but they are not as significant as not providing security awareness training to staff. Encryption, remote work, and security policies are technical or administrative controls that can be implemented or enforced by management, but they cannot fully prevent or mitigate human errors or malicious actions by staff. References: CISA Review Manual (Digital Version), [ISACA Privacy Principles and Program Management Guide]

 The primary reason for an IS auditor to conduct post-implementation reviews is to determine whether project objectives in the business case have been achieved. A post-implementation review is an audit activity that evaluates whether a project has delivered its expected outcomes or benefits in accordance with its objectives, scope, budget, and schedule. A business case is a document that defines and justifies the need, value, and feasibility of a project. A post-implementation review can help assess whether project objectives in the business case have been achieved by comparing actual results with planned expectations and identifying any gaps or deviations. The other options are not primary reasons for conducting post-implementation reviews, as they do not measure whether project objectives in the business case have been achieved. Ensuring key stakeholder sign-off has been obtained is a project closure activity that confirms that all project deliverables have been completed and accepted by key stakeholders, but it does not evaluate whether project objectives in the business case have been achieved. Aligning project objectives with business needs is a project initiation activity that ensures that the project is aligned with the organization’s strategy, goals, and priorities, but it does not evaluate whether project objectives in the business case have been achieved. Documenting lessons learned to improve future project delivery is a project learning activity that captures and shares the knowledge, experience, and feedback gained from the project, but it does not evaluate whether project objectives in the business case have been achieved. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.3

Generalized audit software is a type of computer-assisted audit technique (CAAT) that allows the IS auditor to perform various audit tasks on the data stored in different file formats and databases1. Generalized audit software can help the IS auditor to select a sample for testing that includes the 80 largest client balances and a random sample of the rest, by using functions such as sorting, filtering, stratifying, and randomizing the data23. Generalized audit software can also help the IS auditor to perform other audit procedures on the sample, such as verifying the accuracy, completeness, and validity of the data4.

The primary advantage of a decentralized database architecture over a centralized one is that it reduces the concentration of risk in a single location or single service point. Because data and processing are distributed, the effect of a single outage or denial of service event is generally reduced compared with a centralized architecture, where one core point of failure can disrupt the whole environment.

Option A is therefore the best answer. Decentralization improves resilience by avoiding total dependency on one central database or service node. In audit and risk terms, this lowers the impact of certain availability attacks or failures by distributing exposure.

Option B is incorrect because real-time synchronization over public networks is usually more difficult, not easier, in decentralized environments. Distributed synchronization introduces latency, consistency, and network management challenges.

Option C is incorrect because transaction consistency is generally harder to maintain in decentralized systems. Distributed databases often trade some degree of simplicity or immediacy of consistency for resilience, scalability, or local autonomy.

Option D is incorrect because uniform security policy enforcement is usually easier in centralized architectures, where governance and administration can be applied from a single control point.

So the correct answer is A, because the main architectural benefit of decentralization in this context is reduced single-point failure risk and reduced impact from centralized service disruption.

 The greatest impact as a result of the ongoing deterioration of a detective control is an increased number of false negatives in security logs. A detective control is a control that monitors and identifies any deviations or anomalies from the expected or normal behavior or performance of a system or process. A security log is a record of events or activities that occur within a system or network, such as user access, file changes, system errors, or security incidents. A false negative is a situation where a security log fails to detect or report an actual deviation or anomaly that has occurred, such as an unauthorized access, a malicious modification, or a security breach. An increased number of false negatives in security logs can have a significant impact on the organization’s security posture and risk management, because it can prevent timely detection and response to security threats, compromise the accuracy and reliability of security monitoring and reporting, and undermine the accountability and auditability of user actions and transactions. The other options are not as impactful as anincreased number of false negatives in security logs, because they either do not affect the detection capability of a detective control, or they have less severe consequences for security management. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.1

Comprehensive and Detailed Explanation:

A tabletop exercise is the most cost-effective method to test the BCP because it simulates scenarios and walks through responses without disrupting operations.

Stress test (A): More resource-intensive and may disrupt services.

Full operational test (C): Provides the highest assurance but is costly and disruptive.

Post-implementation review (D): Evaluates after actual incidents, not proactive.

 The most important thing to include in forensic data collection and preservation procedures is preserving data integrity. Data integrity is the property that ensures that data is accurate, complete, and consistent throughout its lifecycle. Preserving data integrity is essential for forensic data collection and preservation procedures because it ensures that the data can be used as valid and reliable evidence in legal proceedings or investigations. Preserving data integrity can be achieved by using methods such as hashing, checksums, digital signatures, write blockers, tamper-evident seals, or timestamps. The other options are not as important as preserving data integrity in forensic data collection and preservation procedures, as they do not affect the validity or reliability of the data. Assuring the physical security of devices is a security measure that protects devices from unauthorized access, theft, damage, or destruction, but it does not ensure that the data on the devices is accurate, complete, and consistent. Maintaining chain of custody is a documentation technique that records and tracks the handling and transfer of devices or data among different parties involved in forensic activities, but it does not ensure that the data on the devices is accurate, complete, and consistent. Determining tools to be used is a planning activity that selects and prepares the appropriate tools for forensic data collection and preservation procedures, but it does not ensure that the data collected and preserved by the tools is accurate, complete, and consistent. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.4

Unauthorized changes can be moved into production is the best concern that is addressed by securing production source libraries. Production source libraries contain the source code of programs that are used in the production environment. Securing production source libraries means implementing access controls, change management procedures, and audit trails to prevent unauthorized or improper changes to the source code that could affect the functionality, performance, or security of the production programs. The other options are less relevant concerns that may not be directly addressed by securing production source libraries, but rather by other controls such as program approval, version control, or change testing. References:

Capability maturity models (CMMs) are frameworks that help organizations assess and improve their processes in various domains, such as software development, project management, service delivery, and cybersecurity1. CMMs define different levels of process maturity, from initial to optimized, and describe the characteristics and best practices of each level. By using CMMs, organizations can benchmark their current processes against a common standard, identify gaps and weaknesses, and implement improvement actions to achieve higher levels of process maturity2. CMMs can also help organizations align their processes with their strategic goals, measure their performance, and increase their efficiency, quality, and customer satisfaction3.

Therefore, the use of CMMs would best enhance a process improvement program, as they provide a systematic and structured approach to evaluate and improve processes based on proven principles and practices. Option C is the correct answer.

Option A is not correct because model-based design notations are graphical or textual languages that help designers specify, visualize, and document the structure and behavior of systems4. While they can be useful for designing and communicating complex systems, they do not directly address the process improvement aspect of a program.

Option B is not correct because balanced scorecard is a strategic management tool that helps organizations translate their vision and mission into measurable objectives and indicators. While it can be useful for monitoring and evaluating the performance of a program, it does not provide specific guidance on how to improve processes.

Option D is not correct because project management methodologies are sets of principles and practices that help organizations plan, execute, and control projects. While they can be useful for managing the scope, schedule, cost, quality, and risk of a program, they do not focus on the process improvement aspect of a program.

Enterprise architecture (EA) governance ensures that IT and business alignment is maintained and that new processes and technologies integrate well with existing structures.

Option A (Correct):The primary purpose of EA governance is to ensure that new technologies, processes, and systems align and harmonize with existing architecture to maintain operational efficiency and consistency.

Option B (Incorrect):While adaptability to emerging technology trends is important, EA governance focuses more on structure, consistency, and compliance rather than just adaptability.

Option C (Incorrect):Compliance with regulations is crucial, but it is just one component of governance. EA governance has a broader scope, including strategic alignment and process integration.

Option D (Incorrect):Ensuring ROI is an important financial consideration, but it is not themainobjective of EA governance.

Substantive testing © provides the best evidence of the validity and integrity of logs in an organization’s security information and event management (SIEM) system, because it is a type of audit testing that directly examines the accuracy, completeness, and reliability of the data and transactions recorded in the logs. Substantive testing can involve various methods, such as re-performance, inspection, observation, inquiry, or computer-assisted audit techniques (CAATs), to verify the existence, occurrence, valuation, ownership, presentation, and disclosure of the log data1. Substantive testing canalso detect any errors, omissions, alterations, or manipulations of the log data that may indicate fraud or misstatement2.

Compliance testing (A) is not the best evidence of the validity and integrity of logs in an organization’s SIEM system, because it is a type of audit testing that evaluates the design and effectiveness of the internal controls that are implemented to ensure compliance with laws, regulations, policies, and procedures. Compliance testing can involve various methods, such as walkthroughs, questionnaires, checklists, or flowcharts, to assess the adequacy, consistency, and operation of the internal controls1. Compliance testing can provide assurance that the log data are generated and processed in accordance with the established rules and standards, but it does not directly verify the accuracy and reliability of the log data itself2.

Stop-or-go sampling (B) is not a type of audit testing, but a type of sampling technique that auditors use to select a sample from a population for testing. Stop-or-go sampling is a sequential sampling technique that allows auditors to stop testing before reaching the predetermined sample size if the results are satisfactory or conclusive. Stop-or-go sampling can reduce the audit cost and time by avoiding unnecessary testing, but it can also increase the sampling risk and uncertainty by relying on a smaller sample3. Stop-or-go sampling does not provide any evidence of the validity and integrity of logs in an organization’s SIEM system by itself; it depends on the type and quality of the audit tests performed on the selected sample.

Variable sampling (D) is not a type of audit testing, but a type of sampling technique that auditors use to estimate a numerical characteristic of a population for testing. Variable sampling is a statistical sampling technique that allows auditors to measure the amount or rate of error or deviation in a population by using quantitative methods. Variable sampling can provide precise and objective results by using mathematical formulas and confidence intervals4. Variable sampling does not provide any evidence of the validity and integrity of logs in an organization’s SIEM system by itself; it depends on the type and quality of the audit tests performed on the selected sample.

 An organization outsourced its IS functions. To meet its responsibility for disaster recovery, the organization should coordinate disaster recovery administration with the outsourcing vendor. This is because the organization remains accountable for ensuring the continuity and availability of its IS functions, even if they are outsourced to a third party. The organization should establish clear roles and responsibilities, communication channels, testing procedures, and escalation processes with the outsourcing vendor for disaster recovery purposes. The organization should not discontinue maintenance of the disaster recovery plan (DRP), as it still needs to have a documented and updated plan for restoring its IS functions in case of a disaster. The organization should not delegate evaluation of disaster recovery to a third party or internal audit, as it still needs to monitor and review the performance and compliance of the outsourcing vendor with respect to disaster recovery objectives and standards. References: CISA Review Manual (Digital Version), [ISACA Auditing Standards]

The main purpose of an IDS is to detect and report malicious or suspicious activity on a network or a host. If an IDS fails to identify actual attacks, it means that the IDS is not functioning properly or effectively, and it exposes the organization to serious security risks and potential damage. This is the most concerning scenario for an IS auditor, as it indicates a major deficiency in the IDS performance and configuration.

A balanced scorecard is a framework that translates the IT strategy into measurable objectives, indicators, targets, and initiatives across four perspectives: financial, customer, internal process, and learning and growth. A balanced scorecard helps to monitor and evaluate how well the IT function is delivering value to the organization, achieving its strategic goals, and improving its capabilities and competencies. The other options are not the primary uses of a balanced scorecard, because they either focus on specific aspects of IT rather than the overall performance, or they are not directly related to the IT strategy.

An IT service desk is a function that provides technical support and assistance to the users of an organization’s IT systems and services. An IT service desk typically handles issues such as software installation, hardware troubleshooting, network connectivity, password reset, system configuration,and user training. An IT service desk aims to ensure that the IT systems and services are available, reliable, secure, and efficient for the users.

One of the best indications that there are potential problems within an organization’s IT service desk function is an excessive backlog of user requests. A backlog is a list of user requests that have not been resolved or completed by the IT service desk within a specified time frame. An excessive backlog means that the IT service desk is unable to meet the demand or expectations of the users, and that the users are experiencing delays, dissatisfaction, or frustration with the IT service desk.

An excessive backlog of user requests can indicate various problems within the IT service desk function, such as:

Insufficient staff, resources, or capacity to handle the volume or complexity of user requests

Ineffective processes, procedures, or tools for managing, prioritizing, or resolving user requests

Lack of skills, knowledge, or training among the IT service desk staff to deal with different types of user requests

Poor communication, collaboration, or coordination among the IT service desk staff or with other IT functions or stakeholders

Low quality, performance, or security of the IT systems or services that cause frequent or recurring user issues

Therefore, an excessive backlog of user requests is the best indication that there are potential problems within an organization’s IT service desk function.

 The best evidence of an IT strategy correction’s effectiveness is the synchronization of IT activities with corporate objectives. The IT strategy correction is a process of reviewing and adjusting the IT strategy to ensure that it aligns with and supports the corporate strategy and objectives. The synchronization of IT activities with corporate objectives means that the IT activities are consistent with and contribute to the achievement of the corporate goals and vision. The IS auditor can measure and evaluate the IT strategy correction’s effectiveness by comparing the IT activities with the corporate objectives, and assessing whether they are aligned, integrated, and coordinated. The other options are not as good evidence of an IT strategy correction’s effectiveness, because they either do not reflect the alignment of IT and business, or they are inputs or outputs of the IT strategycorrection process rather than outcomes or results. References: CISA Review Manual (Digital Version)1, Chapter 1, Section 1.2.1

Consolidating multiple applications on asingle serverincreases the risk that aserver outagewillimpact multiple applicationssimultaneously.

More Applications Affected by Outage (Correct Answer – B)

Asingle point of failurecoulddisrupt multiple services.

Example:If aconsolidated server crashes, all hosted applications gooffline.

Higher OS License Fees (Incorrect – A)

License feesmay increase, butdowntime risk is a greater concern.

Simplified Asset Management (Incorrect – C)

True, butdoes not outweigh the availability risk.

Fewer Vulnerability Scans (Incorrect – D)

Reducing the number of serversdoes not reduce security risks.

The most reliable evidence is evidence obtained directly by the auditor through independent performance of procedures. ISACA guidance notes that higher-assurance audit work is achieved when evidence is produced directly by auditors, or at least strictly under their control, rather than being supplied by the entity being audited.

Option D is correct because independently performing manual procedures gives the auditor direct control over the evidence-gathering process and reduces reliance on the auditee or control owner. In audit theory and in ISACA-aligned practice, evidence obtained directly by the auditor is generally more reliable than evidence merely provided by the auditee.

Option A is strong evidence because it comes from an independent third party, but it is still inspected rather than generated directly by the auditor. It is generally very reliable, but not as strong as auditor-generated evidence through independent reperformance.

Option B is less reliable because system-generated evidence provided by a control owner still depends on the completeness and integrity of what was selected and presented by the auditee.

Option C is the least reliable among the plausible choices because critical data received from an auditee is subject to the greatest dependence on management representation and auditee-controlled extraction.

Therefore, D is the best answer because evidence generated through procedures performed independently by the auditor is the most reliable.

A comprehensive asset inventory is the most important factor for the successful establishment of a security vulnerability management program. A security vulnerability management program is a systematic process of identifying, assessing, prioritizing, and remediating vulnerabilities in the organization’s IT environment1. A comprehensive asset inventory is a complete and accurate record of all the hardware, software, and network components that the organization owns or uses2. A comprehensive asset inventory helps the organization to:

Know what assets are in scope for vulnerability scanning and assessment3.

Identify the vulnerabilities that affect each asset and their severity level4.

Prioritize the remediation of vulnerabilities based on the criticality and value of each asset.

Track the status and progress of vulnerability remediation for each asset.

Measure the effectiveness and maturity of the vulnerability management program.

A robust tabletop exercise plan is a simulated scenario that tests the organization’s preparedness and response capabilities for a potential cyberattack or incident. A tabletop exercise plan is useful for validating and improving the organization’s incident response plan, but it is not essential for establishing a security vulnerability management program.

A tested incident response plan is a documented process that defines the roles, responsibilities, and actions of the organization’s personnel in the event of a cyberattack or incident. A tested incident response plan is important for minimizing the impact and restoring normal operations after a security breach, but it is not critical for establishing a security vulnerability management program.

An approved patching policy is a set of rules and guidelines that governs how the organization applies patches and updates to its IT systems and applications. An approved patching policy is a key component of the remediation phase of the vulnerability management program, but it is not sufficient for establishing a security vulnerability management program.

Transaction tagging is a technique by which transactions are marked with unique identifiers or headers and traced through the system using agents or sensors at each processing point1. Transaction tagging allows for continuous monitoring and analysis of transaction processing in a high-volume, real-time system by providing visibility into the performance, availability, and reliability of each transaction and its components1. Transaction tagging can also help to identify and isolate errors, bottlenecks, anomalies, and security issues in the system1.

An IS auditor reviewing the threat assessment for a data center would be most concerned if all identified threats relate to external entities. This indicates that the threat assessment is incomplete and biased, as it ignores the potential threats from internal sources, such as employees, contractors, vendors, or authorized visitors. Internal threats can pose significant risks to the data center, as they may have access to sensitive information, systems, or facilities, and may exploit their privileges for malicious or fraudulent purposes. According to a study by IBM, 60% of cyberattacks in 2015 were carried out by insiders1

Some of the identified threats are unlikely to occur is not a cause for concern, as it shows that the threat assessment is comprehensive and realistic, and considers all possible scenarios, regardless of their probability. A threat assessment should not exclude any potential threats based on subjective judgments or assumptions, as they may still have a high impact if they materialize.

The exercise was completed by local management is not a cause for concern, as it shows that the threat assessment is conducted by the people who are most familiar with the data center’s operations, environment, and risks. Local management may have more relevant and accurate information and insights than external parties, and may be more invested in the outcome of the threat assessment.

Neighboring organizations’ operations have been included is not a cause for concern, as it shows that the threat assessment is holistic and contextual, and considers the interdependencies and influences of external factors on the data center’s security. Neighboring organizations’ operations may pose direct or indirect threats to the data center, such as physical damage, network interference, or shared vulnerabilities.

According to the CISA - Certified Information Systems Auditor Study Guide1, the correct answer to your question is A. Encrypt the disk drive. This is because encryption is a logical security measure that can protect data even if the physical device is stolen or lost. Encryption makes thedata unreadable and inaccessible without the proper key or password. The other options are not as effective as encryption in this scenario. Two-factor authentication is a user authentication method that requires two pieces of evidence to verify the user’s identity, such as a password and a code sent to a phone. However, this does not prevent unauthorized access to the data if the laptop is already logged in or if the attacker can bypass the authentication. Enhancing physical security is a preventive measure that can reduce the risk of theft, but it does not guarantee that theft will not occur or that the data will be safe if it does. Requiring the use of cable locks is another preventive measure that can deter thieves, but it can also be easily cut or removed by a determined attacker.

The best way to determine whether a test of a disaster recovery plan (DRP) was successful is to analyze whether predetermined test objectives were met. Test objectives are specific, measurable, achievable, relevant, and time-bound (SMART) goals that define what the test aims to accomplish and how it will be evaluated. Test objectives should be aligned with the DRP objectives and scope, and should cover aspects such as recovery time objectives (RTOs), recovery point objectives (RPOs), critical business functions, roles and responsibilities, communication channels, backup systems, and contingency procedures. By comparing the actual test results with the expected test objectives, the IS auditor can measure the effectiveness and efficiency of the DRP and identify any gaps or weaknesses that need to be addressed. 

 Capacity management is a process that ensures that the IT resources of an organization are sufficient to meet the current and future demands of the business. Capacity management enables organizations to identify the extent to which components need to be upgraded, by monitoring and analyzing the performance, utilization, and availability of the IT components, such as servers, networks, storage, applications, etc., and identifying any bottlenecks, gaps, or risks that may affect the service level agreements (SLAs) or quality of service (QoS). Capacity management also helps organizations to plan and optimize the use of IT resources, by forecasting the future demand and growth of the business, and aligning the IT capacity with the business needs and objectives. Forecasting technology trends is a possible outcome of capacity management, but it is not its main purpose. Establishing the capacity of network communication links is a part of capacity management, but it is not its main goal. Determining business transaction volumes is an input for capacity management, but it is not its main objective.

The most important aspect of an incident response management program is the ability to detect incidents in a timely and accurate manner. Without effective detection, the organization cannot respond to incidents, mitigate their impact, or prevent their recurrence. The alerting tools and incident responseteam are responsible for monitoring the IT environment, identifying anomalies or threats, and notifying the appropriate stakeholders.

The first step is to identify at-risk assets. Before an organization can assess impact, estimate damage, or evaluate likelihood, it must first determine which assets are exposed to the zero-day vulnerability. ISACA risk guidance emphasizes asset identification and security categorization as foundational steps in risk assessment. In other words, you cannot meaningfully assess risk until you know what systems, applications, or services are affected.

Option A is correct because scoping the exposure comes first. Once at-risk assets are identified, the organization can prioritize remediation and then evaluate impact and likelihood in a focused way. ISACA’s vulnerability and risk-related material supports risk-based prioritization built on asset visibility and understanding which systems are exposed.

Option B is not first because impact assessment depends on knowing which assets are vulnerable and how critical they are. Without that scope, impact analysis is incomplete.

Option C is also not first. Likelihood matters in risk analysis, but it comes after identifying the vulnerable environment and relevant exposure. ISACA’s risk discussions place likelihood estimation after identifying assets, threats, and vulnerabilities.

Option D is similar to impact assessment and likewise depends on first knowing which assets are in scope. Estimating damage without scoping exposure would be premature.

Therefore, A is the best answer because identifying the affected assets is the necessary first step in managing the impact of a newly discovered zero-day vulnerability.

The most important factor when planning a network audit is to identify the existing nodes on the network. Nodes are devices or systems that are connected to the network and can communicate with each other. Nodes can include servers, workstations, routers, switches, firewalls, printers, scanners, cameras, etc. Identifying the existing nodes on the network will help the auditor to determine the scope, objectives, and methodology of the audit. It will also help the auditor to assess the network topology, architecture, performance, security, and compliance. References:

CISA Questions, Answers and Explanations Database

The best course of action for a security administrator who is called in the middle of the night by the on-call programmer who needs access to the live system is to give the programmer an emergency ID for temporary access and review the activity. This is because:

Requiring that a change request be completed and approved may delay the resolution of the problem and cause further damage or disruption to the system or business operations. A change request is a formal document that describes the proposed change, its rationale, impact, benefits, risks, costs, and approval process. A change request is usually required for planned or scheduled changes, not for emergency or urgent changes.

Giving the programmer read-only access to investigate the problem may not be sufficient or effective, as the programmer may need to perform actions or tests that require write or execute permissions. Read-only access means that the user can only view or copy data or files, but cannot modify or delete them.

Reviewing activity logs the following day and investigating any suspicious activity may not prevent or detect any unauthorized or malicious actions by the programmer in real time. Activity logs are records of events and actions that occur within a system or network. Activity logs can provide evidence and accountability for system activities, but they are not proactive or preventive controls.

Therefore, giving the programmer an emergency ID for temporary access and reviewing the activity is the best course of action, as it allows the programmer to access the live system and resolve the problem quickly, while also ensuring that the security administrator can monitor and verify the programmer’s activity and revoke the access when it is no longer needed. An emergency ID is a temporary account that grants a user elevated privileges or access to a system or resource for a specific purpose and duration. An emergency ID should be:

Created and authorized by a security administrator or manager

Assigned to a specific user and purpose

Limited in scope and time

Logged and audited

Revoked and deleted after use

Some of the best practices for emergency access to live systems are12:

Establish clear policies and procedures for requesting, approving, granting, monitoring, reviewing, and revoking emergency access

Define criteria and scenarios for emergency access, such as severity, impact, urgency, and risk

Implement controls to prevent unauthorized or unnecessary use of emergency access, such as multifactor authentication, approval workflows, alerts, notifications, and time restrictions

Implement controls to track and audit emergency access activities, such as logging, reporting, analysis, and investigation

Implement controls to ensure accountability and responsibility for emergency access users, such as attestation, justification, documentation, and feedback

A single point of failure is a component or system that, if it fails, will cause the entire system to stop functioning. In virtual environments, the hypervisor is the software layer that enables multiple virtual machines to run on a single physical host. If the hypervisor is compromised, corrupted, or unavailable, all the virtual machines running on that host will be affected. This can result in data loss, downtime, or security breaches.

Virtualization: What are the security risks?

What Is a Hypervisor? (Definition, Types, Risks)

The best recommendation is to place an intrusion detection system (IDS) between the firewall and the Internet. An IDS is a device or software that monitors network traffic for malicious activity and alerts the network administrator or takes preventive action. By placing an IDS between the firewall and the Internet, the IS auditor can enhance the security of the network perimeter and detect any attack attempts that the firewall was unable to recognize.

The other options are not as effective as placing an IDS between the firewall and the Internet:

Placing an IDS between the firewall and the organization’s web server would not protect the web server from external attacks that bypass the firewall. The web server should be placed in a demilitarized zone (DMZ), which is a separate network segment that isolates public-facing servers from the internal network.

Placing an IDS between the firewall and the demilitarized zone (DMZ) would not protect the DMZ from external attacks that bypass the firewall. The DMZ should be protected by twofirewalls, one facing the Internet and one facing the internal network, with an IDS monitoring both sides of each firewall.

Placing an IDS between the firewall and the organization’s network would not protect the organization’s network from external attacks that bypass the firewall. The organization’s network should be protected by a firewall that blocks unauthorized traffic from entering or leaving the network, with an IDS monitoring both sides of the firewall.

The finding that should be of greatest concern to an IS auditor assessing the risk associated with end-user computing (EUC) in an organization is the lack of defined criteria for EUC applications. EUC applications are applications that are developed and maintained by end-users, rather than by IT professionals, to support their business functions and processes. Examples of EUC applications include spreadsheets, databases, reports, and scripts. The lack of defined criteria for EUC applications means that the organization does not have clear and consistent standards or guidelines to identify, classify, and manage EUC applications. This can lead to various risks, such as:

Inaccurate or unreliable data and results from EUC applications that are not validated, verified, or tested

Unauthorized or inappropriate access or use of EUC applications that are not secured, controlled, or monitored

Inconsistent or incompatible data and results from EUC applications that are not integrated, documented, or updated

Loss or corruption of data and results from EUC applications that are not backed up, recovered, or archived

Therefore, the IS auditor should be most concerned about the lack of defined criteria for EUC applications, as it can affect the quality, integrity, and availability of the EUC applications and the data they produce.

Insufficient processes to track ownership of each EUC application is a finding that should be of concern to an IS auditor assessing the risk associated with EUC in an organization, but it is not the greatest concern. The ownership of an EUC application refers to the person or group who is responsible for creating, maintaining, and using the EUC application. Insufficient processes to track ownership of each EUC application means that the organization does not have adequate mechanisms orrecords to identify and communicate who owns each EUC application. This can lead to risks, such as:

Lack of accountability or ownership for the quality and accuracy of the EUC application and its data

Lack of support or maintenance for the EUC application when the owner leaves or changes roles

Lack of awareness or training for the users of the EUC application on its purpose and functionality

However, these risks are less severe than those caused by the lack of defined criteria for EUC applications.

Insufficient processes to test for version control is a finding that should be of concern to an IS auditor assessing the risk associated with EUC in an organization, but it is not the greatest concern. Version control is a process that tracks and manages the changes made to an EUC application over time. Insufficient processes to test for version control means that the organization does not have adequate procedures or tools to ensure that the changes made to an EUC application are authorized, documented, and tested. This can lead to risks, such as:

Errors or inconsistencies in the data and results from different versions of the EUC application

Conflicts or confusion among the users of the EUC application on which version is current or correct

Loss or overwrite of data and results from previous versions of the EUC application

However, these risks are less severe than those caused by the lack of defined criteria for EUC applications.

Lack of awareness training for EUC users is a finding that should be of concern to an IS auditor assessing the risk associated with EUC in an organization, but it is not the greatest concern. Awareness training for EUC users is a process that educates and informs the users of the EUC applications on their roles, responsibilities, and risks. Lack of awareness training for EUC users means that the organization does not have adequate programs or materials to raise the knowledge and skills of the users on how to use and manage the EUC applications effectively and securely. This can lead to risks, such as:

Misuse or abuse of the EUC applications by users who are not aware of their impact or implications

Non-compliance or violation of policies or regulations by users who are not aware of their requirements or expectations

Dissatisfaction or frustration among users who are not aware of their benefits or limitations

However, these risks are less severe than those caused by the lack of defined criteria for EUC applications.

 A distributed security administration system is a system that allows different administrators to manage the security of different parts of the network or organization. This can provide more flexibility, scalability, and efficiency than a centralized system, where one administrator is responsible for the entire security. However, a distributed security administration system also presents some potential challenges and risks, such as:

Inconsistency and conflict among different security policies and standards

Lack of coordination and communication among different administrators

Difficulty in monitoring and auditing the overall security status and performance

Increased complexity and cost of security management and maintenance

Therefore, the greatest potential concern for implementing a distributed security administration system is that the security procedures may be inadequate to support the change. Security procedures are the rules and guidelines that define how security is implemented and enforced in an organization. They include policies, standards, processes, roles, responsibilities, controls, and metrics. Security procedures should be aligned with the business objectives, risks, and requirements of the organization, as well as the best practices and regulations in the industry. Security procedures should also be reviewed and updated regularly to reflect the changes in the environment, technology, and threats.

If the security procedures are not adequate to support the change from a centralized to a distributed security administration system, the organization may face increased security risks, such as unauthorized access, data breaches, compliance violations, reputation damage, and financial losses. Therefore, it is essential to ensure that the security procedures are revised and adapted to suit the new system, and that they are communicated and enforced effectively across the organization.

The IS auditor’s best course of action if they suspect an organization’s computer may have been used to commit a crime is to contact the incident response team to conduct an investigation. The incident response team is a group of experts who are responsible for responding to security incidents, such as data breaches, ransomware attacks, or cybercrimes. The incident response team can help to preserve and collect digital evidence, determine the scope and impact of the incident, contain and eradicate the threat, and restore normal operations. The IS auditor should not examine the computer themselves, as they may inadvertently alter or destroy potential evidence, or compromise the chain of custody. The IS auditor should also not notify local law enforcement before further investigation, as this may escalate the situation unnecessarily or interfere with the internal investigation process. The IS auditor should advise management of the crime after the investigation, or as soon as possible if there is an imminent risk or legal obligation to do so.

If an IS audit reveals that an organization is not proactively addressing known vulnerabilities, the IS auditor should recommend that the organization assess the security risks to the business first, as this would help to prioritize the vulnerabilities based on their impact and likelihood, and determine the appropriate mitigation strategies. Verifying the disaster recovery plan (DRP) has been tested, ensuring the intrusion prevention system (IPS) is effective, and confirming the incident response team understands the issue are important steps, but they are not as urgent as assessing the security risks to the business. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.6

Before sending backup drives to an offsite storage facility, the most important thing to do is to encrypt the drive with strong protection standards. This is because encryption ensures effective security where information cannot be intercepted and used to harm the organization or its customers. Encryption also protects the data from unauthorized access, modification, or deletion in case the drive is lost, stolen, or damaged during transit or storage. Encryption of backup drives is especially important for public safety organizations that handle sensitive or personally identifiable information, such as medical records, criminal records, or emergency communications12.

Recent third-party IS audit reports would be most helpful in determining the effectiveness of the IT governance framework of the target company. IT governance is a framework that defines the roles, responsibilities, and processes for aligning IT strategy with business strategy. A third-party IS audit is an independent and objective examination of an organization’s IT governance framework by an external auditor. Recent third-party IS audit reports can provide reliable and unbiased evidence of the strengths, weaknesses, and maturity of the IT governance framework of the target company. The other options are not as helpful as recent third-party IS audit reports, as they may not be as comprehensive, accurate, or current as external audits. References: CISA Review Manual, 27th Edition, page 94

Periodic recertification of users ensures that only authorized individuals retain access to cloud services and helps identify and revoke access for users who no longer require it. This is a critical control for maintaining security and compliance in a cloud environment.

Classifying Cloud Services (Option A):This is foundational but does not verify ongoing user access.

Centrally Managing Users (Option B):While useful for consistency, it does not assess whether access rights are still valid.

Ensuring Cloud Process Resilience (Option C):This focuses on operational continuity rather than access control.

Periodic recertification aligns with governance practices to ensure access rights remain appropriate over time.

Stratified mean per unit sampling is a method of audit sampling that divides the population into subgroups (strata) based on some characteristic, such as monetary value, and then selects a sample from each stratum using mean per unit sampling. Mean per unit sampling is a method of audit sampling that estimates the total value of a population by multiplying the average value of the sample items by the number of items in the population. Stratified mean per unit sampling is suitable for populations that have a high variability or a skewed distribution, such as the bank accounts in this question. By stratifying the population, the auditor can reduce the sampling error and increase the precision of the estimate.

Difference estimation sampling (option A) is not the best sampling approach for these accounts. Difference estimation sampling is a method of audit sampling that estimates the total error or misstatement in a population by multiplying the average difference between the book value and the audited value of the sample items by the number of items in the population. Difference estimation sampling is suitable for populations that have a low variability and a symmetrical distribution, which is not the case for the bank accounts in this question.

Customer unit sampling (option C) is not a sampling approach, but a type of monetary unit sampling. Monetary unit sampling is a method of audit sampling that selects sample items based on their monetary value, rather than their physical units. Customer unit sampling is a variation of monetary unit sampling that treats each customer account as a single unit, regardless of how many transactions or balances it contains. Customer unit sampling may be appropriate for testing existence or occurrence assertions, but not for estimating total values.

Unstratified mean per unit sampling (option D) is not the best sampling approach for these accounts. Unstratified mean per unit sampling is a method of audit sampling that applies mean per unit sampling to the entire population without dividing it into subgroups. Unstratified mean per unit sampling may result in a larger sample size and a lower precision than stratified mean per unit sampling, especially for populations that have a high variability or a skewed distribution, such as the bank accounts in this question.

Therefore, option B is the correct answer.

The primary area of focus when an organization decides to outsource technical support for its external customers is to align service level agreements (SLAs) with current needs. SLAs are contracts that define the scope, quality, and expectations of the services provided by the vendor, as well as the remedies or penalties for non-compliance. SLAs are essential for ensuring that the outsourced technical support meets the customer’s requirements and satisfaction, as well as the organization’s objectives andstandards. By aligning SLAs with current needs, the organization can specify the key performance indicators (KPIs), metrics, and targets that reflect the desired outcomes and value of the technical support. This can also help to monitor and evaluate the vendor’s performance, identify gaps or issues, and implement corrective actions or improvements.

A key performance indicator (KPI) is a quantifiable measure of performance over time for a specific objective1. KPIs help organizations and teams track their progress and achievements towards their strategic goals. To be useful, a KPI must have a target value, which is the desired level of performance or outcome that the organization or team aims to achieve. A target value provides a clear direction and a benchmark for measuring success or failure. Without a target value, a KPI is meaningless, as it does not indicate whether the performance is good or bad, or how far or close the organization or team is from reaching their objective.

A compliance gap analysis is a detailed review of an organization’s current state of compliance against a specific regulation or standard. It helps identify the areas and controls that are not meeting the requirements, assess their risk levels, and determine the corrective actions that can be taken to achieve compliance12. A compliance gap analysis is the most useful tool for an IS auditor to review when auditing against a new regulation, as it provides a clear and comprehensive picture of the compliance status, gaps, and remediation plan of the organization.

Mirroring (Option B) is the best choice for applications requiring a short Recovery Point Objective (RPO) because it provides real-time replication of data, ensuring minimal data loss.

ISACA CISA Reference: Data replication strategies in disaster recovery planning emphasize mirroring for high-availability systems.

Risk Implication: If mirroring is not implemented for critical systems, significant data loss may occur in the event of a failure.

Alternative Choices:

Option A: Snapshots capture data at specific points in time, leading to potential data loss.

Option C: Log shipping has delays due to batch processing.

Option D: Backups are periodic and not suitable for short RPO needs.

 Information security governance is the subset of enterprise governance that provides strategic direction, ensures that objectives are achieved, manages risk appropriately, uses organizational resources responsibly, and monitors the success or failure of the enterprise security program. Information security governance is essential for ensuring that an organization’s information assets are protected from internal and external threats, and that the organization complies with relevant laws and standards.

Demonstrated support from which of the following roles in an organization has the most influence over information security governance? The answer is C, the board of directors. The board of directors is the highest governing body of an organization, responsible for overseeing its strategic direction, performance, and accountability. The board of directors sets the tone at the top for information security governance by:

Establishing a clear vision, mission, and values for information security

Approving and reviewing information security policies and standards

Allocating sufficient resources and budget for information security

Appointing and empowering a chief information security officer (CISO) or equivalent role

Holding management accountable for information security performance and compliance

Communicating and promoting information security awareness and culture

The board of directors has the most influence over information security governance because it has the ultimate authority and responsibility for ensuring that information security is aligned with the organization’s business objectives, risks, and stakeholder expectations.

The best control to mitigate attacks that redirect Internet traffic to an unauthorized website is to perform domain name system (DNS) server security hardening. DNS servers are responsible for resolving domain names into IP addresses, and they are often targeted by attackers who want to manipulate or spoof DNS records to redirect usersto malicious websites4. By applying security best practices to DNS servers, such as encrypting DNS traffic, implementing DNSSEC, restricting access and updating patches, the organization can reduce the risk of DNS hijacking attacks. A network-based firewall, user security awareness training and a strong password policy are also important controls, but they are not as effective as DNS server security hardening in preventing this specific type of attack. References:

 The best detective control for a job scheduling process involving data transmission is job failure alerts that are automatically generated and routed to support personnel. Job failure alerts are notifications that indicate when a scheduled job or task fails to execute or complete successfully, such as due to errors, interruptions, or delays. Job failure alerts can help detect and correct any issues or anomalies in the job scheduling process involving data transmission by informing and alerting the support personnel who can investigate and resolve the problem. The other options are not as effective as job failure alerts in detecting issues or anomalies in the job scheduling process involving data transmission, as they do not provide timely or specific information or feedback. Metrics denoting the volume of monthly job failures are reported and reviewed by senior management is a reporting technique that can help measure and improve the performance and reliability of the job scheduling process, but it does not provide immediate or detailed information on individual job failures. Jobs are scheduled to be completed daily and data is transmitted using a Secure File Transfer Protocol (SFTP) is a preventive control that can help ensure the timeliness and security of the job scheduling process involving data transmission, but it does not detect any issues or anomalies that may occur during the process. Jobs are scheduled and a log of this activity is retained for subsequent review is a logging technique that can help record and track the status and results of the job scheduling process involving data transmission, but it does not provide real-time or proactive information on job failures. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.2

A Disaster Recovery as a Service (DRaaS) provider is responsible for system recovery procedures, including restoring systems and services in a disaster scenario. This is the core functionality of DRaaS.

Stakeholder Communications (Option B):This is typically managed internally by the organization to ensure alignment with its crisis management plan.

Validation of Recovered Data (Option C):The organization must verify data integrity to meet business requirements.

Maintaining Currency of Data (Option D):While DRaaS may handle data backups, the organization retains responsibility for ensuring the relevance of the data being backed up.

The greatest concern is whether the increased incident resolution time will adversely affect the organization’s business operations and whether that impact was properly assessed before the contract change. In ISACA terms, service arrangements should be aligned with business needs and service objectives. If a contract change weakens incident response commitments, the key audit concern is not simply the wording of the SLA, but whether management evaluated the resulting business impact. ISACA guidance notes that support agreements and SLAs should be aligned with internal service expectations and business requirements.

Option A is correct because incident resolution times directly affect availability, continuity, user support, and operational resilience. If the contract now permits slower restoration or resolution, the organization may be exposed to longer outages or degraded services. The central risk is whether management made that trade-off knowingly after analyzing the impact on critical business processes. This is the most important concern from an audit and governance perspective.

Option B is not the best answer because noncompliance with IT security policy could be serious, but the question specifically highlights a change in incident resolution time. Unless there is evidence of an actual policy violation, the more direct concern is operational impact on the business.

Option C is also not the greatest concern. In practice, if the contract terms changed, the SLA may need revision or alignment, but that is more of a documentation and governance symptom. The deeper issue is whether the revised service commitments are acceptable to the business. ISACA guidance stresses alignment of support agreements and SLAs with organizational needs.

Option D is the weakest answer because considering alternative cost-reduction methods is a management decision, not the primary audit concern. Auditors focus on risk and control implications, not whether management explored every possible commercial option.

Therefore, A is the best answer because the most significant issue is whether the organization evaluated the impact of slower incident resolution on business processes before accepting the lower-cost contract.

In a bare metal or native virtualization, the hypervisor runs without a host operating system. A hypervisor, also known as a virtual machine monitor or VMM, is a type of virtualization software that supports the creation and management of virtual machines (VMs) by separating a computer’s software from its hardware. A bare metal hypervisor, also called a Type I or Native hypervisor, is virtualization software that runs onhost machine hardware directly, without requiring an underlying operating system12. This means that the bare metal hypervisor is the host or the operating system (OS) of the hardware1.

A guest operating system is an operating system that runs inside a virtual machine, on top of the hypervisor. A bare metal hypervisor can run multiple guest operating systems simultaneously, each with its own applications and resources. A guest operating system is not required for a bare metal hypervisor to run, but it is necessary for running applications on the virtual machine13.

Applications are software programs that perform specific tasks or functions for users. Applications can run on either the host operating system or the guest operating system, depending on the type of virtualization. In a bare metal virtualization, applications can run on the guest operating system, but not on the host operating system, since there is no host operating system. However, applications are not essential for a bare metal hypervisor to run, as they are only used by the users of the virtual machines

Prior to a follow-up engagement, if an IS auditor learns that management has decided to accept a level of residual risk related to an audit finding without remediation, the IS auditor should report the issue to IS audit management. This is because IS audit management is responsible for ensuring that audit findings are properly communicated and resolved. Accepting management’s decision and continuing the follow-up would not address the IS auditor’s concern. Reporting the disagreement to the board or executive management would be premature and inappropriate without consulting IS audit management first. References: CISA Review Manual (Digital Version), Chapter 1, Section 1.6

The best answer is D. Feasibility study.

ISACA guidance notes that, in projects, an auditor reviews the feasibility of projects based on resources, time, and other factors, and evaluates whether projects are aligned with the organization’s strategic goals. That is exactly the stage where internal audit’s advisory involvement is most appropriate during development of the business case.

Option A, B, and C occur later in the system development lifecycle and are more operational or project-delivery focused. The question is specifically about the development of a business case, and feasibility analysis is the phase most directly tied to whether the initiative is practical, justified, and aligned with business goals.

 The IS auditor’s best course of action when reviewing the use of an outsourcer for disposal of storage media is to determine exposure to the business. Storage media, such as hard disks, tapes, flash drives, or CDs, may contain sensitive or confidential information that needs to be protected from unauthorized access, disclosure, or misuse. The IS auditor should verify that the outsourcer has a process that appropriately sanitizes the media before disposal, such as wiping, degaussing, shredding, or incinerating, and that the process is effective and compliant with the organization’s policies and standards. The IS auditor should also assess the potential impact and risk to the business if the storage media is not properly sanitized or disposed of, such as data breaches, reputational damage, legal or regulatory penalties, or loss of competitive advantage. The other options are not the best course of action, because they either do not address the root cause of the problem,or they are reactive rather than proactive measures. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.7

 The answer C is correct because preventive maintenance is outsourced to multiple vendors without requiring nondisclosure agreements (NDAs) would be of greatest concern to an IS auditor reviewing on-site preventive maintenance for an organization’s business-critical server hardware. This is because outsourcing preventive maintenance to multiple vendors without NDAs exposes the organization to the risk of unauthorized access, disclosure, or modification of sensitive data and information stored on the servers. NDAs are legal contracts that bind the vendors to protect the confidentiality and security of the data and information they access or handle during the preventive maintenance. Without NDAs, the vendors may not have any obligation or incentive to safeguard the data and information, and they may misuse, leak, or compromise them for malicious or commercial purposes. This could result in financial losses, reputational damage, legal liabilities, or regulatory penalties for the organization.

The other options are not as concerning as option C. Preventive maintenance costs exceed the business allocated budget (option A) is a financial issue that may affect the profitability or efficiency of the organization, but it does not directly impact the security or availability of the server hardware. Preventive maintenance has not been approved by the information system (option B) is a procedural issue that may indicate a lack of coordination or communication between the IT department and the business units, but it does not necessarily affect the quality or effectiveness of the preventive maintenance. The preventive maintenance schedule is based on mean time between failures (MTBF) parameters (option D) is a technical issue that may influence the frequency or timing of the preventive maintenance, but it does not imply any risk or deficiency in the preventive maintenance itself.

The best evidence to determine whether transactions have been executed by authorized employees is audit trails. Audit trails are secure records that catalog events or procedures to provide support documentation. They are used to authenticate security and operational actions, mitigate challenges, or provide proof of compliance and operational integrity2. Audit trails can track and trace the following information related to transactions:

Who initiated, approved, modified, or deleted a transaction

When a transaction occurred (date and time)

Where a transaction took place (location or device)

What type of transaction was performed (action or operation)

Why a transaction was executed (purpose or reason)

By analyzing audit trails, an IS auditor can verify whether transactions have been executed by authorized employees or not. Audit trails can also identify any unauthorized, fraudulent, or erroneous transactions that may have occurred. Audit trails can also help to resolve any disputes or discrepancies that may arise from transactions.

Shadow IT often arises when approved software does not meet user requirements (Option D), leading employees to seek alternative solutions.

ISACA CISA Reference: IT governance frameworks stress the need for user-centric IT policies to mitigate shadow IT risks.

Risk Implication: Shadow IT introduces security vulnerabilities, compliance risks, and potential data breaches.

The statement that BEST demonstrates alignment with data classification standards related to the protection of information assets is D. All information assets will be assigned a clearly defined level to facilitate proper employee handling. Data classification involves categorizing information assets based on their sensitivity, importance, and usage. Assigning clearly defined levels (such as public, internal, confidential, etc.) to information assets ensures that appropriate security controls are applied based on their classification. By doing so, organizations can manage access, encryption, and other protective measures effectively12.

The completeness of the vulnerability scanning process depends on the accuracy and currency of the organization’s systems inventory, which is a list of all the hardware and software assets that are owned or used by the organization. A complete and up-to-date systems inventory can help ensure that all the systems are identified and scanned for vulnerabilities, and that no system is missed or overlooked. Vulnerability scanning results are reported to the CISO is a good practice for ensuring accountability and visibility of the vulnerability management process, but it is not the most important thing to verify when determining the completeness of the vulnerability scanning process, as reporting does not guarantee that all the systems are scanned. The organization is using a cloud-hosted scanning tool for identification of vulnerabilities is a possible option for conducting vulnerability scanning, but it is not the most important thing to verify when determining the completeness of the vulnerability scanning process, as the type of scanning tool does not affect the scope or coverage of the scanning. Access to the vulnerability scanning tool is periodically reviewed is a critical control for ensuring the security and integrity of the vulnerability scanning tool, but it is not the most important thing to verify when determining the completeness of the vulnerability scanning process, as access review does not ensure that all the systems are scanned. 

In the event of a disaster where the data center is no longer available, the first step should be to activate the call tree1. A call tree is a layered hierarchical communication model used to notify specific individuals of an event and coordinate recovery efforts1. This ensures that all relevant parties are informed about the situation and can begin executing their parts of the disaster recovery plan1.

The best approach for determining the overall IT risk appetite of an organization when business units use different methods for managing IT risks is to prioritize the organization’s IT risk scenarios. IT risk appetite is the amount and type of IT risk that an organization is willing to accept in pursuit of its objectives. IT risk scenarios are hypothetical situations that describe the potential impact of IT risk events on the organization’s objectives, processes, and resources. By prioritizing the organization’s IT risk scenarios, the IS auditor can identify the most significant IT risks that affect the organization as a whole, and align them with the organization’s strategic goals, values, and culture. Prioritizing the organization’s IT risk scenarios can also help to communicate and monitor the IT risk appetite across the organization, and facilitate consistent and informed decision making. The other approaches (A, B and D) are not effective for determining the overall IT risk appetite of an organization, as they do not consider the impact and likelihood of IT risks on the organization’s objectives, nor do they account for the diversity and complexity of IT risks across different business units. References: CISA Review Manual (Digital Version), Chapter 2: Governance and Management of Information Technology, Section 2.3: Information Technology Risk Management

Granting access on a need-to-know basis ensures that a service provider only has the permissions necessary to perform their specific tasks. This principle minimizes the risk of unauthorized access or accidental misuse of the system by restricting access to essential areas only. It aligns with the least privilege principle, a cornerstone of effective access control.

Limited Administrator Access with Expiration (Option A):This is helpful but does not ensure that the access granted aligns with the specific job requirements.

Deleting User IDs After Completion (Option C):This is a good practice but applies after the task, not during access.

Access Corresponding to the SLA (Option D):While important, this focuses on timeframes and does not restrict permissions effectively.

Changing default passwords is a critical security measure for IoT devices. Many IoT devices come with default credentials that are widely known and easily exploitable by attackers. Ensuring that these default passwords are changed to strong, unique passwords significantly reduces the risk of unauthorized access. While logging, monitoring, firmware compliance, and network diagram reviews are important security practices, they are secondary to the fundamental step of securing device access through strong authentication.

The most important thing for the company to verify when outsourcing the printing of customer statements is whether the provider’s information security controls are aligned with the company’s. This isbecause customer statements contain sensitive personal and financial information that need to be protected from unauthorized access, disclosure, modification or destruction. The provider’s information security controls should be consistent with the company’s policies, standards and regulations, and should be audited periodically to ensure compliance. The other options are also relevant, but not as critical as information security. References: CISA Review Manual (Digital Version)1, Chapter 3, Section 3.2.2

 Coding standards provide field naming conventions, which are rules for naming variables, constants, functions, classes, and other elements in a program. Coding standards help to ensure consistency, readability, maintainability, and portability of code. Program documentation, access control tables, and data flow diagrams are not part of coding standards. References: CISA Review Manual (Digital Version), Chapter 4, Section 4.3.1

 A database administrator (DBA) should be prevented from having end user responsibilities to avoid a conflict of interest and a violation of the principle of segregation of duties. End user responsibilities may include initiating transactions, authorizing transactions, recording transactions or reconciling transactions. A DBA who has end user responsibilities may compromise the integrity, confidentiality and availability of the data and the database systems. Accessing sensitive information, having access to production files and using an emergency user ID are not end user responsibilities, but rather potential risks or controls associated with the DBA role. References:

The first step when creating a data classification program is to develop a policy (D). A data classification policy is a document that defines the purpose, scope, objectives, roles, responsibilities, and procedures of the data classification program. A data classification policy is essential for establishing the governance framework, standards, and guidelines for the data classification process. A data classification policy also helps to communicate the expectations and benefits of the data classification program to the stakeholders, such as data owners, users, custodians, and auditors12.

Categorizing and prioritizing data (A) is not the first step when creating a data classification program, but the third step. Categorizing and prioritizing data involves defining and applying the criteria and labels for classifying data based on its sensitivity, value, and risk. For example, data can be categorized into public, internal, confidential, or restricted levels. Categorizing and prioritizing data helps to identify and protect the most critical and sensitive data assets of the organization12.

Developing data process maps (B) is not the first step when creating a data classification program, but the fourth step. Developing data process maps involves documenting and analyzing the flow and lifecycle of data within the organization. Data process maps show how data is created, collected, stored, processed, transmitted, used, shared, archived, and disposed of. Developing data process maps helps to understand the context and dependencies of data, as well as to identify and mitigate any potential risks or issues related to data quality, security, or compliance12.

Categorizing information by owner © is not the first step when creating a data classification program, but the second step. Categorizing information by owner involves assigning roles and responsibilities for each type of data based on its ownership and stewardship. Data owners are the individuals or entities that have the authority and accountability for the data. Data stewards are the individuals or entities that have the operational responsibility for managing and maintaining the data. Data custodians are the individuals or entities that have the technical responsibility for implementing and enforcing the security and access controls for the data12.

 Root cause is the most important thing for an IS auditor to determine and understand to develop meaningful recommendations for findings. A root cause is the underlying factor or condition that leads to a problem or issue. A finding is a statement that describes a problem or issue identified during an audit. A recommendation is a suggestion or advice that aims to address or resolve a finding. To develop meaningful recommendations for findings, an IS auditor should determine and understand the root cause of each finding, as this can help to identify the most effective and appropriate actions to prevent or correct the problem or issue. The other options are not as important as determining and understanding the root cause, as they do not directly address or resolve the finding. References: CISA Review Manual, 27th Edition, page 434

A full interruption test is the most realistic and reliable way to ensure that recovery time objectives (RTOs) are met for an organization’s disaster recovery plan (DRP). RTOs are the maximum amount of time that a business can tolerate being offline after a disaster. A full interruption test involves shutting down the primary site and switching over to the backup site, simulating a real disaster scenario. This test can measure the actual time it takes to restore the systems, applications, and functions that are critical for the business continuity. A full interruption test can also reveal any issues or gaps in the DRP that might affect the recovery process.

The other options are not as effective as a full interruption test for ensuring RTOs are met. A cyber resilience test is a type of DR test that focuses on the ability to withstand and recover from cyberattacks. It does not necessarily cover other types of disasters or test the entire DRP. A tabletop test is a low-impact DR test that involves a walkthrough of the DRP with the key stakeholders and staff. It does not involve any actual switching over or testing of the backup systems. A parallel test is a type of DR test that involves running the backup systems alongside the primary systems, without disrupting the normal operations. It does not measure the time it takes to switch over or resume operations at the backup site.

 Developing the CSA questionnaire is an activity that would allow an IS auditor to maintain independence while facilitating a control self-assessment (CSA). An IS auditor can design and provide a CSA questionnaire to help the business units or process owners to evaluate their own controls and identify any issues or improvement opportunities. This will enable an IS auditor to support and guide the CSA process without compromising their objectivity or independence. The other options are activities that would impair an IS auditor’s independence while facilitating a CSA, as they involve implementing, completing, or developing remediation actions for control issues. References:

The best way to track organizational data in a BYOD environment is to enroll the personal devices in the organization’s mobile device management (MDM) program. This will allow the organization to monitor, control, and secure the data on the devices remotely. Employees must also report lost or stolen devices and sign the acceptable use policy, but these are not sufficient to enable tracking of data. References: Info Technology and Systems Resources |COBIT, Risk, Governance … - ISACA, section “Book IT Control Objectives for Sarbanes-Oxley, 4th Edition | Digital | English”

 Identifying required IT skill sets that support key business processes is the first step to enable the alignment of IT staff development plans with IT strategy. An IT strategy is a plan that defines how IT will support the organization’s goals and objectives. Identifying required IT skill sets means determining the knowledge, abilities, and competencies that IT staff need to perform their roles and responsibilities effectively and efficiently. This can help to align IT staff development plans with IT strategy, as well as to identify and address any skill gaps or needs within the IT workforce. The other options are not the first steps to enable alignment, but rather possible subsequent actions that may depend on the required IT skill sets. References:

The best assurance of data integrity after file transfers is hash values. Hash values are unique strings that are generated by applying a mathematical function to the data. Hash values can be used to verify that the data has not been altered or corrupted during the transfer, as any change in the data would result in a different hash value. By comparing the hash values of the source and destination files, one can confirm that the data is identical and intact.

The other options are not as effective as hash values for ensuring data integrity after file transfers. Check digits are digits added to a number to detect errors in data entry or transmission, but they are not reliable for detecting intentional or complex modifications of the data. Monetary unit sampling is a statistical sampling technique used for auditing financial statements, but it is not applicable for verifying data integrity after file transfers. Reasonableness check is a validation method that checks whether the data falls within an expected range or format, but it does not guarantee that the data is accurate or consistent with the source.

 The most critical finding for an IS auditor following up on a recent security incident is that the security weakness facilitating the attack was not identified. This finding indicates that the root cause of the incident was not analyzed, and the vulnerability that allowed the attack to succeed was not remediated. This means that the organization is still exposed to the same or similar attacks in the future, and its security posture has not improved. Identifying and addressing the security weakness is a key step in the incident response process, as it helps to prevent recurrence, mitigate impact, and improve resilience.

The other findings are not as critical as the failure to identify the security weakness, but they are still important issues that should be addressed by the organization. The attack was not automatically blocked by the intrusion detection system (IDS) is a finding that suggests that the IDS was not configured properly, or that it did not have the latest signatures or rules to detect and prevent the attack. The attack could not be traced back to the originating person is a finding that implies that the organization did not have sufficient logging, monitoring, or forensic capabilities to identify and attribute the attacker. Appropriate response documentation was not maintained is a finding that indicates that the organization did not follow a consistent and formal incident response procedure, or that it did not document its actions, decisions, and lessons learned from the incident.

Ineffective incident detectionis the greatest concern becauseearly detection is crucialfor minimizing damage from security incidents. If an organization fails to detect incidentspromptly, attackers may exploit vulnerabilities for extended periods.

Ineffective Incident Detection (Correct Answer – A)

Leads todelayed response, increasingpotential damage.

Example:A company fails to detect a ransomware attack forseveral days, allowing significant data loss.

Ineffective Incident Dashboard (Incorrect – B)

A dashboard helpsvisualizeincidents but doesnot impact detection.

Ineffective Incident Classification (Incorrect – C)

Important, butmisclassificationis asecondary issueif detection fails.

Ineffective Post-Incident Review (Incorrect – D)

Affectsfuture improvementsbut does notimpact immediate response.

Comprehensive and Detailed Explanation:

Earned Value Analysis (EVA) provides a quantitative measure of project progress by comparing planned value, earned value, and actual costs. This gives insight into schedule and budget performance, making it the best tool to assess whether the project is on track.

Critical path (A): Helps in identifying dependencies but not progress.

Work breakdown structure (C): Defines scope but does not measure progress.

Traceability matrix (D): Ensures requirements coverage, not schedule/cost progress.

Linking incidents to problem management activities would most effectively help to reduce the number of repeated incidents in an organization, because problem management aims to identify and eliminate the root causes of incidents and prevent their recurrence. Testing incident response plans, prioritizing incidents, and training incident management teams are all good practices, but they do not directly address the issue of repeated incidents. References: ISACA ITAF 3rd Edition Section 3600

The greatest risk to an organization’s ability to manage QC processes is the lack of policies and procedures that define the QC objectives, standards, methods, roles, and responsibilities. Without policies and procedures, the QC processes may be inconsistent, ineffective, inefficient, or noncompliant with the relevant regulations and best practices. Policies and procedures provide the foundation and guidance for the QC processes and help to ensure their quality, reliability, and accountability.

Quality Control: Meaning, Importance, Definition and Objectives

Implementing business rules to validate employee data entry is the best way to reduce the likelihood of future occurrences of poor data quality that cause customer complaints about receiving different items from what they ordered on the organization’s website. Business rules are logical statements that define the conditions and actions for data validation, such as checking for data completeness, accuracy, consistency, and integrity. Assigning responsibility for improving data quality, investing in additional employee training for data entry, and outsourcing data cleansing activities to reliable third parties are also possible ways to improve data quality, but they are not as effective as implementing business rules to validate employee data entry. References: CISA Review Manual (Digital Version), Chapter 4, Section 4.3.1

A vendor requires privileged access to a key business application. The best recommendation to reduce the risk of data leakage is to implement real-time activity monitoring for privileged roles. This is because real-time activity monitoring can provide visibility and accountability for the actions performed by the vendor with privileged access, such as creating, modifying, deleting, or copying data. Real-time activity monitoring can also enable timely detection and response to any unauthorized or suspicious activities that may indicate data leakage. Including the right-to-audit in the vendor contract is a good practice, but it may not be sufficient to prevent or detect data leakage in a timely manner, as audits are usually performed periodically or on-demand. Performing a review of privileged roles and responsibilities is also a good practice, but it may not address the specific risk of data leakage by the vendor with privileged access. Requiring the vendor to implement job rotation for privileged roles may reduce the risk of collusion or fraud, but it may not prevent or detect data leakage by any individual with privileged access. References: CISA Review Manual (Digital Version), [ISACA Privacy Principles and Program Management Guide]

Audit findings should be communicated as early as possible to avoid misunderstandings, provide an opportunity for corrective action, and ensure transparency.

Option A (Incorrect):The planning phase involves defining audit scope, objectives, and methodology, but findings are not yet available to discuss with management.

Option B (Incorrect):The reporting phase formalizes audit results, but discussing issuesonlyat this stage may lead to delays in corrective action.

Option C (Incorrect):The follow-up phase ensures that management has implemented corrective actions, but this occursafterthe initial discussion of findings.

Option D (Correct):The fieldwork phase is when auditors activelygather evidence, analyze data, and identify issues. Discussing observationsduringthis phase allows for immediate clarification, validation, and resolution of misunderstandings before the final report.

 Team member assignments based on individual competencies is the most important factor to meet the IS audit standard for proficiency. Proficiency is the ability to apply knowledge, skills and experience to perform audit tasks effectively and efficiently. The IS audit standard for proficiency requires that IS auditors must possess the knowledge, skills and discipline to perform audit tasks in accordance with applicable standards, guidelines and procedures. Team member assignments based on individual competencies is a way to ensure that each IS auditor is assigned to audit tasks that match their level of proficiency, and that the audit team as a whole has sufficient and appropriate proficiency to conduct the audit. The other options are not as important as option C, as they do not ensure that the IS auditors have the required proficiency to perform audit tasks. Having a globally recognized audit certification is a way to demonstrate proficiency in IS auditing, but it does not guarantee that the IS auditor has the specific knowledge, skills and experience needed for a particular audit task or system. Technical co-sourcing is a way to supplement the proficiency of the IS audit team by hiring external experts or consultants to perform certain audit tasks or functions, but it does not replace the need for internal IS auditors to have adequate proficiency. Having a supervisor review the new auditors’ work is a way to ensure quality and accuracy of the audit work, but it does not ensure that the new auditors have the necessary proficiency to perform audit tasks independently or competently. References: CISA Review Manual (Digital Version) , Chapter 1: Information Systems Auditing Process, Section 1.4: Audit Skills and Competencies.

The best description of an audit risk is that the financial report may contain undetected material errors. Audit risk is the risk that the auditor expresses an inappropriate opinion on the financial report when it contains material misstatements or errors. Audit risk consists of three components: inherentrisk, control risk, and detection risk. Inherent risk is the susceptibility of an assertion or a control to a material misstatement or error due to factors such as complexity, volatility, fraud, or human error. Control risk is the risk that a material misstatement or error will not be prevented or detected by the internal controls. Detection risk is the risk that the auditor’s procedures will not detect a material misstatement or error that exists in an assertion or a control. References:

The IS auditor should be most concerned if completeness testing has not been performed on the log data, as this could indicate that some logs are missing, corrupted, or tampered with, and that the log aggregation system is not reliable or accurate12. Completeness testing is a process of verifying that all the logs generated by the source systems are successfully collected, transferred, and stored by the log aggregation system, and that there are no gaps or inconsistencies in the log data34. Completeness testing is essential for ensuring the integrity and validity of the log data, and for supporting the risk management practices of the organization.

Recovery facilities providing a redundant combination of Internet connections to the local communications loop is an example of last-mile circuit protection. Last-mile circuit protection is a type of telecommunications continuity that ensures the availability and redundancy of the final segment of the network that connects the end-user to the service provider. The local communications loop, also known as the local loop or subscriber line, is the physical link between the customer premises and the nearest central office or point of presence of the service provider. Byhavingmultiple Internet connections from different providers or technologies, such as cable, DSL, fiber, wireless, or satellite, the recoveryfacilities can avoid losing connectivity in case one of the connections fails or is disrupted by a disaster5.

The first step that the organization should take to ensure that only the corporate network is used for downloading business data is to include a statement in its security policy about Internet use. A security policy is a document that defines the rules, expectations, and overall approach that an organization uses to maintain the confidentiality, integrity, and availability of its data1. A security policy should clearly state the acceptable and unacceptable use of Internet resources, such as personalaccounts with ISPs, and the consequences of violating the policy. A security policy also helps to guide the implementation of technical controls, such as proxy servers, firewalls, or monitoring tools, that can enforce the policy and prevent or detect unauthorized Internet access.

The other options are not the first step that the organization should take, but rather subsequent or complementary steps that depend on the security policy. Using a proxy server to filter out Internet sites that should not be accessed is a technical control that can help implement the security policy, but it does not address the root cause of why users are using personal accounts with ISPs. Keeping a manual log of Internet access is a monitoring technique that can help audit the compliance with the security policy, but it does not prevent or deter users from using personal accounts with ISPs. Monitoring remote access activities is another monitoring technique that can help detect unauthorized Internet access, but it does not specify what constitutes unauthorized access or how to respond to it.

The business case for an information system investment is a document that provides the rationale and justification for the investment, based on the expected costs, benefits, risks, and impacts of the project12. The business case should be available for review until the benefits have been fully realized, because it serves as a baseline for measuring the actual performance and outcomes of the project against the planned ones34. This helps to evaluate the success and value of the investment, and to identify any gaps or issues that need to be addressed5.

SQL injection attacks exploit vulnerabilities in web applications by inserting malicious SQL code into input fields, such as a search box. This can cause the server to execute unintended commands, often revealing restricted information.

Man-in-the-Middle (Option A):This intercepts communication but does not involve code injection.

Denial of Service (DoS) (Option B):This aims to disrupt service, not extract information.

Cross-Site Scripting (Option D):Involves injecting malicious scripts to execute in a user ' s browser but does not extract server-side data.

The forensic principle is to preserve evidence in its original state. Imaging—including capturing residual and deleted data—ensures that the full contents of a storage device are preserved for analysis while maintaining the chain of custody. Hardening (A) may alter system state. Encoding logs (C) is not preservation but transformation. Documenting APIs (D) helps investigation scope but does not preserve evidence. ISACA guidance on digital forensics stresses the importance of bit-level imaging and ensuring evidence integrity through hashing and proper custody documentation.

IT application owners having sole responsibility for architecture approval (B) is a major concern because it indicates a lack of oversight and segregation of duties. EA decisions should be reviewed by a cross-functional governance body to ensure alignment with security, compliance, and business objectives.

Other options:

The CIO chairing the review board (A) may indicate centralized leadership but is not inherently a risk.

EA governing non-IT projects (C) may indicate scope expansion but is not a security risk.

Security requirements being reviewed (D) is a best practice and not a concern.

The auditor’s greatest concern when reviewing data inputs from spreadsheets into the core finance system would be undocumented code that formats data and transmits directly to the database. This is because undocumented code can introduce errors, inconsistencies, and security risks in the data processing and reporting. Undocumented code can also make it difficult to verify the accuracy, completeness, and validity of the data inputs and outputs, as well as to trace the source and destination of the data. Undocumented code can also violate the principles of segregation of duties, as the same person who creates the code may also have access to the data and the database.

The other options are not as concerning as undocumented code, although they may also pose some risks. A lack of complete inventory of spreadsheets and inconsistent file naming may make it challenging to identify and locate the relevant spreadsheets, but they do not directly affect the quality or integrity of the data inputs. The department data protection policy not being reviewed or updated for two years may indicate a lack of awareness or compliance with the current data protection regulations, but it does not necessarily imply that the data inputs are compromised or inaccurate. Spreadsheets being accessible by all members of the finance department may increase the risk of unauthorized or accidental changes to the data, but it can be mitigated by implementing access controls, password protection, and audit trails.

Function point analysis (FPA) is the best methodology to use for estimating the complexity of developing a large business application. FPA is a technique that measures the functionality of a software system based on the user requirements and the business processes that the system supports. FPA assigns a numerical value to each function or feature of the system, based on its type, complexity, and relative size. The total number of function points represents the size and complexity of the system, which can be used to estimate the development effort, cost, and time.

FPA has several advantages over other estimation methods, such as:

It is independent of the technology, programming language, or development methodology used for the system. Therefore, it can be applied consistently across different platforms and environments.

It is based on the user perspective and the business value of the system, rather than the technical details or implementation aspects. Therefore, it can be performed early in the project life cycle, before the design or coding phases.

It is objective and standardized, as it follows a set of rules and guidelines defined by the International Function Point Users Group (IFPUG). Therefore, it can reduce ambiguity and improve accuracy and reliability of the estimates.

It is adaptable and scalable, as it can handle changes in the user requirements or the system scope. Therefore, it can support agile and iterative development approaches.

 Write access to production program libraries presents the greatest risk when granted to a new member of the system development staff. Production program libraries contain executable code that runs on live systems and supports critical business functions. Write access allows a user to modify or delete existing programs, or add new programs to the library. If a user were to make unauthorized or erroneous changes to production programs, it could cause serious disruptions, errors, or security breaches in the organization’s operations. Therefore, writeaccess to production program libraries should be restricted to authorized personnel only, and subject to strict change management controls. 

The correct answer is C. Software escrow agreement. A software escrow agreement is a legal arrangement between three parties: the software developer (licensor), the end-user (licensee), and an escrow agent. The agreement ensures that the software’s source code and other relevant assets are securely stored with the escrow agent, and can be released to the licensee under certain conditions, such as the licensor’s bankruptcy, insolvency, or failure to provide support or maintenance1. A software escrow agreement can provide the licensee with assurance and continuity for the software they depend on, and protect them from losing access or functionality in case of any unforeseen events or disputes with the licensor1.

 Implementing an email containerization solution on personal devices is the best recommendation for an IS auditor, because it allows the organization to separate and secure the email data from the rest of the device data. Email containerization creates a virtual environment that encrypts andisolates the email data, preventing unauthorized access, leakage, or loss of sensitive information12. Requiring passwords or antivirus protection on personal devices may not be sufficient or enforceable, while prohibiting employees from storing companyemail onpersonal devices may not be feasible or practical. References: 1: CISA Review Manual (DigitalVersion), Chapter 5, Section 5.4.3 2: CISA Online Review Course, Module 5, Lesson 4

 File checksums are values that are calculated from the contents of a file and can detect any changes or corruption in the file. They are used to verify that the files that are transferred or processed through system interfaces are not altered in any way. File checksums are more effective than periodic audits, file counts, or IT operator monitoring, which are other types of controls that can help ensure the integrity of system interfaces, but they are not as reliable or timely as file checksums.

Signature-based intrusion detection systems (IDS) are systems that compare network traffic with predefined patterns of known attacks, called signatures. The effectiveness of signature-based IDS depends on how well they can detect new or unknown attacks that are not in their signature database. Therefore, an increase in the number of detected incidents not previously identified is the best indicator of the effectiveness of signature-based IDS, as it shows that they can recognize novel or modified attacks. 

The primary reason an IS auditor should discuss observations with management before delivering a final report is A. Validate the audit observations. This is because discussing the observations with management can help the auditor to ensure that the findings are accurate, complete, and supported by sufficient evidence1. It can also help the auditor to obtain management’s perspective and feedback on the issues and risks identified, and to avoid any misunderstandings or surprises when the final report is issued2.

 The best option to support the organization’s objectives of protecting data confidentiality while transporting data is encryption. Encryption is a process of transforming data into an unreadable form using a secret key or algorithm, so that only authorized parties can access the original data. Encryption protects the confidentiality of data in transit by preventing unauthorized interception,modification, or disclosure of the data. Encryption can also help comply with data privacy and security regulations, such as the GDPR and HIPAA.

The other options are not as effective as encryption in protecting data confidentiality while transporting data. Cryptographic hashes are mathematical functions that generate a fixed-length output from an input, but they do not encrypt the data. Hashes are used to verify the integrity and authenticity of data, but they do not prevent unauthorized access to the data. Virtual local area network (VLAN) is a logical grouping of network devices that share the same broadcast domain, but they do not encrypt the data. VLANs can improve network performance and security by isolating traffic, but they do not protect the data from being intercepted or modified by external attackers. Dedicated lines are physical connections that provide exclusive access to a network or service, but they do not encrypt the data. Dedicated lines can offer higher bandwidth and reliability, but they do not guarantee the confidentiality of the data from being compromised by physical tampering or eavesdropping.

A project deliverable is a tangible or intangible product or service that is produced as a result of a project and delivered to the customer or stakeholder. A project deliverable can be either an intermediate deliverable that is part of the project process or a final deliverable that is the outcome of the project.

An agile software development methodology is a project management approach that involves breaking the project into phases and emphasizes continuous collaboration and improvement. Teams follow a cycle of planning, executing, and evaluating. Agile software development methodologies value working software over comprehensive documentation and respond to change over following a plan.

Rapidly created working prototypes are most likely to be a project deliverable of an agile software development methodology because they:

Provide early and frequent feedback from customers and stakeholders on the functionality and usability of the software product

Allow for rapid validation and verification of the software requirements and design

Enable continuous improvement and adaptation of the software product based on changing customer needs and expectations

Reduce the risk of delivering a software product that does not meet customer needs or expectations

Increase customer satisfaction and trust by delivering working software products frequently and consistently

Some examples of agile software development methodologies that use rapidly created working prototypes as project deliverables are:

Scrum - a framework that organizes the work into fixed-length sprints (usually 2-4 weeks) and delivers potentially shippable increments of the software product at the end of each sprint1

Extreme Programming (XP) - a methodology that focuses on delivering high-quality software products through practices such as test-driven development, pair programming, continuous integration, and frequent releases2

Rapid Application Development (RAD) - a methodology that emphasizes rapid prototyping and user involvement throughout the software development process3

The other options are not likely to be project deliverables of an agile software development methodology.

Strictly managed software requirements baselines are not likely to be project deliverables of an agile software development methodology. A software requirements baseline is a set of agreed-upon and approved software requirements that serve as the basis for the software design, development, testing, and delivery. A strictly managed software requirements baseline is a software requirements baseline that is controlled and changed only through a formalchange management process. Strictly managed software requirements baselines are more suitable for traditional or waterfall software development methodologies that follow a linear and sequential process of defining, designing, developing, testing, and delivering software products. Strictly managed software requirements baselines are not compatible with agile software development methodologies that embrace change and flexibility in the software requirements based on customer feedback and evolving needs.

Extensive project documentation is not likely to be project deliverables of an agile software development methodology. Project documentation is any written or electronic information that describes or records the activities, processes, results, or decisions of a project. Extensive project documentation is project documentation that covers every aspect of the project in detail and requires significant time and effort to produce and maintain. Extensive project documentation is more suitable for traditional or waterfall software development methodologies that rely on comprehensive documentation to communicate and document the project scope, requirements, design, testing, and delivery. Extensive project documentation is not compatible with agile software development methodologies that value working software over comprehensive documentation and use minimal documentation to support the communication and collaboration among the project team members.

Automated software programming routines are not likely to be project deliverables of an agile software development methodology. Automated software programming routines are programs or scripts that perform repetitive or complex tasks in the software development process without human intervention. Automated software programming routines can improve the efficiency, quality, and consistency of the software development process by reducing human errors, saving time, and enforcing standards. Automated software programming routines can be used in any software development methodology, but they are not specific to agile software development methodologies. Automated software programming routines are not considered as project deliverables because they are not part of the final product that is delivered to the customer.

 A feasibility study is an assessment that determines the likelihood of a proposed project being successful, such as a new system development1. A feasibility study typically covers various aspects of the project, such as technical, economic, operational and legal feasibility2. The IS auditor’s role is to audit the feasibility study and ensure that it is objective, realistic and reliable3.

One of the most important aspects of a feasibility study is the economic feasibility, which analyzes the costs and benefits of the proposed system and compares them with alternative solutions2. Theeconomic feasibility study should include a detailed breakdown of the development, implementation and operational costs, as well as the expected revenues, savings and intangible benefits of the system3. The IS auditor should review the cost-benefit documentation for reasonableness and accuracy, and verify that the assumptions and calculations are valid and supported by evidence3.

The other options are not directly related to auditing the feasibility study of a system development project. Reviewing qualifications of key members of the project team (option A) is more relevant to auditing the project management and human resources aspects of the project. Reviewing the request for proposal (RFP) to ensure that it covers the scope of work (option B) is more relevant to auditing the procurement and vendor selection process of the project. Ensuring that vendor contracts are reviewed by legal counsel (option D) is more relevant to auditing the legal and contractual aspects of the project.

 The first course of action when a data breach has occurred due to malware is to quarantine the impacted systems. This means isolating the infected systems from the rest of the network and preventing any further communication or data transfer with them. This can help contain the spread of the malware, limit the damage and exposure of sensitive data, and facilitate the investigation and remediation of the incident. Quarantining the impacted systems can also help preserve the evidence and logs that may be needed for forensic analysis or legal action.

The most effective way to identify exfiltration of sensitive data by a malicious insider is to establish behavioral analytics monitoring. Behavioral analytics is the process of analyzing the patterns and anomalies in user behavior to detect and prevent insider threats. Behavioral analytics can help identify unusual or suspicious activities, such as accessing sensitive data at odd hours, transferring large amounts of data to external devices or locations, or using unauthorized applications or protocols. Behavioral analytics can also help correlate data from multiple sources, such as network logs, user profiles, and access rights, to provide a holistic view of user activity and risk.

Data loss prevention (DLP) software is a tool that can help prevent exfiltration of sensitive data by a malicious insider, but it is not the most effective way to identify it. DLP software can block or alert on unauthorized data transfers based on predefined rules and policies, but it may not be able to detect sophisticated or stealthy exfiltration techniques, such as encryption, steganography, or data obfuscation.

Reviewing perimeter firewall logs is a way to identify exfiltration of sensitive data by a malicious insider, but it is not the most effective way. Perimeter firewall logs can show the traffic volume and destination of data transfers, but they may not be able to show the content or context of the data. Perimeter firewall logs may also be overwhelmed by the amount of normal traffic and miss the signals of malicious exfiltration.

Providing ongoing information security awareness training is a way to reduce the risk of exfiltration of sensitive data by a malicious insider, but it is not a way to identify it. Information security awareness training can help educate users on the importance of protecting sensitive data and the consequences of violating policies and regulations, but it may not deter or detect those who are intentionally or maliciously exfiltrating data.

The primary focus of the IS auditor reviewing the first year of the project should be regression testing. Regression testing is a type of testing that ensures that the existing functionality of the system is not affected by the changes or upgrades made to the system. Since the project involves upgrading the ERP system hosting the general ledger, which is a critical and complex component of the finance department, it is important to verify that the upgrade does not introduce any errors or defects that could compromise the accuracy, completeness, and reliability of the financial data and reports. Regression testing can help identify and resolve any issues before they affect the users and the business processes.

Unit testing, network performance, and user acceptance testing (UAT) are also important aspects of the project, but they are not the primary focus of the IS auditor in the first year. Unit testing is a type of testing that verifies that each individual module or component of the system works as expected. Network performance is a measure of how well the system can communicate and exchange data with other systems and devices over a network. User acceptance testing (UAT) is a type of testing that validates that the system meets the user requirements and expectations. These aspects are more relevant in later stages of the project, when the system is more developed and ready for deployment.

The best recommendation for the auditor to make is D. Line management should regularly review and request modification of access rights. Access rights are the permissions and privileges granted to users to access, view, modify, or delete data or resources on a system or network1. Excessive rights are access rights that are not necessary or appropriate for a user’s role or function, and may pose a risk of unauthorized or inappropriate use of data or resources2. Therefore, it is important to ensure that access rights are alignedwith the principle of least privilege, which means that users should only have the minimum level of access required to perform their duties2.

Line management is responsible for overseeing and supervising the activities and performance of their staff, and ensuring that they comply with the organization’s policies and standards3. Therefore, line management should regularly review and request modification of access rights for their staff, as they are in the best position to:

Understand the roles and functions of their staff, and determine the appropriate level of access rights needed for them to perform their duties effectively and efficiently.

Monitor and evaluate the usage and behavior of their staff, and identify any changes or anomalies that may indicate excessive or inappropriate access rights.

Communicate and collaborate with IT security or system administrators, who are responsible for granting, revoking, or modifying access rights, and request any necessary adjustments or corrections.

The best course of action for an IS auditor when an auditee is unable to close all audit recommendations by the time of the follow-up audit is to evaluate the residual risk due to open issues. Residual risk is the risk that remains after the implementation of controls or mitigating actions. Evaluating the residual risk due to open issues can help the IS auditor assess the impact and likelihood of the potential threats and vulnerabilities that have not been addressed by the auditee, as well as the adequacy and effectiveness of the existing controls or mitigating actions. Evaluating the residual risk due to open issues can also help the IS auditor prioritize and communicate the open issues to the auditee and other stakeholders, such as senior management or audit committee, and recommend appropriate actions or escalation procedures.

Ensuring the open issues are retained in the audit results is a course of action for an IS auditor when an auditee is unable to close all audit recommendations by the time of the follow-up audit, but it is not the best one. Ensuring the open issues are retained in the audit results can help the IS auditor document and report the status and progress of the audit recommendations, as well as provide a basis for future follow-up audits. However, ensuring the open issues are retained in the audit results does not provide an analysis or evaluation of the residual risk due to open issues, which is more important for informing decision-making and action-taking.

Terminating the follow-up because open issues are not resolved is not a course of action for an IS auditor when an auditee is unable to close all audit recommendations by the time of the follow-up audit, but rather a consequence or outcome of it. Terminating the follow-up because open issues are not resolved may indicate that the auditee has failed to comply with the agreed-upon actions or deadlines, or that the IS auditor has encountered significant obstacles or resistance from the auditee. Terminating the follow-up because open issues are not resolved may also trigger further actions or sanctions from the IS auditor or other authorities, such as issuing a qualified or adverse opinion, withholding certification, or imposing penalties.

Recommending compensating controls for open issues is not a course of action for an IS auditor when an auditee is unable to close all audit recommendations by the time of the follow-up audit, but rather a possible outcome or result of it. Compensating controls are alternative or additional controls that are implemented to reduce or eliminate the risk associated with a weakness or deficiency in another control. Recommending compensating controls for open issues may be appropriate when the auditee is unable to implement the original audit recommendations due to technical, operational,financial, or other constraints, and when the compensating controls can provide a similar or equivalent level of assurance. However, recommending compensating controls for open issues requires a prior evaluation of the residual risk due to open issues, which is more important for determining whether compensating controls are necessary and feasible.
