CISSP Dumps with Practice Exam Questions Answers

 Supplying a duress alarm for personnel exposed to the public is the most cost-effective method to provide a reactive control for protecting personnel in public areas. A duress alarm is a device that allows a person to signal for help in case of an emergency, such as an attack, a robbery, or a medical condition. A duress alarm can be activated by pressing a button, pulling a cord, or speaking a code word. A duress alarm can alert security personnel, law enforcement, or other responders to the location and nature of the emergency, and initiate appropriate actions. A duress alarm is a reactive control because it responds to an incident after it has occurred, rather than preventing it from happening.

The other options are not as cost-effective as supplying a duress alarm, as they involve more expensive or complex technologies or resources. Installing mantraps at the building entrances is a preventive control that restricts the access of unauthorized persons to the facility, but it also requires more space, maintenance, and supervision. Enclosing the personnel entry area with polycarbonate plastic is a preventive control that protects the personnel from physical attacks, but it also reduces the visibility and ventilation of the area. Hiring a guard to protect the public area is a deterrent control that discourages potential attackers, but it also involves paying wages, benefits, and training costs.

 When an organization plans to relocate, the most important consideration from a data security perspective is to conduct a gap analysis of the new facilities against the existing security requirements. A gap analysis is a process that identifies and evaluates the differences between the current state and the desired state of a system or a process. In this case, the gap analysis would compare the security controls and measures implemented in the old and new locations, and identify any gaps or weaknesses that need to be addressed. The gap analysis would also help to determine the costs and resources needed to implement the necessary security improvements in the new facilities.

The other options are not as important as conducting a gap analysis, as they do not directly address the data security risks associated with relocation. Ensuring the fire prevention and detection systems are sufficient to protect personnel is a safety issue, not a data security issue. Reviewing the architectural plans to determine how many emergency exits are present is also a safety issue, not a data security issue. Revising the Disaster Recovery and Business Continuity (DR/BC) plan is a good practice, but it is not a preventive measure, rather a reactive one. A DR/BC plan is a document that outlines how an organization will recover from a disaster and resume its normal operations. A DR/BC plan should be updated regularly, not only when relocating.

Purging or re-imaging the hard disk drive of a laptop before traveling to a high risk area will reduce the risk of data compromise or theft in case the laptop is lost, stolen, or seized by unauthorized parties. Purging or re-imaging the hard disk drive will erase all the data and applications on the laptop, leaving only the operating system and the essential software. This will minimize the exposure of sensitive or confidential information that could be accessed by malicious actors. Purging or re-imaging the hard disk drive should be done using secure methods that prevent data recovery, such as overwriting, degaussing, or physical destruction.

The other options will not reduce the risk to the laptop as effectively as purging or re-imaging the hard disk drive. Examining the device for physical tampering will only detect if the laptop has been compromised after the fact, but will not prevent it from happening. Implementing more stringent baseline configurations will improve the security settings and policies of the laptop, but will not protect the data if the laptop is bypassed or breached. Changing access codes will make it harder for unauthorized users to log in to the laptop, but will not prevent them from accessing the data if they use other methods, such as booting from a removable media or removing the hard disk drive.

A company whose IT services are being delivered from a Tier 4 data center should be most concerned with application failures when preparing a companywide BCP. A BCP is a document that describes how an organization will continue its critical business functions in the event of a disruption or disaster. A BCP should include a risk assessment, a business impact analysis, a recovery strategy, and a testing and maintenance plan.

A Tier 4 data center is the highest level of data center classification, according to the Uptime Institute. A Tier 4 data center has the highest level of availability, reliability, and fault tolerance, as it has multiple and independent paths for power and cooling, and redundant and backup components for all systems. A Tier 4 data center has an uptime rating of 99.995%, which means it can only experience 0.4 hours of downtime per year. Therefore, the likelihood of a power, storage, or network failure in a Tier 4 data center is very low, and the impact of such a failure would be minimal, as the data center can quickly switch to alternative sources or routes.

However, a Tier 4 data center cannot prevent or mitigate application failures, which are caused by software bugs, configuration errors, or malicious attacks. Application failures can affect the functionality, performance, or security of the IT services, and cause data loss, corruption, or breach. Therefore, the IT manager should be most concerned with application failures when preparing a BCP, and ensure that the applications are properly designed, tested, updated, and monitored.

A Business Impact Analysis (BIA) is a process that identifies and evaluates the potential effects of natural and man-made disasters on business operations. The BIA questionnaire is a tool that collects information from business process owners and stakeholders about the criticality, dependencies, recovery objectives, and resources of their processes. The BIA questionnaire should include questions that:

• Identify the operational impacts of a business interruption, such as loss of revenue, customer satisfaction, reputation, legal obligations, etc.
• Identify the financial impacts of a business interruption, such as direct and indirect costs, fines, penalties, etc.
• Determine the technological dependence of the business processes, such as hardware, software, network, data, etc.
• Establish the recovery time objectives (RTO) and recovery point objectives (RPO) for each business process, which indicate the maximum acceptable downtime and data loss, respectively.

The BIA questionnaire should not include questions that determine the risk of a business interruption occurring, as this is part of the risk assessment process, which is a separate activity from the BIA. The risk assessment process identifies and analyzes the threats and vulnerabilities that could cause a business interruption, and estimates the likelihood and impact of such events. The risk assessment process also evaluates the existing controls and mitigation strategies, and recommends additional measures to reduce the risk to an acceptable level.
