CAS-005 Dumps with Practice Exam Questions Answers

For a distributed workforce needing access to compliance-bound on-premises systems, VPN access ensures encrypted, authenticated connectivity while limiting exposure. SecurityX CAS-005 emphasizes using VPNs for secure remote access when direct migration to cloud is not possible.

Moving legacy systems to cloud (B) violates the compliance constraints.

SDN security controls (C) are beneficial but do not inherently provide secure remote connectivity.

Microsegmentation (D) is useful for internal lateral movement control but does not solve remote access needs.

Software Composition Analysis (SCA) is the best method for identifying all components, dependencies, and open-source libraries used inan application. It ensures that organizations track and manage vulnerabilities in third-party code before deployment.

SCA tools generate a Software Bill of Materials (SBOM), which provides a full representation of the code and modules used in the application.

Other options:

Static Application Security Testing (SAST) (C) checks for vulnerabilities but does not map dependencies.

Interactive Application Security Testing (IAST) (D) works at runtime, not before deployment.

Runtime Application Self-Protection (RASP) (B) works while the application is running.

Implementing a Single Sign-On (SSO) solution and integrating it with applications is the best way to manage the situation and decrease risks. Here’s why:

Reduced Password Fatigue: SSO allows users tolog in once and gain access to multiple applications and systems without needing to remember and manage multiple passwords. This reduces the likelihood of users writing down passwords.

Improved Security: By reducing the number of passwords users need to manage, SSO decreases the attack surface and potential for password-related security breaches. It also allows for the implementation of stronger authentication methods.

User Convenience: SSO improves the user experience by simplifying the login process, which can lead to higher productivity and satisfaction.

Sinkholing, or DNS sinkholing, is a method used to redirect malicious traffic to a safe destination. This technique is often employed by security teams to prevent access to malicious domains by substituting a benign destination IP address.

In the given logs, users from the finance department are accessing www.bank.com and receiving HTTP status code 495. This status code is typically indicative of a client certificate error, which can occur if the DNS traffic is being manipulated or redirected incorrectly. The consistency in receiving the same HTTP status code across different users suggests a systematic issue rather than an isolated incident.

Recursive DNS resolution failure (A) would generally lead to inability to resolve DNS at all, not to a specific HTTP error.

DNS poisoning (B) could result in usersbeing directed to malicious sites, but again, would likely result in a different set of errors or unusual activity.

Incorrect DNS setup (D) would likely cause broader resolution issues rather than targeted errors like the one seen here.

By reviewing the provided data, it is evident that the DNS traffic for www.bank.com is being rerouted improperly, resulting in consistent HTTP 495 errors for the finance department users. Hence, the most likely cause is that the DNS traffic is being sinkholed.

The actions described fall under Operational Security (OPSEC), which is the practice of identifying critical information, analyzing potential adversary intelligence collection, and implementing measures to protect sensitive details from disclosure. In this case, the ISAC report highlights how adversaries may use photos shared on social media as reconnaissance, revealing details about technology or configurations inside secure facilities.

By disabling cameras and location services on corporate devices and blocking access to social media from corporate and guest networks, the CISO is reducing the chance of inadvertent information disclosure. This prevents employees from unintentionally leaking images or metadata that adversaries could exploit.

Adversary emulation (A) involves simulating threat actors’ tactics in controlled exercises, which is not what is occurring here. Open-source intelligence (C) is the method adversaries use to gather data, not the defensive practice the CISO is implementing. Social engineering (D) describes manipulative attacks against humans, but this control is preventive, not reactive.

Thus, these measures are clear examples of Operational Security to limit information exposure.
