CAS-005 Exam Dumps and Practice Questions

To reduce the number of failed patch deployments, the systems administrator should implement a robust change management process. Change management ensures that all modifications to systems or applications are planned, tested, and approved before deployment. This systematic approach reduces the risk of unplanned changes that can cause patch failures and ensures that patches are deployed in a controlled and predictable manner.

CompTIA SecurityX Study Guide: Emphasizes the importance of change management in maintaining system integrity and ensuring successful patch deployments.

ITIL (InformationTechnology Infrastructure Library) Framework: Provides best practices for change management in IT services.

'The Phoenix Project' by Gene Kim, Kevin Behr, and George Spafford: Discusses the critical role of change management in IT operations and its impact on system stability and reliability.

This scenario describes an attack where the attacker mimics the CEO's voice to deceive the CFO, likely using AI-generated audio. According to the CompTIA SecurityX CAS-005 study guide (Domain 1: Security Strategy and Risk Management, 1.2), a deepfake attack involves using artificial intelligence to create realistic but fake audio, video, or other media to impersonate someone. In this case, the voice similarity suggests a deepfake audio attack, which is a targeted social engineering tactic.

Option A:Smishing involves SMS-based phishing, not voicecalls.

Option C:Automated exploit generation refers to creating software exploits, not impersonation.

Option D:Spear phishing targets specific individuals but typically via email, not voice-based impersonation.

Option B:Deepfake is the most accurate, as it describes AI-driven impersonation of the CEO's voice.

CompTIA SecurityX CAS-005 Official Study Guide, Domain 1: Security Strategy and Risk Management, Section 1.2: 'Identify advanced social engineering attacks, including deepfakes.'

CAS-005 Exam Objectives, 1.2: 'Analyze the impact of AI-based attacks on security.'

Attack surface reductionfocuses on minimizingunnecessary services, open ports, and vulnerabilities, reducing the exposure to potential adversaries. This aligns withzero trust and least privilege principles.

Secure Boot (A)helps ensure system integrity but does not minimize exposed services.

Disabling third-party integrations (C)may help, but broader attack surface reduction is the best first step.

Limiting access (D)is important but does not directly reduce exposed services.

The best answer is A. Automated patching. The scenario already states that updates are available, the vulnerabilities must be remediated within 24 hours, and the risk of unsuccessful remediation is low because production impact would not be significant. That makes direct, rapid deployment of fixes the most appropriate practice. CompTIA's SecurityX objectives include operational response and automation themes, and the official exam summary explicitly references automation capabilities in multiple areas. In this scenario, automation is not just helpful; it is the most practical way to meet the time requirement consistently across IoT devices.

Why the other options are incorrect:

B . Vulnerability prioritization is something you do before deciding what to remediate first, but the question already gives the prioritization context and asks how to resolve the issue. C. Forced restart does not remediate the vulnerabilities. D. SOAR playbook creation might support a broader workflow in the future, but creating a playbook is slower and less direct than simply using automated patching when patches already exist and risk is acceptable. Under the stated conditions, automated patching is the best-fit operational response.

Geofencingallows the device to be restricted based on its physical location --- disabling or locking devices when they move outside of trusted zones.Full disk encryptionensures that if a device is lost, the data remains inaccessible to unauthorized users. Containerization protects specific apps or data, but does not disable the entire device. Patch management, allow/blocklists, and geotagging serve other important functions but are not directly linked to the requirements in this scenario.
