CAS-005 Exam Dumps : CompTIA SecurityX Certification Exam

The best answer is D. Host-based encryption . The strongest clue is that the company has proprietary information on its hard drives and consultants must travel with company-managed devices because BYOD is prohibited. That makes protection of data at rest on the endpoint the primary concern. Host-based encryption protects the contents of the drive if a laptop is lost, stolen, or physically accessed during travel. CompTIA’s SecurityX certification emphasizes building secure solutions across complex environments and supporting resilient enterprise protection, which includes securing endpoints and sensitive data stored on them.

Why the other options are not best:

A. Virtual hardware does not directly protect the data on the hard drive if the device is lost or stolen. B. Measured boot helps validate platform integrity at startup, but it does not primarily protect confidential data at rest. C. Secure enclave can protect certain secrets and key material, but it is narrower than full host-based encryption for an entire laptop drive. Because the requirement is specifically about proprietary data on traveling endpoints, full device or host-based encryption is the most beneficial control.

The organization is most concerned about Generative AI improving phishing and social engineering attacks. Tools like ChatGPT can generate highly convincing phishing emails, fake websites, and human-like interactions that bypass traditional detection methods. Employees who were trained to spot poor grammar or obvious scams may now struggle to detect AI-crafted exploits.

Option A relates to compliance but not AI-driven threats. Option B (overreliance on AI bots) is operational risk, not phishing. Option D (differential analysis) applies to AI privacy issues, not phishing.

CAS-005 emphasizes adapting training to emerging threats, including AI-enabled social engineering. This ensures users remain resilient against modern attacks, making C the correct answer.
