CAS-005 Exam Dumps : CompTIA SecurityX Certification Exam

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.

The Common Vulnerability Scoring System (CVSS) v3.1 uses three metric groups to calculate overall scores:Base,Temporal, andEnvironmental.

Base (E):Mandatory metrics assessing exploitability (e.g., attack vector) and impact (confidentiality, integrity, availability).

Temporal (A):Optional metrics reflecting the current state of the vulnerability (e.g., exploit availability, remediation level).

Environmental (F):Optional metrics tailoring the score to the organization’s context (e.g., security requirements).

B, C, D (Availability, Integrity, Confidentiality):These are subcomponents of the Base Impact metrics, not standalone groups.

G (Impact):A categorywithin Base, not a group.

H (Attack vector):A single Base metric, not a group.

The best way to address these requirements is to apply Role-Based Access Controls (RBAC) combined with geolocation policies. RBAC ensures that customers are authenticated and authorized to access only the data they are entitled to, thereby minimizing data exposure risks. At the same time, geolocation policies enforce restrictions on which regions customers can access data from, helping with compliance requirements such as GDPR or regional sovereignty laws.

Option B (replicating data in each customer environment) is inefficient, expensive, and introduces additional risks related to data sprawl. Option C (regional hosting with unique links) complicates access management and does not inherently prevent exposure or enforce strong authentication. Option D (restricting to a single region provider) removes flexibility and may conflict with customer needs for global access.

Therefore, implementing RBAC along with geolocation controls provides fine-grained access management, ensures compliance, prevents unnecessary data exposure, and is scalable for a global cloud environment.
