CAS-005 Exam Dumps : CompTIA SecurityX Certification Exam

The SIEM report shows that some devices, such as VM003 (Critical server) and NET003 (IPS), are DOWN and therefore not reporting logs. In security monitoring, the absence of log data from critical systems creates dangerous blind spots. If logs are missing, attacks can proceed undetected, or investigations may lack the data needed for incident response.

The most effective action is to perform a non-reporting device assessment (C). This means identifying and correcting issues where devices fail to send logs, whether due to outages, misconfigurations, or integration gaps. Ensuring all critical devices, especially servers and intrusion prevention systems, consistently send logs to the SIEM strengthens overall visibility and monitoring posture.

Option A (time calibration) is important for correlation accuracy but does not address missing log feeds. Option B (centralized use case library) enhances detection but only works if the SIEM is receiving complete data. Option D (resiliency plan) helps protect log retention but is irrelevant if logs are never received in the first place.

Therefore, fixing non-reporting log sources is the highest priority to improve monitoring effectiveness.

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.

Dynamic Application Security Testing (DAST) is crucial for identifying and addressing security vulnerabilities during the software development life cycle (SDLC). Ensuring that DAST scans are routinely scheduled helps in maintaining a secure development process.

Why Routine DAST Scans?

Continuous Security Assessment: Regular DAST scans help in identifying vulnerabilities in real-time, ensuring they are addressed promptly.

Compliance: Routine scans ensure that the development process complies with security standards and regulations.

Proactive Threat Mitigation: Regular scans help in early detection and mitigation of potential security threats, reducing the risk of breaches.

Integration into SDLC: Ensures security is embedded within the development process, promoting a security-first approach.

Other options, while relevant, do not directly address the continuous assessment and proactive identification of threats:

A. If developers are unable to promote to production: This is more of an operational issue than a security assessment.

B. If DAST code is being stored to a single code repository: This concerns code management rather than security testing frequency.

D. If role-based training is deployed: While important, training alone does not ensure continuous security assessment.
