CAS-005 Exam Dumps : CompTIA SecurityX Certification Exam

The best solution to address reported vulnerabilities in third-party libraries is integrating a Static Application Security Testing (SAST) tool as part of the development pipeline. Here’s why:

Early Detection: SAST tools analyze source code for vulnerabilities before the code is compiled. This allows developers to identify and fix security issues early in the development process.

Continuous Security: By integrating SAST tools into the CI/CD pipeline, the organization ensures continuous security assessment of the codebase, including third-party libraries, with each code commit and build.

Comprehensive Analysis: SAST tools provide a detailed analysis of the code, identifying potential vulnerabilities in both proprietary code and third-party dependencies, ensuring that known issues in libraries are addressed promptly.

The SIEM already contains multiple events that, if correlated, would have indicated an active attack sequence on VM001—such as denied connections, IPS alerts, malware detection, and then an allowed connection. CAS-005 Security Operations objectives emphasize log correlation as a way to enhance detection by linking related events across different time stamps and data sources into a single, higher-confidence alert.

Option A (adding EDR logs) could add visibility but does not address the need to connect existing events for earlier detection.

Option C (improving parsing) ensures readability but does not create actionable alerts.

Option D (creating a new malware detection rule) is redundant since malware detection already appeared in logs; the issue was the lack of correlation to act on it in time.

By correlating IDS, IPS, firewall, and malware detection logs, the SIEM can raise a higher-priority alert before the attack is completed.

The most critical considerations are trust boundaries (C) and supply chain access (E). Trust boundaries define where sensitive data crosses between systems or organizations, requiring strict cryptographic protections—especially important in government and commercial environments subject to crypto-export controls.

Supply chain access is also critical because hardware and software are sourced from external vendors. If suppliers are compromised, attackers could introduce malicious code, backdoors, or tampered firmware, endangering customers worldwide.

Option A (contractual obligations) and B (legal hold) are compliance-related but not direct security threats. Option D (cloud services enumeration) is irrelevant unless the storage is cloud-based. Option F (homomorphic encryption) is an advanced technology but not required for base threat modeling.

CAS-005 highlights modeling adversary capabilities at trust boundaries and accounting for supply chain risks, making C and E the most important.
