CAS-005 Exam Dumps : CompTIA SecurityX Certification Exam

To support email authenticity and enable analysis by a third-party platform, the protocols must verify the sender’s identity and provide metadata for inspection. According to the CompTIA SecurityX CAS-005 study guide (Domain 3: Cybersecurity Technology, 3.2):

DMARC (Domain-based Message Authentication, Reporting, and Conformance):DMARC builds on SPF and DKIM to enforce policies for email authenticity and provides reporting mechanisms to share authentication results with third parties for analysis.

DKIM (DomainKeys Identified Mail):DKIM adds a cryptographic signature to emails, allowing recipients to verify the sender’s domain and ensure the email’s integrity.

These two protocols are essential for authenticity and reporting.

Option C (TLS):TLS ensures encryption during transmission but does not address authenticity or reporting.

Option D (SPF):SPF verifies sender IP addresses but lacks reporting capabilities without DMARC.

Option E (DNSSEC):DNSSEC secures DNS queries but is not specific to email authenticity.

Option F (MX):MX records define mail servers, not authenticity or reporting.

A centralized Software Bill of Materials (SBoM) is the best solution for identifying vulnerabilities in container images in aprivate repository. An SBoM provides a comprehensive inventory of all components, dependencies, and their versions within a container image, facilitating quick evaluation and response to vulnerabilities.

Why Centralized SBoM?

Comprehensive Inventory: An SBoM lists all software components, including their versions and dependencies, allowing for thorough vulnerability assessments.

Quick Identification: Centralizing SBoM data enables rapid identification of affected containers when a vulnerability is disclosed.

Automation: SBoMs can be integrated into automated tools for continuous monitoring and alerting of vulnerabilities.

Regulatory Compliance: Helps in meeting compliance requirements by providing a clear and auditable record of all software components used.

Other options, while useful, do not provide the same level of comprehensive and efficient vulnerability management:

A. SAST scan reports: Focuses on static analysis of code but may not cover all components in container images.

C. CIS benchmark compliance reports: Ensures compliance with security benchmarks but does not provide detailed component inventory.

D. Credentialed vulnerability scan: Useful for in-depth scans but may not be as efficient for quick vulnerability evaluation.
