CompTIA Updated CAS-005 Exam Questions and Answers by ariya

Microsegmentation is a critical strategy within Zero Trust architecture that enhances context-aware access systems by dividing the network into smaller, isolated segments. This reduces the attack surface and limits lateral movement of attackers within the network. It ensures that even if one segment is compromised, the attacker cannot easily access other segments. This granular approach to network security is essential for enforcing strict access controls and monitoring within Zero Trust environments.

SecurityX CAS-005 endpoint security and network control objectives emphasize least privilege network access.

Creating a firewall rule to allow outbound traffic only via a proxy (A) ensures centralized inspection and control.

Configuring the proxy to allow only the required FQDNs for EDR management communication (C) limits exposure to necessary destinations.Options D and E allow broader access than necessary, and B would block required communications entirely. F relies on blocklists instead of allowlists, which is less secure for high-assurance environments.

The Subject Alternative Name (SAN) field in an X.509 certificate specifies additional hostnames, FQDNs, or IP addresses that the certificate will secure. To allow mutual TLS authentication for multiple hostnames and an IP address, these identities must be included in the SAN field.

Organizational Unit (B) is an informational attribute, not related to TLS authentication.

Extended Key Usage (C) defines purpose (e.g., serverAuth, clientAuth) but not hostnames.

“Certificate extension” (D) is a generic term; SAN is the specific required extension.

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.
