CompTIA Updated CAS-005 Exam Questions and Answers by avneet

The output indicates that the software tool contains hard-coded credentials, which attackers can exploit to bypass user access controls and load the database. The mostlikely recommendation is to remove hard-coded credentials from the source code. Here’s why:

Security Best Practices: Hard-coded credentials are a significant security risk because they can be easily discovered through reverse engineering or simple inspection of the code. Removing them reduces the risk of unauthorized access.

Credential Management: Credentials should be managed securely using environment variables, secure vaults, or configuration management tools that provide encryption and access controls.

Mitigation of Exploits: By eliminating hard-coded credentials, the organization can prevent attackers from easily bypassing authentication mechanisms and gaining unauthorized access to sensitive systems.

SecurityX CAS-005 emphasizes automation with validation in security operations. Security Orchestration, Automation, and Response (SOAR) platforms can integrate with Threat Intelligence Platforms (TIPs) to verify threat indicators before triggering automated endpoint isolation through EDR APIs. This approach reduces the spread of malware while minimizing the chance of isolating clean systems due to false positives.

Isolating endpoints on any alert (B) is high-risk and can disrupt business operations.

Manual review (C) is too slow for fast-moving threats.

Suppressing alerts (D) risks missing critical events entirely.

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 routing entry 0.0.0.0/0 forces all traffic from remote clients—including traffic destined for the public internet—through the VPN tunnel. This is called full-tunnel VPN routing. While it ensures strong security by forcing all traffic to pass through corporate controls, it can also overload VPN gateways and cause slow access to both internal and external applications, as seen in this scenario.

The correct fix is to enable split tunneling (B). Split tunneling allows only corporate traffic (e.g., private IP ranges or internal applications) to flow through the VPN, while internet-bound traffic routes directly to the internet. This reduces congestion on VPN concentrators, improves performance for remote users, and ensures efficient use of bandwidth.

Moving servers to a screened subnet (A) relates to internal segmentation but does not fix the VPN bottleneck. NAC (C) enforces device compliance but does not address routing inefficiencies. DNS over HTTPS (D) secures name resolution but is unrelated to network congestion.

Thus, enabling split tunneling balances security and performance for remote workers.
