CAS-005 Exam Dumps : CompTIA SecurityX Certification Exam

The logs indicate unauthorized access from104.18.16.29, an external IP, to the building camera’s administrative console during off-hours.Restricting access only to approved IPsensures that only authorized personnel can remotely control the cameras, reducing the risk of unauthorized access and manipulation.

Implementing WAF protection (A)secures against web application attacks but does not restrict unauthorized administrative access.

Upgrading the firmware (B)is good security hygiene but does not immediately mitigate the active threat.

Blocking IP 104.18.16.29 (D)is a temporary measure, as an attacker can switch to another IP. A better long-term solution is whitelisting trusted IPs.

Code signing uses cryptographic digital signatures to prove that software or updates come from a trusted source and have not been altered. In the SecurityX CAS-005 objectives, this is covered under security engineering and cryptographic assurance mechanisms.

Envelope encryption protects confidentiality but does not authenticate the source.

File integrity monitoring detects file changes but does not confirm the origin of the update.

Application control manages which software can run but does not ensure authenticity of distributed files.Only code signing meets all three objectives: verifying the source, ensuring authorization, and proving integrity.

The logs indicate multiple failed login attempts for user10, who may have been part of the staff reduction 60 days prior. If user10 ' s account was removed, and their home directory deleted, any applications or services relying on files or configurations within that directory would fail. This scenario is common when service accounts are not properly identified and preserved during staff reductions.

Ensuring that service accounts are documented and maintained separately from user accounts is essential to prevent unintended disruptions to applications and services.
