The table highlights that tampering threats (IDs 02 and 03) are rated Critical, making them the most significant risks. These threats involve malicious insiders inserting backdoors or attackers injecting malicious code into third-party libraries. To mitigate such risks, organizations must implement a secure software development lifecycle (SDLC) with formalized code scanning, gate checks, and supply chain validation.

Option C directly addresses these issues. Secure development practices include static/dynamic code analysis, dependency checks, peer reviews, and mandatory approvals before code promotion. This approach detects backdoors, prevents unauthorized modifications, and reduces the likelihood of compromised libraries being integrated.

Option A (PAM with conditional access) mitigates privilege escalation but does not address software tampering. Option B (rate limiting and federation) reduces brute-force authentication risks (ID 05) but not critical tampering. Option D (Zero Trust with microsegmentation) strengthens network defense but does not secure the integrity of source code or libraries.

Therefore, a secure SDLC with gate checks and code scanning is the best mitigation for the most critical threats identified.

To minimize downtime, testing should occur in a virtual lab, not production. The best approach is to test solutions methodically: implement one solution at a time, run an attack simulation, collect metrics, roll back, and repeat. This isolates each solution’s effectiveness, ensuring accurate metrics for decision-making without production impact.

Option A:Testing all solutions simultaneously muddies the results—metrics won’t show which solution worked.

Option B:Collecting metrics before the simulation misses the point of testing against the attack.

Option C:Correct—tests each solution independently with simulation and metrics, minimizing downtime via virtual lab use.

Option D:Like A, combining solutions obscures individual effectiveness.

To meet the requirements of only allowing internally signed applications, preventing unauthorized software installations, and logging attempts to run unauthorized software, configuring application control with blocked hashes and enterprise-trusted root certificates is the best solution. This approach ensures that only applications signed by trusted certificates are allowed to execute, while all other attempts are blocked and logged. It effectively prevents unauthorized software installations by restrictingexecution to pre-approved applications.
