Which of the following is a responsibility of a 3rd party regarding software vulnerability mitigation?

The responsibility of a third party regarding software vulnerability mitigation primarily includes reviewing security patching processes. This involves evaluating and ensuring that the systems in place for managing and applying security patches are effective and compliant with best practices and standards. By reviewing these processes, third parties can help identify gaps, recommend improvements, and ensure that vulnerabilities are addressed in a timely and efficient manner.

This oversight is crucial because it helps organizations maintain their cybersecurity posture and minimize risk. An effective patch management process is essential to protect systems from known vulnerabilities that could be exploited by adversaries.

In contrast, other responsibilities mentioned, like applying security patches or implementing full-disk encryption, may fall more directly on the organization utilizing the software or the primary provider, rather than a third-party entity. Similarly, granting physical access to systems does not relate to software vulnerability mitigation but rather pertains to security controls and access management.
