What is one key consideration when applying patches?

When applying patches, creating a mitigation plan if patches cannot be applied is a crucial consideration. This practice ensures that organizations maintain a proactive stance toward security risks. If vulnerabilities are identified and patches cannot be immediately implemented—whether due to system compatibility issues, operational constraints, or other factors—having a mitigation plan in place allows the organization to address the potential risks in an alternative manner.

This could involve implementing compensating controls, such as additional layers of security, enhanced monitoring, or limited access to the affected systems until the patch can be applied. It effectively reduces the window of exposure and helps maintain compliance with regulatory requirements, thus safeguarding critical infrastructure.

The other choices may not adequately reflect the complexities and critical nature of effectively managing vulnerabilities through patches. For example, applying patches uniformly across all departments may not take into account the unique needs and risk profiles of different environments. Limiting patches to only critical systems may leave other vulnerable areas unprotected. Deferring updates can leave outdated systems exposed to threats for a prolonged period, which may violate best practices in risk management. Thus, having a well-thought-out mitigation plan offers flexibility and ensures comprehensive risk management when immediate patching isn't feasible.
