To avoid crashes in production servers after installing a security patch, what should an IS auditor ensure?

To ensure that production servers do not experience crashes after installing a security patch, it is vital for an IS auditor to confirm the presence of a robust change management process. This process is essential because it provides a structured approach to managing changes, including the installation of patches. A well-documented change management process typically includes stages such as planning, testing, approval, implementation, and post-implementation review.

By relying on a good change management process, organizations can mitigate risks associated with changes made to production environments. This includes conducting thorough testing of patches in controlled environments, reviewing their impact, and ensuring that rollbacks or contingency plans are in place in case issues arise post-deployment. A sound change management process fosters communication among teams, ensuring that all stakeholders understand the potential effects of the changes and are prepared for any complications.

While the other options present important components of the patch management lifecycle—such as adhering to release notes, performing thorough testing, and conducting risk assessments—they can be incorporated within a larger change management framework. However, without an overarching change management process, the risks of instability in production environments remain high, making it crucial to prioritize establishing and following this structured approach.
