Explanation
Application patch management is the formal process of evaluating, testing, approving, and deploying patches in a controlled manner before they reach production systems. Had a proper patch management process been followed, the update would have been tested in a non-production environment first, the issue would have been discovered before impact, and a rollback plan would have been in place. Application hardening reduces attack surface but does not govern the update lifecycle. Access controls limit who can use an application, not how updates are deployed. Configuration baselines document a known good state but do not define the process for safely applying updates.
