Patch Management
Patch management is the process of updating operating systems and other software to correct errors or enhance performance.
A well-defined and structured patch management process helps to address new vulnerabilities related to operating systems. The timely update of patches helps to secure operating systems and applications.
Patches are generally applied to operating systems, applications, and network software. They help fix vulnerabilities in the system.
Patches should be applied through a structured change management process that includes approval, testing, user acceptance testing, and proper documentation. The testing of a patch prior to implementation is of utmost importance. Deploying untested patches may cause the system to fail. Furthermore, appropriate rollback procedures should be in place in case of unexpected failure.
