Patch management

Patch management is the process of updating operating systems and other software to correct an error or enhance performance.

A well-defined and structured patch management process helps to address the new vulnerabilities related to operating systems. Timely updating of patches helps to secure operating systems and applications.

Patches are generally applied to operating systems, applications, and network software. Patches will help to fix the vulnerability in the system.

Patches should be applied through a structured change management process that includes approval, testing, user acceptance testing, and proper documentation. Testing a patch prior to implementation is one of the most important aspects, as deploying an untested patch may cause the system to fail. Also, appropriate rollback procedures should be in place in case of unexpected failure.
