Patch Management
Patch management is the process by which we keep track of the changes or updates we do to a finished software product. Proper patch management is very important to keep track of changes and to identify the problem area easily when a bug or security flaw is identified. In order to understand patch management, we need to know what a patch is. A patch is a piece of code written to fix a bug or security flaw or give additional features to an existing software product. Every software or application needs to be Patched periodically to keep it updated with new features and make it more secure against newer security threats.
Patch management is the process of testing and installing multiple code changes or patches on existing applications and tools thereby enabling them to stay updated and secure. It also involves determining which patches are necessary and removing the unnecessary ones without affecting the functionality of the product. Most of the software patches are security related but sometimes it may be for some functionality issues.
