What is Patching?
A patch is a set of updates to a server or its supporting data designed to update, fix and improve, including fixing security vulnerabilities and other bugs. They may be applied to program files on a storage device or in computer memory. Patches may be permanent or temporary.
In a brief overview, you need to perform the following tasks for patch management:
1. Create a patch catalog.
2. Analyze the target to determine the patches that need to deploy.
3. Deploy the required patches to targets requiring remediation.
4. Analyze the targets again to ensure each server has the correct patch.
