How Patch Management Works

 The methods which are used for patch management will vary slightly according to the infrastructure design for each company information system.  That said here is a general description of how patch management is typically deployed.

Most companies with large infrastructures implement automated patch management systems which reduce the requirements for manpower that would otherwise be needed for manual implementation. Other companies choose to outsource patch management to a qualified company which will perform this service from a remote location.

An automated patch management system involves the installation of a client agent that allows network administrators to control patch distribution from a web-based interface.  This type of system allows network administrators to configure the settings for patch distribution and generate log reports to check the status of patches.
