Patch Management refers to updating and patching systems, and particularly to tools and systems which automate this process for a large number of systems.
Patch Management refers to the important and never-ending task of installing software updates on systems, including the procedures involved with installing updates, defining update policies for an organization, and tools/systems to help with the patching process.
Patch Management may include patch selection methods (anything from manually reading the CVE list to automated vulnerability scans), patch deployment methods (manually installing patches, various software packages), and patch testing procedures (virtual environments, staged deployment, etc.)
Many tools (free and commercial) have evolved to help alleviate the workload. You may want to include a tag specific to the software you are using. Some examples include:
chef puppet sccm windows-update wsus
