Microsoft patch classifications
When creating a rule, you select a classification for the Microsoft patches.
Third party and application patches do not use these categories.
When selecting classifications to approve be aware of the patching requirements of your customers. For example if a customer must remain on a specific version of Internet Explorer, do not select Updates, Update Rollups, or Feature Packs as IE could be part of any of those packages.
During the patch detection scan, we can find patches from all Microsoft channels:
-
Band B: includes new and released security fixes
-
Band C: optional, cumulative, non-security preview releases
-
Out-of-band: fixes for recently-identified issues or vulnerabilities
