In addition to manual approval, you can also set an automatic approval rule for definition updates and Endpoint Protection updates.
This will configure WSUS to automatically approve Endpoint Protection definition updates downloaded by WSUS.
This option is used by Endpoint Protection clients to download definition updates if they have not been able to download updates from another source.
This update method can be useful if there is a problem with your Configuration Manager infrastructure that prevents the delivery of updates.This is done in the Configure Definition Update Sources dialog box when you create an antimalware policy.
