SQL Server Audit Action Group:
SERVER_OBJECT_PERMISSION_CHANGE_GROUP
This group tracks changes of permissions on "server objects". We are unsure of what constitutes a "server object", but apparently this includes server master keys, server credentials and cryptographic providers.
This would seem to be an important audit action group because ownership changes are significant to the security of the system.
