SQL Server Audit Action Group:
SCHEMA_OBJECT_PERMISSION_CHANGE_GROUP
This group tracks attempts to grant, deny or revoke permissions on schema objects such as a table, view or stored procedure.
This is an important audit action group because permission changes are critical to the security of the server and the information on it.
If you enable this group in a database audit specification, it will track permission changes to schema objects within that database only. If you enable this group in a server audit specification, it will track permission changes to schema objects in all databases within that SQL Server instance.
