SQL Server Audit Action Group:
AUDIT_CHANGE_GROUP
This important group allows you to track changes to audit and audit specification objects which have an impact of course on the audit trail within SQL Server. This group also tracks audit failures and audit session changes. If any auditing is enabled at all on a given server it follows then that this group should certainly be enabled in the server audit specification so that audit trail integrity can be insured.
If you enable this group at the server level, you will track changes to both audit objects and server audit specifications. It will also track changes to all database audit specifications.
If you enable this group in a database it will track changes to database audit specifications within that database.
