Check Contents

Check that SQL Server Audit is being used for the STIG compliant audit.
Determine if an audit is configured and started by executing the following query. If no records are returned, this is a finding.

SELECT name AS 'Audit Name',
status_desc AS 'Audit Status',
audit_file_path AS 'Current Audit File'
FROM sys.dm_server_audit_status

Execute the following query to verify the required audit actions are included in the server audit specification:

SELECT a.name AS 'AuditName',
s.name AS 'SpecName',
d.audit_action_name AS 'ActionName',
d.audited_result AS 'Result'
FROM sys.server_audit_specifications s
JOIN sys.server_audits a ON s.audit_guid = a.audit_guid
JOIN sys.server_audit_specification_details d ON s.server_specification_id = d.server_specification_id
WHERE a.is_state_enabled = 1
AND d.audit_action_name IN ('DATABASE_OBJECT_OWNERSHIP_CHANGE_GROUP'
,'DATABASE_OBJECT_PERMISSION_CHANGE_GROUP'
,'DATABASE_OWNERSHIP_CHANGE_GROUP'
,'DATABASE_PERMISSION_CHANGE_GROUP'
,'DATABASE_ROLE_MEMBER_CHANGE_GROUP'
,'SCHEMA_OBJECT_OWNERSHIP_CHANGE_GROUP'
,'SCHEMA_OBJECT_PERMISSION_CHANGE_GROUP'
,'SERVER_OBJECT_OWNERSHIP_CHANGE_GROUP'
,'SERVER_OBJECT_PERMISSION_CHANGE_GROUP'
,'SERVER_PERMISSION_CHANGE_GROUP'
,'SERVER_ROLE_MEMBER_CHANGE_GROUP')

If the any of the following audit actions are not returned in an active audit, this is a finding.

DATABASE_OBJECT_OWNERSHIP_CHANGE_GROUP
DATABASE_OBJECT_PERMISSION_CHANGE_GROUP
DATABASE_OWNERSHIP_CHANGE_GROUP
DATABASE_PERMISSION_CHANGE_GROUP
DATABASE_ROLE_MEMBER_CHANGE_GROUP
SCHEMA_OBJECT_OWNERSHIP_CHANGE_GROUP
