Fix Recommendation

Deploy an audit to audit when data classifications are deleted. See the supplemental file "SQL 2016 Audit.sql".

Check Contents

Review the system documentation to determine if SQL Server is required to audit when data classifications are deleted.

If this is not required, this is not a finding.

If the documentation does not exist, this is a finding.

Determine if an audit is configured and started by executing the following query.

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

If no records are returned, this is a finding.

If the auditing the retrieval of privilege/permission/role membership information is required, execute the following query to verify the "SCHEMA_OBJECT_ACCESS_GROUP" is 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 = 'SCHEMA_OBJECT_ACCESS_GROUP'

If the "SCHEMA_OBJECT_ACCESS_GROUP" is not returned in an active audit, this is a finding.
