Check Contents

Check the server documentation for a list of approved users with access to SQL Server Audits.

To create, alter, or drop a server audit, principals require the ALTER ANY SERVER AUDIT or the CONTROL SERVER permission. To view an Audit log requires the CONTROL SERVER permission. To use Profiler, ALTER TRACE is required.

Review the SQL Server permissions granted to principals. Look for permissions ALTER ANY SERVER AUDIT, ALTER ANY DATABASE AUDIT, CONTROL SERVER, ALTER TRACE:

SELECT login.name, perm.permission_name, perm.state_desc
FROM sys.server_permissions perm
JOIN sys.server_principals login
ON perm.grantee_principal_id = login.principal_id
WHERE permission_name in ('CONTROL SERVER', 'ALTER ANY DATABASE AUDIT', 'ALTER ANY SERVER AUDIT','ALTER TRACE')
and login.name not like '##MS_%';

If unauthorized accounts have these privileges, this is a finding.
