Fix Recommendation

Add the "SUCCESSFUL_LOGIN_GROUP" to the server audit specification.
USE [master];
GO

ALTER SERVER AUDIT SPECIFICATION STIG_AUDIT_SERVER_SPECIFICATION WITH (STATE = OFF);
GO

ALTER SERVER AUDIT SPECIFICATION STIG_AUDIT_SERVER_SPECIFICATION ADD (SUCCESSFUL_LOGIN_GROUP);
GO

ALTER SERVER AUDIT SPECIFICATION STIG_AUDIT_SERVER_SPECIFICATION WITH (STATE = ON);
GO

Alternatively, enable "Both failed and successful logins"
In SQL Management Studio:
Right-click on the instance >> Select "Properties" >> Select "Security" on the left hand side >> Select "Both failed and successful logins" >> Click "OK"

Check Contents

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.

Execute the following query to verify the "SUCCESSFUL_LOGIN_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 = 'SUCCESSFUL_LOGIN_GROUP'

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

If "SUCCESSFUL_LOGIN_GROUP" is not in the active audit, determine whether "Both failed and successful logins" is enabled.

In SQL Management Studio:
Right-click on the instance >> Select "Properties" >> Select "Security" on the left hand side >> Check the setting for "Login auditing"

If "Both failed and successful logins" is not selected, this is a finding.
