Fix Recommendation

Where SQL Server Trace is in use, implement tracking of SELECTs on categorized data at the application level, using the system stored procedure sp_trace_generateevent to write the tracking records to the Trace used for audit purposes. Include failed attempts in the tracking.

If SQL Server Audit is in use, design and deploy an Audit that captures all auditable events and data items. The script provided in the supplemental file Audit.sql can be used as the basis for this. Supplement the standard audit data as necessary, using Extended Events and/or triggers.

Alternatively, to add the necessary data capture to an existing server audit specification, run the script:
USE [master];
GO
ALTER SERVER AUDIT SPECIFICATION <server_audit_specification_name> WITH (STATE = OFF);
GO
ALTER SERVER AUDIT SPECIFICATION <server_audit_specification_name> ADD (SCHEMA_OBJECT_ACCESS_GROUP);
GO
ALTER SERVER AUDIT SPECIFICATION <server_audit_specification_name> WITH (STATE = ON);
GO

Check Contents

Review the system documentation to determine whether it is required to track categories of information, such as classification or sensitivity level. If it is not, this is not applicable (NA).

If neither SQL Server Audit nor SQL Server Trace is in use for audit purposes, this is a finding.

If SQL Server Trace is in use for audit purposes, review the application(s) using the database to verify that all SELECT actions on categorized data, including unsuccessful attempts, are being audited; and that the tracking records are written to the SQL Server Trace used for audit purposes. If not, this is a finding.


If SQL Server Audit is in use, proceed as follows.

The basic SQL Server Audit configuration provided in the supplemental file Audit.sql uses the broad, server-level audit action group SCHEMA_OBJECT_ACCESS_GROUP for this purpose. SQL Server Audit's flexibility makes other techniques possible.

If an alternative technique is in use and demonstrated effective, this is not a finding.

Determine the name(s) of the server audit specification(s) in use.

To look at audits and audit specifications, in Management Studio's object explorer, expand
<server name> >> Security >> Audits
and
<server name> >> Security >> Server Audit Specifications.
Also,
<server name> >> Databases >> <database name> >> Security >> Database Audit Specifications.

Alternatively, review the contents of the system views with "audit" in their names.

Run the following to verify that all SELECT, INSERT, UPDATE, and DELETE actions on tables and views are being audited:
USE [master];
GO
SELECT * FROM sys.server_audit_specification_details WHERE server_specification_id =
(SELECT server_specification_id FROM sys.server_audit_specifications WHERE [name] = '<server_audit_specification_name>')
AND audit_action_name = 'SCHEMA_OBJECT_ACCESS_GROUP';

If no row is returned, this is a finding.

If the audited_result column is not "FAILURE" or "SUCCESS AND FAILURE", this is a finding.
