SQL4-00-036600 - Trace or Audit records must be generated when categorized information (e.g., classification levels/security levels) is created.

Information

Changes in categorized information must be tracked. Without an audit trail, unauthorized access to protected data could go undetected.

For detailed information on categorizing information, refer to FIPS Publication 199, Standards for Security Categorization of Federal Information and Information Systems, and FIPS Publication 200, Minimum Security Requirements for Federal Information and Information Systems.

Use of SQL Server Audit is recommended. All features of SQL Server Audit are available in the Enterprise and Developer editions of SQL Server 2014. It is not available at the database level in other editions. For this or legacy reasons, the instance may be using SQL Server Trace for auditing, which remains an acceptable solution for the time being. Note, however, that Microsoft intends to remove most aspects of Trace at some point after SQL Server 2016.

Since Trace does not provide for tracking SELECT statements, it is necessary to provide that part of the tracking at the application level. Because of this, it may also be appropriate to audit INSERT actions at the application level. However, to capture all INSERTs, whether they come from the application or bypass it, the Trace must be configured to cover them.

Solution

Where SQL Server Trace is in use, create triggers to raise a custom event for INSERTs on each table holding categorized information. The examples provided in the supplemental file CustomTraceEvents.sql can serve as the basis for these.

Add a block of code to the supplemental file Trace.sql for each custom event class (integers in the range 82-91; the same event class may be used for all such triggers) used in these triggers. Execute Trace.sql.

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
