Audit: Force audit policy subcategory settings (Windows Vista or later) to override audit policy category settings

Published: November 15, 2012

Updated: November 15, 2012

Applies To: Windows 7, Windows 8, Windows 8.1, Windows Server 2003, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows Vista, Windows XP



This security policy reference topic for the IT professional describes the best practices, location, values, and security considerations for this policy setting.

The applicable Windows operating systems allow audit policy to be managed in a more precise way by using audit policy subcategories.

There are over 40 auditing subcategories that provide precise details about activities on a computer. For information about these subcategories, see the Advanced Security Audit Policy Settings.

  • Enabled

  • Disabled

  1. Leave the setting enabled. This provides the ability to audit events at the category level without revising a policy.

There are no differences in this policy for operating systems beginning with Windows Vista and Windows Server 2008.

This section describes features and tools that are available to help you manage this policy.

None. Changes to this policy become effective without a computer restart when they are saved locally or distributed through Group Policy.

In Windows Server 2008 R2 and Windows 7, all auditing capabilities are integrated in Group Policy. This allows administrators to configure, deploy, and manage these settings in the Group Policy Management Console (GPMC) or Local Security Policy snap-in for a domain, site, or organizational unit (OU).

To manage an audit policy by using subcategories without requiring a change to Group Policy, the SCENoApplyLegacyAuditPolicy registry value , prevents the application of category-level audit policy from Group Policy and from the Local Security Policy administrative tool. This registry value is available in Windows Vista and Windows 7.

If the category level audit policy that is set here is not consistent with the events that are currently being generated, the cause might be that this registry key is set.

For information about displaying and manipulating audit policies from the command line, see Auditpol.

This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.

Prior to the introduction of auditing subcategories in Windows Vista, it was difficult to track events at a per-system or per-user level. The larger event categories created too many events, and the key information that needed to be audited was difficult to find.

Enable audit policy subcategories as needed to track specific events.

The individual audit policy subcategories available in Windows Vista and Windows Server 2008 are not exposed in the interface of Group Policy tools. Administrators can deploy a custom audit policy that applies detailed security audit settings to Windows Vista–based or Windows Server 2008 computers in a Windows Server 2008, Windows Server 2003, or Windows 2000 domain. But the advanced security audit policies are available in the interface of Group Policy in Windows Server 2008 R2.

If you attempt to modify an audit setting by using Group Policy after enabling this setting through the command-line tools, the Group Policy audit setting is ignored in favor of the custom policy setting. To modify audit settings by using Group Policy, you must first disable the SCENoApplyLegacyAuditPolicy key.

ImportantImportant
Be very cautious about audit settings that can generate a large volume of traffic. For example, if you enable success or failure auditing for all of the Privilege Use subcategories, the high volume of audit events that are generated can make it difficult to find other types of entries in the Security log. Such a configuration could also have a significant impact on system performance.
