17.2.3 Ensure 'Audit Distribution Group Management' is set to include 'Success' (DC only) - Success

Information

This subcategory reports each event of distribution group management, such as when a distribution group is created, changed, or deleted or when a member is added to or removed from a distribution group. If you enable this Audit policy setting, administrators can track events to detect malicious, accidental, and authorized creation of group accounts. Events for this subcategory include:

4744: A security-disabled local group was created.

4745: A security-disabled local group was changed.

4746: A member was added to a security-disabled local group.

4747: A member was removed from a security-disabled local group.

4748: A security-disabled local group was deleted.

4749: A security-disabled global group was created.

4750: A security-disabled global group was changed.

4751: A member was added to a security-disabled global group.

4752: A member was removed from a security-disabled global group.

4753: A security-disabled global group was deleted.

4759: A security-disabled universal group was created.

4760: A security-disabled universal group was changed.

4761: A member was added to a security-disabled universal group.

4762: A member was removed from a security-disabled universal group.

4763: A security-disabled universal group was deleted.

The recommended state for this setting is to include: Success.

Rationale:

Auditing these events may provide an organization with insight when investigating an incident. For example, when a given unauthorized user was added to a sensitive distribution group.




Impact:

If no audit settings are configured, or if audit settings are too lax on the computers in your organization, security incidents might not be detected or not enough evidence will be available for network forensic analysis after security incidents occur. However, if audit settings are too severe, critically important entries in the Security log may be obscured by all of the meaningless entries and computer performance and the available amount of data storage may be seriously affected. Companies that operate in certain regulated industries may have legal obligations to log certain events or activities.

Solution

To establish the recommended configuration via GP, set the following UI path to include Success:

Computer Configuration\Policies\Windows Settings\Security Settings\Advanced Audit Policy Configuration\Audit Policies\Account Management\Audit Distribution Group Management

Default Value:

No Auditing.
