This subcategory reports the results of events generated after a Kerberos authentication TGT request. Kerberos is a distributed authentication service that allows a client running on behalf of a user to prove its identity to a server without sending data across the network. This helps mitigate an attacker or server from impersonating a user.

4768: A Kerberos authentication ticket (TGT) was requested.

4771: Kerberos pre-authentication failed.

4772: A Kerberos authentication ticket request failed.

The recommended state for this setting is: Success and Failure.


Auditing these events may be useful when investigating a security incident.


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

Computer Configuration\Policies\Windows Settings\Security Settings\Advanced Audit Policy Configuration\Audit Policies\Account Logon\Audit Kerberos Authentication Service


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.
