Audit Authentication Policy Change

  • 아티클

Audit Authentication Policy Change determines whether the operating system generates audit events when changes are made to authentication policy.

Changes made to authentication policy include:

  • Creation, modification, and removal of forest and domain trusts.

  • Changes to Kerberos policy under Computer Configuration\Windows Settings\Security Settings\Account Policies\Kerberos Policy.

  • When any of the following user logon rights is granted to a user or group:

    • Access this computer from the network

    • Allow logon locally

    • Allow logon through Remote Desktop

    • Logon as a batch job

    • Logon as a service

  • Namespace collision, such as when an added trust collides with an existing namespace name.

This setting is useful for tracking changes in domain-level and forest-level trust and privileges that are granted to user accounts or groups.

Event volume: Low.
