Goal

Detects the creation of Entra ID (Azure AD) Administrative Units (AUs). The use of this type of this policy may indicate suspicious activity if an environment is not utilizing AUs.

Strategy

Monitor Azure Active Directory logs for @properties.category:AdministrativeUnit and @evt.name: "Add administrative unit" where the event is not a restricted administrative unit.

Triage and response

  1. Review if administrative units are used by the organization.
  2. Review evidence of anomalous activity for the user creating an administrative unit.
  3. Determine if there is a legitimate reason for the user creating an administrative unit.
