Goal

Detect when any user logs in to Azure AD without multi-factor authentication.

Strategy

This rule monitors Azure Activity logs for Active Directory logs and detects when any @evt.category has a value of SignInLogs, and @properties.authenticationRequirement has a value of singleFactorAuthentication.

Triage and response

  1. Reach out to the user to determine if the login was legitimate.
  2. If the login was legitimate, request that the user enables 2FA.
  3. If the login wasn’t legitimate, rotate the credentials.
  4. Review all user accounts to ensure MFA is enabled.
