Credential Abuse in Admin Sign-Ins — Success Following Failure or Anomalous Access
This rule analyzes Microsoft Entra (Azure AD) sign-in logs over a 30-day period for access to sensitive administrative applications (e.g., Azure Portal, Microsoft Intune, Defender). It flags user-application-IP sessions that exhibit unusual characteristics, such as login successes following failures, access from multiple geographic locations, or the use of multiple client types, which may indicate account compromise or unauthorized access.
