To detect service principal scope creep in Entra ID, you can build a 90-day behavioral baseline of SPN activity and compare it against recent actions to calculate a weighted drift score. This identifies gradual privilege or access expansions.

Investigating SPN behavioral drift requires AADServicePrincipalSignInLogs, AuditLogs, and SecurityAlerts data sources. These logs provide the necessary sign-in patterns, permission change records, and threat alerts to corroborate scope drift.

Behavioral baseline drift scoring compares recent SPN activity against a 90-day baseline across multiple dimensions, such as resources accessed and locations. It calculates a weighted score to flag significant deviations indicating potential access creep.

Yes, you can use scope drift detection to investigate a compromised service principal credential. It correlates sudden changes in accessed resources or IP addresses with AuditLogs and SecurityAlerts to identify potential misuse before it escalates.

The best way to identify access expansion in Entra ID automation accounts is to monitor deviations from their established behavioral baseline. Correlating unexpected resource access with AuditLogs confirms if scope drift indicates potential compromise.

You need SecurityAlerts data to comprehensively monitor service principal access creep. While drift scoring detects behavioral deviations, correlating these signals with SecurityAlerts and AuditLogs provides full context for security investigations.
