Investigate Conditional Access policy changes by correlating user actions with audit logs and sign-in data within Microsoft Sentinel to determine if a policy modification caused access blocks.

Users receive Azure AD error codes 53000, 50074, or 530032 when Conditional Access policies block their access. This skill correlates these specific sign-in failures with recent policy state transitions.

Detect security control bypasses by analyzing Conditional Access policy state transitions from enabled to disabled or report-only, then correlating those specific audit log modifications with user sign-in failures.

Yes, you can use Microsoft Sentinel AuditLogs and SigninLogs to identify unauthorized Conditional Access policy modifications by tracking policy state transitions and correlating them with user privilege abuse.

Analyze Conditional Access policy state transitions in Microsoft Sentinel by querying AuditLogs for policy changes and linking them to SigninLogs to pinpoint enabled, disabled, or report-only states causing blocks.
