What it detects

This rule flags stale sign-in conditions for accounts assigned to privileged roles when a stale sign-in alert incident is generated. Attackers may rely on dormant privileged accounts for stealthy persistence and reduced likelihood of detection. The detection relies on Azure Privileged Identity Management telemetry that records the stale sign-in risk event type.
