description: This rule flags successful "Activity from infrequent country" events reported by Microsoft Cloud App Security when an activity originates from a location the organization’s users have not recently, or ever, visited. Attackers commonly use atypical geolocations to evade baseline behavior and to blend in with legitimate access patterns. Detection relies on threat management telemetry from the SecurityComplianceCenter event source, including the event name and success status.
