This rule is designed to detect anomalous activities originating from infrequent or unrecognized geographic locations within Microsoft Cloud Services. It leverages Microsoft's anomaly detection capabilities through Cloud App Security to examine user activities correlated to their historical access patterns. The rule triggers when an event is logged indicating that a user from the organization has performed an action from a location that has not been frequently accessed or has never been accessed before by any user within the organization. Such anomalies can potentially indicate compromised accounts or unauthorized access, especially if linked to command-and-control behaviors commonly exploited by attackers. The rule specifically focuses on events categorized under 'Activity from infrequent country' and expects successful executions of these events to warrant further investigation, serving as an alert mechanism for security teams to assess potential threats and malicious activities.
