Configure Source Rules

IMPORTANT: Activity Count and Activity Type or Category are mandatory rules to complete your custom anomaly rule statement. The Incomplete Rule message will be displayed if these rules are not added.

The Source rule allows you to detect and monitor the trusted and untrusted activities performed by users on the service. You can also define the rule with other parameters such as Activity Type or Category, Activity Count, Trust, Device, and more. Anomalies are triggered when a user performs any activities on a service that exceeds the expected activity count from a configured source type and network.

The Source rule allows you to select the source type for the rule. Source types are Trusted and Untrusted. You can also select or deselect a reason for the selected source type from the list.
