The rule "Okta Group Admin Role Assigned" is designed to detect when an admin role is assigned to a group within the Okta identity platform. This is important for maintaining security around user roles and access management, as improper assignment of admin roles could lead to unauthorized access and compromise organizational data. The rule monitors system logs for events that indicate a privilege grant to groups, specifically focusing on events categorized under 'group.privilege.grant'. It triggers an alert whenever such an event is detected, provided the conditions specified in the rule are met, such as the event being marked as a privilege grant and the user's actions aligned with the threshold set. The severity of this rule is classified as high, indicating it could pose significant risks if triggered by unauthorized actions. The expected behavior of the rule is to log successful privilege grants while also monitoring for unsuccessful attempts which provide additional context for threat detection.
