User Assigned New Privileged Role
Id | 746ddb63-f51b-4563-b449-a8b13cf302ec |
Rulename | User Assigned New Privileged Role |
Description | Identifies when a new eligible or active privileged role is assigned to a user. Does not alert on PIM activations. Any account eligible for a role is now being given privileged access. If the assignment is unexpected or into a role that isn’t the responsibility of the account holder, investigate.
