Description

To mitigate the impact of credential exposure or compromise, role assignments should be scoped down to the least level of privilege needed to perform their responsibilities. This rule identifies when a managed identity is assigned a role that has permissions that are more broad than what is regularly used. Datadog considers a permissions gap to be large when the number of unused permissions is greater than 40% of the total permissions count.

Rationale

By comparing what actions a managed identity has performed in the last 15 days with what their roles permit, we can identify a permissions gap. This gap should be removed to mitigate the impact of a potential compromise.

Remediation

Datadog recommends reducing the permissions assigned to user to the minimum necessary for them to fulfill their duties. Azure Activity Logs provide a comprehensive view of actual user actions. These actions should be compared with the permissions sets allocated to the user and the permissions adjusted more tightly to accord with actual activity.
