This finding includes subrules that provide more specific information about each instance of this finding.

The following list shows all possible subrules:

• external_service_account_added_to_policy, external_member_added_to_policy: Detection of privileges granted to IAM users and service accounts that are not members of your organization or, if Security Command Center is activated at the project level only, your project.

If Security Command Center activation is only at the project level, then the detector uses only the project's IAM policies as context. If a sensitive IAM grant to an external member occurs, and there are less than three existing IAM policies that are similar to it, this detector generates a finding.
