azure.roleassignment

Role assignments map role definitions to principals. The Azure object only contains the unique ID of the principal, however we attempt to augment the object with the prinicpal name, display name and type from AAD.

Augmenting with data from AAD requires executing account to have permissions to read from the Microsoft AAD Graph. For Service Principal Authorization the Service Principal must have the permissions to read all users’ full profiles. Azure CLI authentication will provide the necessary permissions to run the policy locally.

example

Return role assignments with the Owner role.

policies:
    - name: role-assignment-owner
      resource: azure.roleassignment
      filters:
        - type: role
          key: properties.roleName
          op: eq
          value: Owner
example

Return assignments with the principal name custodian@example.com

policies:
  - name: assignment-by-principal-name
    resource: azure.roleassignment
    filters:
       - type: value
         key: principalName
         op: eq
         value: custodian@example.com
example

Delete the assignment with principal name custodian@example.com.

Note: The permissions required to run the delete action requires delete permissions to Microsoft.Authorization. The built-in role with the necessary permissions is Owner.

policies:
  - name: delete-assignment-by-principal-name
    resource: azure.roleassignment
    filters:
       - type: value
         key: principalName
         op: eq
         value: custodian@example.com
    actions:
       - type: delete
