+      An authorized organizations description describes a list of organizations

+      owned by different organizations at the enforcement points, or (2) with certain
+      asset (for example, device) have been authorized to access the resources in
+      another organization at the enforcement points.

+        The direction of the authorization relationship between this organization
+        and the organizations listed in the "orgs" field. The valid values for this
+        field include the following:
+        
+        AUTHORIZATION_DIRECTION_FROM: Allows this organization to evaluate traffic
+        in the organizations listed in the `orgs` field.
+        
+        AUTHORIZATION_DIRECTION_TO: Allows the organizations listed in the `orgs`
+        field to evaluate the traffic in this organization.
+        
+        For the authorization relationship to take effect, all of the organizations
+        must authorize and specify the appropriate relationship direction. For
+        example, if organization A authorized organization B and C to evaluate its
+        traffic, by specifying "AUTHORIZATION_DIRECTION_TO" as the authorization
+        direction, organizations B and C must specify
