-
-- `Security Reader`
-- `Reader`
+Regarding the subscription scope, Prowler by default scans all subscriptions that it is able to list, so it is necessary to add the `Reader` RBAC built-in roles per subscription or management group (recommended for multiple subscriptions, see it in the [next section](#recommendation-for-multiple-subscriptions)) to the entity that will be adopted by the tool:

-Moreover, some additional read-only permissions are needed for some checks, for this kind of checks that are not covered by built-in roles we use a custom role. This role is defined in [prowler-azure-custom-role](https://github.com/prowler-cloud/prowler/blob/master/permissions/prowler-azure-custom-role.json). Please be sure to change the `assignableScopes` field for your subscriptions or management group. Once the cusotm role is created, repeat the steps mentioned above to assign the new `ProwlerRole` to an identity.
