When you do that, the policy will grant access and share the resource with others. It is strongly recommended that you enable TLS/HTTPS when accessing the Keycloak Server endpoints. For each request, we don't want to send a request to Keycloak to fetch authorization settings, since they don't change that much.

Allows user's authentication and security with minimum effort. In Keycloak, resource servers are provided with a rich platform for enabling fine-grained authorization for their protected resources, where authorization decisions can be made based on different access control mechanisms. In authorization policy terminology, a scope is one of the potentially many verbs that can logically apply to a resource. All other Keycloak pages and REST service endpoints are derived from this. Considering that today we need to consider heterogeneous environments where users are distributed across different regions, with different local policies, For more information about how to view and test permissions inside your application see Obtaining the authorization context. Example of scopes are view, edit, delete, and so on.
