Rules Overview

Rules identify specific resources and either allow or deny access to the resources. Rules can also be used to trigger responses when authentication or authorization events take place. When you create rules, you must associate rules with specific realms.

The following diagram illustrates a number of realms and nested realms and their associated rules.

In the diagram above, different realms and nested realms have specific rules associated with the resources in the realm. It is also possible to have a single rule associated with all of the resources in a realm, or a subset of resources in the realm. This is done by using resource matching or regular expressions to specify resources.
