Role Based Access Control (RBAC) refers to a class of security mechanisms that mediate access to resources through organizational identities called roles. A number of models have been published that formally describe the basic properties of RBAC. One feature of these models is the notion of a role hierarchy, which represents the relationship among roles that are defined in terms of other roles and inherit basic capabilities from them. This paper explores some interesting characteristics of role hierarchies and how they affect basic RBAC properties such as separation of duty.
