Role-based Access Control (RBAC) models have been implemented not only in self-contained resource management products such as DBMSs and Operating Systems but also in a class of products called Enterprise Security Management Systems (ESMS). ESMS products are used for centralized management of authorizations for resources resident in several heterogeneous systems (called target systems) distributed throughout the enterprise. The RBAC model used in an ESMS is called the Enterprise RBAC model (ERBAC). An ERBAC model can be used to specify not only sophisticated access requirements centrally for resources resident in several target systems, but also administrative data required to map those defined access requirements to the access control structures native to the target platforms. However, the ERBAC model (i.e., the RBAC implementation) supported in many commercial ESMS products has not taken full advantage of policy specification capabilities of RBAC. In this paper we describe an implementation of ESMS called the 'Role Control Center' (RCC) that supports an ERBAC model that includes features such as general role hierarchy, static separation of duty constraints, and an advanced permission review facility (as defined in NIST's proposed RBAC standard). We outline the various modules in the RCC architecture and describe how they collectively provide support for authorization administration tasks at the enterprise and target-system levels.
