Inconsistency Detection of Authorization Policies in Distributed Component Environment

In distributed component environment, a Role-Based Access Control (RBAC) server manages all authorization policies of components in the same domains whereas the components are distributed to an application server on a network with their authorization policies. It is necessary to detect inconsistency between the authorization policies of the RBAC server and the distributed components to guarantee the authorization policy integrity while system configuration and policies are changing. In this paper, an inconsistency detection method between the two authorization policies is proposed. Conditions of guaranteeing consistency are investigated to detect the inconsistencies and validated in a case study.
