Towards context-aware security: an authorization architecture for intranet environments

Abstract

We introduce a context-aware authorization architecture that is designed to augment existing network security protocols in an intranet environment. It describes the architecture components, the proposed extensions to RBAC that facilitate context-aware access control policy, details of the prototyped implementation, and a number of performance results.
