Protecting federated databases using a practical implementation of a formal RBAC policy \ud

By Steve Barker and Paul Douglas

Abstract

This paper describes the use of formally specified RBAC\ud policies for protecting federated relational database systems that are accessed over a wide area network. The\ud method that is described combines a formally specified\ud RBAC policy with both temporal and locational constraints.\ud It does not depend on any security mechanism supported by\ud a specific DBMS and is thus portable across platforms.\u
