Security Policy Integration Method for Information Systems

Policy-based security is an effective and convenient approach to manage information systems. By this approach, we can handle easily all behaviors of a system thought a set of rules. However, conflicts between rules are one of the most common problems we have to deal with in administrative process. In this paper, we propose a new axiomatic approach to solve this problem. Several postulates are presented and analyzed as well as some algorithms are proposed next. The algorithms also have been implemented and tested, and experimental results are presented.
