Chinese Wall security model and conflict analysis

D.D.C. Brewer and M.J. Nash (IEEE Symposium on Security and Privacy, pp. 206-14, 1988) introduced Chinese Wall security policy models for commercial security. These were later updated by T.Y. Lin (Proc. 5th Aerospace Comput. Security Appl. Conf., pp. 286-93, 1989). Applying Z. Pawlak's (1997) idea of conflict analysis, this paper introduces a practical way of computing an extended model.
