Security Policy Conflict Detection for Distributed System
Distributed applications require integrating security policies of collaborating parties, and the policies must be able to support complex authorization specifications and conflicts of policies must be able to be detected. In this paper, we introduce a policy for fine-grained access control which is able to support the specifications with sufficient policy constraints, and then we present a methodology based on semantics to detect whether there are policy conflicts and then produce the XACML policy document.
