An innovative simulation environment for cross-domain policy enforcement

An Innovative Simulation Environment for Cross-Domain Policy Enforcement Lifeng Wang, Zhengping Wu Department of Computer Science and Engineering University of Bridgeport, Bridgeport, CT Policy-based management is necessary for cross-domain organization collaborations and system integrations. In reality different systems from different organizations or domains have very different high-level policy representations and low-level enforcement mechanisms. To ensure the compatibility and enforceability of one policy set in another domain, a simulation environment is needed prior to actual policy deployment and enforcement code development. The goal of this paper is to propose an enforcement architecture and develop a simulation framework for cross-domain policy enforcement. The entire environment is used to simulate the problem of enforcing policies across domain boundaries when permanent or temporary collaborations have to span multiple domains. The middleware derived from this simulation environment can also be used to generate policy enforcement components directly for permanent integration or temporary interaction.
