Study on the Policy Conflict Detection in the Security Management Model

Through using the concept of deontic logic and classifying different types of policy conflicts, an effective policy conflict detection method was proposed. The main idea of the method is based on the research on the existing policy conflict detection methods. Then, a powerful conflict library in the detection process is built. The library is combined with the static and dynamic detection of policy conflicts, and thus is able to supervise the running state of the management system. Therefore, the proposed method can precisely detect policy conflicts during the run-time of the management system.
