The Chinese Wall model is a model of a security policy that refers equally to confidentiality and integrity. In this paper, we propose a Colored Petri net modeling technique, which allows one to analyze and verify Chinese Wall Policy in Colored Petri net model of a system. Subsequently, an example of the Chinese Wall Policy is illustrated and the conclusions show that Petri net is not only a concise graphic modeling method, but also suited to formal analysis and verification. This technique can efficiently improve the security policies during the system design and implementation.
