In any organization, there are generally several applications in place and usually, each application has its own security policy. In fact, the ability to define multiple security policies is needed in several cases. Moreover, heterogeneous security mechanisms can be used to achieve security objectives. However, implementing a unified security policy for all theses mechanisms becomes then unfeasible. Hence, a formal representation of security policies is needed. Furthermore, since theses policies are generally written by different people, they may have conflicts. The main contribution of this paper concerns then, the formalization of security policies conflicts as well as their detection and resolution.
