Abstract:
Information security system is an important problem in many domains. Therefore, it is very important to define security policies to restrict access to pieces of information in order to guarantee security properties, i.e. confidentiality, integrity and availability requirements. The joint handling of confidentiality, integrity and availability properties raises the problem of potential conflicts. The objective of this paper is to propose tools, based on the argumentation reasoning, for handling conflicts in prioritized security policies.
