Abstract:
In this work we have presented firstly a translation of policy documents those written in extended XACML into OWL-DL and then described how those translations can be used for policy analyzing and matching by exploiting OWL reasoner functionalities. As a reasoner we have exploit Hermit reasoner capabilities. We have provided some background knowledge about XACML, extended XACML and OWL to make clear the problem and suggested solution. We believe that, this approach can be used to help developing security frameworks for dynamic environments which require an agreement before sharing data. Policy Matching application would be useful in several fields in which access control is main issue. Its flexible structure enables to adapt to the application domain easily and cover all necessary access control problems. We have demonstrated that representing policies with OWL has several advantages: Firstly most policy languages define constraints over classes of targets, objects, actions, time etc. which can be defined easily with OWL. Secondly OWL's logic facilities enable to translate of policies expressed in OWL to other formalisms either for analysis or for execution. Moreover OWL reasoning capacity allows users manage and solve policy conflicts in an automated, error free way particularly in hierarchical issues and in multi-organizational environments.
