A COMPREHENSIVE APPROACH FOR SOLVING POLICY HETEROGENEITY

Rodolfo Ferrini, Elisa Bertino

Abstract

With the increasing popularity of collaborative application, policy-based access control models have become the usual approach for access control enforcement. In the last years several tools have been proposed in order to support the maintenance of such policy-based systems. However, no one of those tools is able to deal with heterogeneous policies that is policies that belong to different domains and thus adopting different terminologies. In this paper, we propose a stack of function that allow us to create a unified vocabulary for a multidomain policy set. This unified vocabulary can then be exploited by analysis tools improving accuracy in the results and thus applicability in real case scenarios. In our model, we represent the vocabulary of a policy adopting ontologies. With an ontology it is possible to describe a certain domain of interest providing richer information than a plain list of terms. On top of this additional semantic data it is possible to define complex functions such as ontology matching, merging and extraction that can be combined together in the creation of the unified terminology for the policies under consideration. Along with the definition of the proposed model, detailed algorithms are also provided. We also present experimental results which demonstrate the efficiency and practical value of our approach.
