On the Accuracy Evaluation of Access Control Policies in a Social Network

Access control policies are mandatory for organizations whose operation involves sharing resources that must be kept private. In this paper, we address the problem of evaluating the accuracy of access control policies distributed in an interaction network modeled from a social network. Such network models granted access to documents owned by a large set of users. Since denied accesses are not included in the input network, we discuss a method based on Network Science to include complementary edges to have an approximate evaluation of ACPs’ accuracy. The synthetic interactions allow the evaluation of ACPs by assessing the explicit and implicit intentions of the owners. We present an evaluation strategy to measure the accuracy of the generated ACPs. The results will be of interest to academics who want to synthesize information for similar phenomena.
