In this paper we present Vac, an automatic tool for verifying security properties of administrative Role-based Access Control (RBAC). RBAC has become an increasingly popular access control model, particularly suitable for large organizations, and it is implemented in several software. Automatic security analysis of administrative RBAC systems is recognized as an important problem, as an analysis tool can help designers check whether their policies meet expected security properties. Vac converts

In this paper, we describe the architecture of Vac and overview the analysis techniques that have been implemented in the tool. We also report on experiments with several benchmarks from the literature.
