Abstract
NATO is developing a new IT infrastructure for automated information sharing between different information security domains and supporting dynamic and flexible enforcement of the need-to-know principle. In this context, the Content-based Protection and Release (CPR) model has been introduced to support the specification and enforcement of NATO access control policies. While the ability to define fine-grained security policies for a large variety of users, resources, and devices is desirable, their definition, maintenance, and enforcement can be difficult, time-consuming, and error prone. In this paper, we give an overview of a tool capable of assisting NATO security personnel in these tasks by automatically solving several policy analysis problems of practical interest. The tool levarages state-of-the-art SMT solvers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
