Current Role-Based Access Control (RBAC) can't assign permissions dynamically and can't update access control policies automatically. In this paper we present a new network access control (NAC) mechanism based on role and behavior (RB-NAC) which enhances role-based access control by establishing clusters of behavior to limit permissions of user dynamically(More)
Evolutionary approaches have been used in a large variety of design domains, from aircraft engineering to the designs of filters. An alternative approaches to the design of digital filter have been proposed using evolutionary algorithms and the concept of Evolvable Hardware. In this paper, clustering and Pareto optimization are combined into a single(More)
