PLAS - Policy Language for Authorizations

A key issue in authorization services and computer security in general is the definition of security policies [1]. To help define security policies we have developed a new policy language for authorization systems (PLAS), and a framework in which to apply it. This paper describes the PLAS framework and shows how can it be used within current fields of research in IT security such as protection against downloadable code and in intrusion-detection systems.
