Developing Pervasive Trust Paradigm for Authentication and Authorization

Traditionally, authentication and authorization (A&A) in computer systems guard only user interfaces, thus providing only a perimeter defense against attacks. We search for an A&A approach that satisfies the requirements of multiple lines of defense and defense in depth. After reviewing and classifying a variety of security paradigms, we propose the paradigm of pervasive trust. It is analogous to a social model of interaction, where trust is constantly --if often unconsciously-- applied. In an initial study performed in our lab, we investigate using trust for the perimeter-defense A&A model, in which the capability to use trust ratings for users was applied for enhancing the role-based access control mechanism.

Dr. Leszek Lilien received his Ph.D. in Computer Science from the University of Pittsburgh. His research at Purdue University concentrates on trusted computing and computer security.
