ABSTRACT
As laptops and other portable computing devices become ubiquitous, questions of security policy arise that need to be addressed. It is possible for a computer to visit, in the sense of a local attachment to network resources, a domain far (in both geographical and administrative senses) from its home. The visited domain may trust the visitor implicitly, not at all, or somewhere in between. The visitor may view the visited domain as friendly, as benign, or as hostile to varying degrees. The visitor may use the facilities of the visited domain solely to provide connectivity to the outside world or may use various resources within it. Its own resources may be shared or may require protection. The mobile security group at Portland State has built a system based on an integration (or perhaps "shotgun marriage") of the emerging IETF standards for IP mobility and IP security which provides an environment in which to explore these policy issues. The talk will describe the system and develop a taxonomy of policy considerations that should form a basis for future work in policy definition and flexible policy enforcement. 

About John McHugh
Tektronix Professor, Computer Science Department, Portland State University 

John McHugh is a professor and former chairman of the Computer Science Department at Portland State University in Portland, Oregon where he holds a Tektronix Professorship. His research interests include computer security, software engineering, and programming languages. He has previously taught at the University of North Carolina and at Duke University. He has been an active researcher in the application of formal methods to the construction of dependable and secure systems for many years. Dr. McHugh received his Ph.D. degree in computer science from the University of Texas at Austin. He has an MS degree in computer science from the University of Maryland, and a BS degree in physics from Duke University. He grew up in Durham, North Carolina, leaving when he graduated from Duke. Twenty years later, he returned, demonstrating that Thomas Wolfe was wrong. After another ten years in Durham, he moved to Portland, demonstrating, perhaps, that Wolfe knew what he was talking about after all.
