University of Texas at San Antonio professor to present two distinguished lectures today and Friday

By Susan Cregg

Ravi Sandhu, executive director and chief scientist at the Institute for Cyber Security and professor of computer science at the University of Texas at San Antonio, will present distinguished lectures both today and Friday on the Kansas State University campus. 

Sandhu's first lecture will be from 4-5 p.m. today in 126 Nichols Hall. His lecture is titled "The Data and Application Security and Privacy (DASPY) Challenge."

This talk will begin by identifying the major challenges in cybersecurity, expressed in a nutshell as “how can we be secure while being secure?” Sandhu will argue that this is the correct goal for us to pursue and that we cannot achieve this goal without bringing in application and technology context. He will then discuss the Policy-Enforcement-Implementation (PEI) paradigm to enable us to address this challenge by divide-and-conquer, and will illustrate this paradigm in a couple of contexts.

Sandhu's second lecture will be part of the first Greater Kansas Area Security Workshop. His lecture, "Group-Centric Secure Information Sharing," will be presented at 9:50 a.m. Friday in the main ballroom of the K-State Student Union.

This talk will give an overview of the concept of group-centric secure information sharing, which is distinguished from traditional dissemination-centric sharing. It will describe policy and enforcement models developed for this purpose, and identify research challenges in this arena. The core metaphor behind groups-centric sharing is a meeting room wherein users and information are brought together for some larger purpose. Agility in sharing requires that such virtual meeting rooms be established and go through their life cycle as driven by end users rather than IT administrators. Security requires that the sharing conform with organizational requirements and policies. The group-centric paradigm is a promising approach to reconcile these conflicting objectives.
