CS Colloquium: Amy Babay (Johns Hopkins University) - Dependable Systems and Networks for a Complex World

Speaker: Amy Babay, Johns Hopkins University

Talk Title: Dependable Systems and Networks for a Complex World

Series: CS Colloquium

Abstract: As our world grows more complex, the expectations we place on the networked systems running our society's infrastructure grow more demanding. In this talk, I will discuss two types of emerging demands and present infrastructure systems we have developed to meet those demands. The first part of the talk will focus on the demanding performance requirements brought by emerging highly interactive applications such as remote robotic manipulation, remote surgery, and collaborative virtual reality. These applications require communication that is both timely and highly reliable, but the Internet natively supports only communication that is either completely reliable with no timeliness guarantees (e.g. TCP) or timely with only best-effort reliability (e.g. UDP). We present an overlay transport service that can provide highly reliable communication while meeting the stringent timeliness requirements of these applications. The second part of the talk will address the demanding security and resilience needs of critical infrastructure services, in particular SCADA systems for the power grid, that are increasingly becoming exposed to malicious attacks. I will present our work building Spire, the first intrusion-tolerant SCADA system for the power grid that is resilient to both system-level compromises and sophisticated network-level attacks.

This lecture satisfies requirements for CSCI 591: Research Colloquium.

Biography: Amy Babay recently completed her PhD in Computer Science at Johns Hopkins University, where she was a member of the Distributed Systems and Networks Lab. Her research focuses on enabling new Internet services with demanding performance requirements and on building dependable critical infrastructure systems. Prior to starting her PhD, she gained experience with global overlay networks in the commercial world, working at LTN Global Communications. She is currently working to advance some of her research toward commercialization at Spread Concepts LLC.
