Abstract:

In the first part of my talk, I will present the Crossfire attack – a powerful attack that degrades and often cuts off network connections to a variety of selected server targets (e.g., servers of an enterprise, a city, a state, or a small country) byflooding only a few network links. In Crossfire, a small set of bots directs low intensity flows to a large number of publicly accessible servers. The concentration of these flows on the small set of carefully chosen links floods these links and effectively disconnects selected target servers from the Internet. The sources of the Crossfire attack are undetectable by any targeted servers, since they no longer receive any messages, and by network routers, since they receive only low-intensity, individual flows that are indistinguishable from legitimate flows. The attack persistence can be extended virtually indefinitely by changing the set of bots, publicly accessible servers, and target links while maintaining the same disconnection targets.



Bio:

Soo Bum Lee is a Research Systems Scientist for CyLab at Carnegie Mellon University. He received his Ph.D. and M.S. in Electrical and Computer Engineering from the University of Maryland College Park, and M.S. and B.S. in Electrical Engineering from Yonsei University, Seoul, Korea. He was a senior research engineer in LG Industrial Systems from 1997– 2003, where he developed Distributed Control Systems (DCS). Soo Bum Lee’s current research focuses on next-generation secure and available networks and network Distributed Denial-of-Service (DDoS) defense mechanisms.
