I will present a reactive mechanism that protects against network worms and other similar attacks by automatically patching vulnerable software. I will discuss the design, implementation, experimental evaluation, and limitations of the system, as well as our plans for overcoming these. The system is part of SABER, a survivable services architecture developed at the Network Security Lab at Columbia.

Angelos Keromytis has been an assistant professor with the Department of Computer Science at Columbia University since 2001, and director of the Network Security Laboratory. He received his B.Sc. in Computer Science from the University of Crete, Greece, and his M.Sc. and Ph.D. from the Computer and Information Science (CIS) Department, University of Pennsylvania. His current research interests involve around systems and network security, and cryptography. Previous research interests include active networks, trust management systems, and systems issues involving hardware cryptographic acceleration. His recent work has been on survivable system and network architectures.
