Abstract

Ever since Melissa struck Microsoft Windows users in late March 1999, computer viruses and worms have become common and persistent. For various practical reasons, many machines remain unprotected by up-to-date software patches or antivirus software, and the Internet's emergence has made it easy to shut down many vulnerable systems either directly or indirectly. In particular, worms have become more prevalent as online connectivity, including always on broadband access, has become ubiquitous.Ironically, emerging high-speed networks will likely accelerate the spread of worms, especially those like Code Red and SQL Slammer. As network rates increase, the time available to respond to worm epidemics may shorten to seconds before the entire vulnerable population is saturated. Defense against such threats will require a comprehensive automated defense.
