Using a new technique, University of California, San Diego network researchers from the San Diego Supercomputer Center [SDSC] and the Jacobs School of Engineering have analyzed the worldwide pattern of malicious denial-of-service [DoS] attacks against the computers of corporations, universities, and private individuals. The attacks disable Web servers on the Internet by overloading them with messages, which usually contain false source addresses to conceal the locations of the attackers. But in a clever twist, the researchers used key features of these messages' forged signatures to detect and track the attacks.

"We believe that our research provides the only publicly available data quantifying denial-of-service activity in the Internet," said David Moore, a senior researcher in UCSD's Cooperative Association for Internet Data Analysis [CAIDA] program at SDSC. Moore and UCSD Computer Science and Engineering professors Geoff Voelker and Stefan Savage have devised a new technique called "backscatter analysis" that gives an estimate of worldwide denial-of-service activity. Their research enables network engineers to understand the nature of recent attacks and to study long-term trends and recurring patterns of attacks.
