Computer Worm Simulator


According to the latest Microsoft Security Intelligence Report (SIR), worms were the second most prevalent information security threat detected in the first half of 2010 – the top threat being Trojans. Given the prevalence and damaging effects of worms, research and development of worm counter strategies are garnering an increased level of attention. However, it is extremely risky to test and observe worm spread behavior on a public network. What is needed is a packet level worm simulator that would allow researchers to develop and test counter strategies against rapidly spreading worms in a controlled and isolated environment. Jyotsna Krishnaswamy, a recent SJSU graduate student, successfully implemented a packet level worm simulator called the Wormulator. The Wormulator was specifically designed to simulate the behavior of the SQL Slammer worm. This project aims to improve the Wormulator by addressing some of its limitations. The resulting implementation will be called the Improved Worm Simulator.
