Symantec Computer Virus and Worm Simulation System

The VBSim program is a malware simulation that demonstrates how a computer virus or worm spreads inside and between corporations. The simulation relies upon user-specified parameters, probability functions, and random numbers to model the corporate environment. Because it is a simulation, different outcomes and different infection patterns are generated each time the program runs. The infection patterns can vary widely from one run of the program to another. Although the parameters that have been chosen and the mathematical models used within the simulation are not perfect, they do model the gross behavior of computer viruses and worms. Because this is a simulation governed entirely by random processes, its behavior may not always conform to your expectations. Over many runs of the simulation, however, trends and behaviors will emerge. VBSim was first demonstrated at the 1999 Virus Bulletin conference in Vancouver, Canada. The Symantec AntiVirus Research Center continues to update and work with models such as VBSim to help advance antivirus research.
