This paper reports the results of our experimentation with modeling worm behavior on a large scale, fully adaptable network simu- lator. Our experiments focused on areas of worm scanning methods, IP address structure, and wireless links that, to the best of our knowledge, have been mostly neglected or abstracted away in prior worm simula- tions. Namely, our intent was to first study by direct observation of our simulations the effects of various IP scanning techniques on the effective- ness of worm spread. Second, our intent was to research the effects that having a larger IP address space (specifically a sparsely populated IP ad- dress space like that provided by Internet Protocol Version 6) would have on the effectiveness of several worms. Third, we study how the wireless media may affect the propagation of worms. In order to perform these simulations we have made use of the Georgia Institute of Technology’s network simulator, GTNetS, extending the worm classes packaged with the simulator. 1 Introduction The propagation of Internet worms has a devastating effect on the normal oper- ations of the Internet. Because of the cost of worm attacks, mu
