| Abstract | The threat of Internet worms has been, and continues to be, one of the most important issues faced by networking researchers and network users. The need for accurate and efficient modeling and analysis methods cannot be understated. Models that accurately reflect the behavior of existing and yet-to-be deployed worms is critical to understanding how to deal with this ongoing threat. Recently developed analytical models, have been used to generate propagation trends that match with historic worm outbreaks. However in this effort, the values used for some of the parameters are different from empirically measured information, such as probe rate per unit of IP address space. Although new models are under development, current models lack the ability to predict the effect of future defensive mechanisms, or to react to worm characteristics and network effects such as queuing delay, packet loss, or bandwidth saturation. In our work, we have focused on packet–level detail in the simulation models, which are free from most of these drawbacks at the expense of additional computational complexity. Using our simulator we investigate the limits of one particular analytical model and the reasons behind discrepancies of parameter values. We show how a packet–level worm simulator can be useful in evaluating analytical models, and thus making it an important tool for researchers developing future analytical models. |
