Abstract
In this paper, we simulate the Code Red II and Nimda worms on different
enterprise-scale networks to determine the impact that topology has
on worm propagation. A corporate network can be designed to improve
security and, as we show, to decrease the propagation rate of worms
that use network scanning as a target discovery technique. We also
examine the impact that LaBrea-like devices have on propagation
rates and compare it to the impact of network topology.
