%X Internet worms have severely threatened Internet security. In order to effectively defend against them, it is very important to understand the kinds of scanning strategies and how the scanning strategies affect worm propagation. A simple worm propagation model based on a discrete time differential equation is provided. The different scanning strategies used by Internet worms, such as uniform scan, Hit-list scan, routable scan, divide-and-conquer scan, local subnet scan, sequential scan, permutation scan are analyzed in detail based on the model provided, and given their corresponding models.
