The Analysis of Propagation Model for Internet Worm Based on Active Vaccination

It is necessary for efficiently controlling Internet worm that the active vaccination by administrators, while the worm vaccination has been a new active defense approach. In this paper, three different types of models, such as running-vacc model, no reboot-vacc model and reboot-vacc model, are explored and analyzed in detail at first, respectively. Secondly, the further analysis for these models are measured through changing parameters of vaccination, which prove that the release rate and release time of vaccine play the key role in the defense. At last, through compare the adaptive environment of three different vaccines, we present basic principles to achieve the actual control of Internet worm.
