A Novel Cloud - based Benign Worm Defense Technology ⋆

Due to the proactive defend against the worm propagation and patch the susceptible hosts, benign worms are attracting wide attentions in the field of worm research. In this paper, we point out the errors of worm-anti-worm model (WAW) and present a revised model named Re-WAW based on the law of worm propagation and Two-Factor model. Based on the discussion of the worm propagation factors such as time delay and initial number of benign worms, we put forward a novel cloud-based ReWAW model to achieve effectively worm containment by quickly delivery of the initial number of benign worms. Simulation results show that the cloud-based Re-WAW model significantly improves the worm propagation containment effect relative to the Re-WAW model and Two-Factor model, cloud computing help achieve the rapid delivery of massive initial benign worms and thus obtain close to valuable 20 hours time delay.
