Due to the rapid spreading nature of Internet worms, it is necessary to implement automatic mitigation on the Internet. Inspired by worm vaccinations, we propose a novel epidemic model which combines both vaccinations and dynamic quarantine methods, referred to as SEIQV model. Using SEIQV model, we obtain the basic reproduction number that governs whether or not a worm is extinct. The impact of different...
Passive worms have posed serious security threats to unstructured P2P networks. A delayed SEIRS epidemic model with death, offline and online rate is constructed based on the actual situation of P2P users. The basic eproduction number that governs whether a passive worm is extinct or not is obtained. In this model, time delay consists of latent and temporary immunity periods. The impact of different...
