The propagation of P2P worm covers large area and causes great damage. A dynamic quarantine protocol is designed to quarantine the suspicious host in the P2P system. Then a mathematical model of PWPQ is proposed which considering the dynamic process of peer joining and leaving. The effect of dynamic quarantine on active P2P worm is analyzed. Through stability analysis for PWPQ model, a key argu...

To detect and defend against Internet worms, researchers have long hoped to have a safe convenient environment to unleash and run real-world worms for close observation of their infection, damage, and propagation. However, major challenges exist in realizing such “worm playgrounds”, including the playgrounds’ fidelity, confinement, scalability, as well as convenience in worm experiments. In thi...

With increasing speed, virulence, and sophistication, self-propagating worms continue to pose a serious threat to the safety of the Internet. To effectively identify and defend against self-propagating worms, a critical task is to characterize a worm along multiple dimensions. Content-based fingerprinting is a well-established dimension for worm characterization by deriving the most representat...
