A worm counter-measurement strategy in P2P networks: Modeling and analysis

As a new active countermeasure, the technology of worm-anti-worm has great potentiality in worm defense, and has gradually become a hotspot of network security. This paper proposes two strategies to defend against malicious worm based on benign worm; develops two worm-anti-worm models based on different attack strategies combining the dynamic characteristics of P2P worm propagation, assesses the key parameters to affect the propagation speed of malicious worm. The numerical analysis on the proposed strategy indicates that our solution can slow down the spreading speed of malicious worms dramatically by employing benign worms, prevent the transmission of malicious worms in P2P networks efficiently. We believe our work provides useful guidance for defending against worms in P2P networks.
