Modelling, analysis and containment of passive worms in P2P networks

Abstract

Passive worms continue to pose major threats to the security of internet. In this paper, we tackle the issue by modelling and analysis passive worm propagation which is useful to understand how particular factors can affect their propagation and designing effective containment strategies within P2P networks to suppress worm propagation. In particular: 1) we propose two passive worm mathematic models: a static attack model and a dynamic attack model, and study the sensitivity of worm propagation with various parameters; 2) we conduct a detailed analysis to analyse the attack models and the basic reproduction number R
