Abstract

This paper proposes a simulation model to characterize virus propagation in an email network and analyzes various defense strategies. We demonstrate the key factor which affects the efficiency of different strategies, and illustrate two phases of virus propagation. The results show that D-steps immunization is a feasible strategy in the case of finite resources and the efficiency of node-betweenness immunization is better than targeted immunization if we have the global information about a network.
