Modeling virus and anti-virus dynamics in topology-aware networks

Abstract

Viruses propagating over the Internet can result in significant damage and the loss of network security. On the other hand, the anti-virus process is already a part of the virus spreading process and plays an important role affecting the dynamics of the virus spreading. The spreading dynamics of most viruses depend upon the underlying network topology. While much research effort has been paid in the development of the anti-virus software/tools, the dynamics and propagating model of the virus and anti-virus spreading in the topology-aware networks is neither well understood, nor thoroughly investigated. To remedy this deficiency, we propose the two-layer small-world network topology to model the spreading characteristics of viruses as coexisting with the anti-virus spreading process. The simulation experiments verify the analytical results in characterizing both the virus and antivirus spreading dynamics. © 2004 IEEE.
