Virus Propagation Model and Node Defense Strategy of Single Operation System Virus

In view of the characteristic of single operation system virus which can only infected the special operation system, the virus propagation mechanism and corresponding node defense strategy is studied. In this paper, taking Windows virus as the research object, the virus propagation model of single operation system virus is constructed based on the SIR model to study the single operation system virus propagation mechanism. to promote network security, the node defense strategies, operation system switching frequency adjustment strategy and operation system scaling strategy, are proposed. The simulation results show that the proposed node defense strategy can effectively inhibit the spread of single operation system virus.
