Propagation of computer virus under human intervention: a dynamical model. (English) Zbl 1248.68074
Summary: This paper examines the propagation behavior of computer virus under human intervention. A dynamical model describing the spread of computer virus, under which a susceptible computer can become recovered directly and an infected computer can become susceptible directly, is proposed. Through a qualitative analysis of this model, it is found that the virus-free equilibrium is globally asymptotically stable when the basic reproduction number R 0 1 , whereas the viral equilibrium is globally asymptotically stable if R 0 >1. Based on these results and a parameter analysis, some appropriate measures for eradicating the spread of computer virus across the Internet are recommended.
