Abstract

Abstract: This paper aims to explore the influence of vaccination on the diffusion of computer viruses under more reasonable assumptions. By incorporating a vaccination probability in the SIRS model with generalized nonlinear incidence rate, a novel epidemic model of computer viruses is established. A thorough analysis of this model shows that, depending on the value of the basic reproduction number, either the virus-free equilibrium or the endemic equilibrium is globally asymptotically stable. Simulation results not only justify the proposed model, but also demonstrate the effectiveness of vaccination. Based on a parameter analysis for the model, some effective strategies for inhibiting the virus prevalence are posed. [Copyright &y& Elsevier]

Abstract

Highlights: [•] This paper addresses the effects of the Internet topology and external computers on computer virus spreading. [•] An epidemiological model is established. [•] The unique (viral) equilibrium of the model is globally attractive. [•] Computers with higher node degrees are more susceptible to infections than those with lower node degrees. [•] Some appropriate protective measures are suggested. [ABSTRACT FROM AUTHOR]
