Modelling and Analysis of Propagation Behavior of Computer Viruses with Nonlinear Countermeasure Probability and Infected Removable Storage Media

الملخص EN

The dissemination of countermeasures is diffusely recognized as one of the most valid strategies of containing computer virus diffusion.

In order to better understand the impacts of countermeasure and removable storage media on viral spread, this paper addresses a dynamical model, which incorporates nonlinear countermeasure probability and infected removable storage media.

Theoretical analysis reveals that the unique (viral) equilibrium of the model is globally asymptotically stable.

This main result is also illustrated by some numerical experiments.

Additionally, the numerical experiments of different countermeasure probabilities are conducted.
