THE IMPACT OF QUARANTINE STRATEGIES ON MALWARE DYNAMICS IN A NETWORK WITH HETEROGENEOUS IMMUNITY

In this paper, we investigate the influence of two types isolation on malware propagation within a computer network. Model 1 proposes network quarantine strategy, where infected computers are fully disconnected from As for model 2, control strategy is anti-virus software quarantine, files in contained an folder. Both models consider aspect heterogeneous immunity, that is, weak and strong immunization Analytical examinations produced virus-free equilibrium endemic each model. It has been observed reproduction number Rq plays essential role existence stability points. Furthermore, numerical simulations accomplished to substantiate qualitative results. Finally, sensitivity analysis executed specify dominant parameters Rq. found performance better than controlling propagation.
