### A Quarantine Model for Malicious Objects in Computer Network

#### Abstract

With a view to protect computer network from malicious object, SEIQS (Susceptible, Exposed, Infectious,Quarantined and Susceptible) models for the transmission of malicious objects with simple mass action incidence and standard incidence rate in computer network are formulated. Threshold,equilibrium and their stability are discussed for both the incidence rate. Global stability and asymptotic stability of endemic equilibrium has been shown. Numerical methods have been used to solveand simulate the system of differential equations which will help us to understand the attacking behavior of malicious object in computer network.
