Mathematical Model on Attack of Worm and Virus in Computer Network

To curb the impact and transmission of worms and virus for simple mass action incidence rate in computer networks, SI1I2RS (Susceptible, Infectious due to worm, Infectious due to virus, Recovered and Susceptible) model have been formed. Basic reproduction number, endemic equilibrium state and their stability are discussed for the simple mass action incidence. For locally and globally asymptotically stability of the infection free equilibrium state, Liapunov function is used. Numerical methods have been used to solve and simulate the system which will help us to understand the attacking behavior and transmission dynamics of malicious object in computer network, and efficiency of antivirus software.
