Malicious objects propagation dynamics in the network

An attempt is made to develop a discrete-time “Susceptible-Attacked-Infectious-Non-Infectious (SAIN)” model for computer infection with the aim of estimating parameters such as time of attack, incubation time, and mean infection time by using probabilistic approach. SAIN model is basically compartment-specific approach; each compartment is having distinct boundaries. Computer nodes transfers from one compartment to other such as Susceptible to Attacked, Attacked to Infectious, and Infectious to Non-Infectious with some stochastic random variable.
