Abstract: In this paper, a model with two different frameworks of an attacking class and a targeted class is introduced to study the virus mobility of an attack in a targeted network. Existence and stability of equilibrium points are discussed in equivalence with the basic reproduction number R0. It is observed that as R0 crosses unity, transcritical bifurcation arises in the system. The effect of firewall security is also shown graphically which has been taken as a media coverage factor in this work and it is discovered that firewall helps to bring down the virus propagation by reducing the infection peak. Optimal control concept is then introduced to propose one more measure for regulating the virus propagation. Numerical experimentations have been done to rationalize the analytical conclusions. In the end, a sensitivity analysis is executed that provides the information about relevance of parameters in deciding the virus spread in networks.
