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 R 0. It is observed that as R 0 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. • A new model governing DDoS attacks has been proposed to study the virus mobility in targeted network. • Firewall helps to control virus proliferation to a symbolic level by lowering the infection level. • Optimal control theory has been proposed as one more measure for regulating the virus propagation. • Sensitivity analysis is executed that provides information about the virus spread in networks.
