Research on Simulation of Network Attack and Defense situation based on Evolutionary Game

Network attack and defense research is the focus in the field of network security, but most of the existing network attack and defense studies focus on one of the two sides of attacker and defender, which cannot accurately explain the nature of the attack-defense confrontation. It failed to describe and analyze the game behavior at the micro-level and the network attack and defense scenario at the macro level. Aiming at this, this paper firstly establishes a network attack and defense game model based on evolutionary game theory from the point of view of attack-defense confrontation and studies the quantitative methods of attack-defense income, game equilibrium, and strategic confrontation. Then based on NetLogo and improved SI (Susceptible-Infectious) model, the simulation model of network attack and defense is constructed. Finally, the effectiveness of the proposed model and method is verified by simulation experiments, and the countermeasures and suggestions to enhance the network defense capability are analyzed and summarized from the simulation results.
