Abstract:

Network attack-defense confrontation is essentially a game process between the non-equal subject of attack and defense. In the research of the existing network defense strategy, there is a priori hypothesis defect of equal status between the subjects of the attack and defense game. Game theory is introduced into the process of constructing network defense strategy generation model, and a dynamic defense strategy generation method based on Stackelberg security game is proposed. By establishing the network model, the Stackelberg security game strong equilibrium strategy algorithm is used to generate the optimal defense strategy, which not only fully considers the influence of the relationship between the two sides in the attack and defense behavior, but also ensures the accuracy of the defense strategy generation. The experimental results show that the proposed model and method are feasible and effective, and can enhance the security of the system.
