Research on Strategy Selection of Dynamic Defense Based on Game Theory

Aiming at the optimal selection of transition cycle in the design of dynamic defense strategy, this paper studies the dynamic change process of the interaction between attack and defense strategies by using game theory. Starting from the game process of attack and defense, this paper constructs the attack and defense game model, simulates the attack process of the attacker, obtains the best attack decision of the attacker, and then calculates the best defense income of the defender. This method can select the optimal defense strategy under the limited dynamic defense technology deployment, to maximize the network security defense revenue. Simulation results verify the effectiveness of the method and quantitatively analyze the improvement level of the dynamic defense technology optimal strategy compared with the traditional static defense technology.
