摘要:

针对网络攻防对抗中的安全防御策略选取问题,研究攻防双方策略相互影响的动态变化过程。从攻防双方的博弈过程出发,构建攻防博弈模型,基于蒙特卡洛模拟法模拟攻击者的攻击过程,得到攻击者的最佳攻击效用,进而计算防御者的最佳防御效用。该方法实现了在有限的资源投入下选取最优的防御策略,以达到网络安全防御效用的最大化。仿真实验验证了该方法的有效性,并分析了不同参数设置对防御策略选取的影响。

Abstract:

Aiming at the selection of security defense strategy in network attack-defense,the dynamic change process of mutual influence between attack-defense strategy was studied.Based on the game process of both offense and defense,the attack-defense game model was constructed,the attack process of the attacker based on Monte Carlo simulation was simulated and the attacker’s best attack utility was obtained,so as to calculate the best defensive utility of the defender.In order to maximize the effectiveness of network security defense,the optimal defense strategy under limited resources was implemented.Simulation experiments verify the effectiveness of the proposed method and analyze the influence of different parameter settings on the selection of defense strategy.

Key words: attack-defense game, defense strategy, Monte Carlo simulation, utility function
