基于M-FlipIt博弈模型的拟态防御策略评估

Evaluation of mimic defense strategy based on M-FlipIt game model

针对先进持久性威胁场景中模拟防御系统安全性能评估的不足,基于FlipIt博弈论模型,提出了一种改进的博弈模型。对不同的异构性条件下的拟态防御动态策略进行评估,并设计案例进行仿真分析。仿真结果表明,不定周期的轮换能够弥补异构性的不足,维持防御者较高的博弈收益。

To make up for the lack of security performance evaluation of the mimic defense systems in the advanced persistent threat scenarios an improved game model based on the FlipIt game theory model was proposed.The dynamic strategy of mimic defense under different heterogeneity conditions was evaluated,and a case study for the simulation analysis was conducted.The simulation results show that the rotation of indefinite period can make up for the lack of heterogeneity and maintain the higher game payoff of defenders.
