基于博弈模型与NetLogo仿真的网络攻防态势研究

Research on Network Attack and Defense Situation Based on Game Theory Model and NetLogo Simulation

针对现有建模方法缺乏对攻防博弈行为与态势演化趋势的分析问题,从对抗角度出发分析网络攻防博弈特征;基于非合作不完全信息静态博弈理论建立网络攻防博弈模型,给出收益量化、博弈均衡计算和策略对抗结果判定方法;构建网络攻防博弈多Agent仿真模型;采用NetLogo开展局中人不同策略组合、不同初始数量等场景下的仿真实验,得出网络攻防态势随时间演化情况,通过对比分析仿真结果,给出扭转网络攻防态势的建议。

Aiming at the problem that the existing modeling methods lack of the analysis on the behavior and trend of attack and defense game,the characteristics of network attack and defense game from the perspective of confrontation are analyzed Based on the static game theory of non-cooperative incomplete information,the network attack and defense game model is established,and the revenue quantification,game equilibrium calculation and decision-making of strategic confrontation result are given.The multi-agent simulation model of network attack and defense game is constructed.The simulation experiments under different strategy combinations and different initial numbers of players are carried out by using Netlogo.The evolution of network attack and defense situation with time is obtained.By comparing and analyzing the simulation results,some suggestions are given to reverse the network attack and defense situation.
