一种基于演化博弈的云分布式入侵检测系统行为分析预测模型

摘要

针对目前云计算环境下分布式入侵检测系统行为分析方法的不足，提出用演化博弈理论构建检测系统行为分析的预测模型，用复制动态方程描绘参与人行为策略选取趋势，用演化稳定策略刻画动态局面的收敛方向，分析讨论了不同损益条件对检测系统行为的影响。在该基础上，给出合理的安全方案，供管理人员参考。最后，设计实验进行分析，验证了该模型的理论，以及预测结果的正确性。%For the lack of distributed IDS behavior analysis method in cloud computing environment, this paper proposes a model based on evolutionary game theory for distributed IDS in cloud behavior analysis and prediction, depict strategy selection trend of participator behavior with replicator dynamics equation, describe convergence trend of dynamic situation with evolutionary stable strategy, and analyse the effect on IDS behavior on different profit and loss condition. Then the paper gives out a reason-able security management suggestion for manager consider. Finally, an experiment is designed over analysis for the model to show the effectiveness of the proposed method.
