摘要
为了对DDoS攻防行为进行有效评估以防御DDoS攻击,本文首先对DDoS攻防评估研究现状进行了分析,然后基于随机Petri网建立了DDoS攻防行为对抗网,提出了以攻防稳态概率作为攻防行为评估的依据,紧接着基于攻防博弈提出了攻防博弈策略求解方法,最后对本文所建立的DDoS攻防行为对抗网进行稳态分析并综合考虑攻防行为收益和攻防行为强度两方面因素进行了仿真评估,评估结果表明本文方法更具合理性和针对性.
In order to effectively evaluate DDoS attack and defense behavior to defend against DDoS attacks,this study first analyzed the current research status of DDoS attack and defense evaluation,and then established DDoS attack and defense behavior confrontation net based on stochastic Petri net.The attack and defense steady state probability is used as the basis for the evaluation of attack and defense behavior.The solution of attack and defense game strategy based on the attack and defense game theory were proposed.In the end,we carried out the stability analysis of the DDoS attack and defense behavior confrontation net,and comprehensively considered the factors of attack and defense behavior gain and attack and defense behavior intensity to simulate and evaluate.The evaluation results show that the method is more reasonable and pertinent.
