基于攻击意图的工业网络抗毁性评价研究OA

With the rapid development of industrial wireless networks,security incidents are constantly emerging,and network survivability has become one of the focuses of attention in this field.This paper focuses on the security issues in industrial wireless networks,and takes attack intention as the starting point to conduct research on the evaluation of the resilience of industrial wire-less networks.Firstly,by analyzing known attack cases,multiple types of attacks and their potential impacts are identified.Then,different from existing evaluation methods for the characteristics of network systems themselves,a comprehensive survivability e-valuation method is constructed by taking into account the potential intent of the attack.Finally,on an industrial wireless network system model,by comparing it with existing popular network system survivability evaluation methods,it is found that the proposed attack intent based industrial wireless network survivability evaluation method in this paper has a more objective and stable evalua-tion effect.The survivability evaluation method proposed comprehensively considers the intention,probability of occurrence,scope of influence,and possible consequences of external attacks,effectively characterizing the survivability of systems facing the same scale of external attacks in different scenarios.
