Cyber攻击下韧性信息服务云环境能力评估

Evaluating the capability for resilient information service cloud environment under cyber attack condition

现代快速多变、不确定、Cyber对抗激励的战场环境对军事信息服务云环境的韧性能力提出了更高的要求,提出了一种Cyber攻击下韧性信息服务云环境能力评估方法。首先明确了韧性信息服务云环境的概念,分析了信息服务云环境韧性过程和要素,建立了Cyber攻击下云环境"四阶段"韧性过程模型;其次,从吸收扰动能力、恢复能力、适应能力3方面,建立了能力降级率、抗毁顽存时间、异常识别率、异常识别时间、能力恢复率、任务完成波动率等3类共15项韧性能力度量指标体系,建立了韧性能力指标评估计算模型。最后,以韧性信息服务云环境的指挥引导任务为案例,开展不同引导资源毁伤条件下指挥引导任务完成波动率的仿真实验,韧性评估结果可为提升韧性能力提供参考依据。

The rapid,changeable and uncertain modern battlefield environment has put forward higher requirements for the resilience of the military information service cloud environment,due to which an assessment method for the cloud environment capability of resilience information service under cyber attack condition is proposed.Firstly,the concept of resilient information service cloud environment has been clarified,the resilient process and elements of information service cloud environment are analyzed,and the four-phase toughness process model of cloud environment under cyber attack is established.Secondly,15 resilience indexes are established from three aspects of absorbing disturbance capacity,recovery capacity,and adaptability,including capacity degradation rate,invulnerability and stubbornness time,abnormal recognition rate,abnormal identification time,ability recovery rate,and mission completion fluctuation rate,and the capability evaluation model is established.Finally,scenario-based case studies that involve the command and guidance task of resilience information service cloud environment,the simulation experiments of the mission completion fluctuation rate of command and guidance tasks are carried out under different guidance resource damage conditions.The assessment results can provide reference for improving resilient capacity.
