摘要
随着核电行业生产模式的智能化,其面临的网络安全威胁日益增多。基于5G新技术带来的时空特性,在5G核电网络环境下,提出了基于时空关联的网络安全态势感知方法,采用Endsley SA改良模型的网络态势感知、网络态势理解、网络态势预测和网络态势可视化4个阶段,基于层次化的网络安全态势分析策略,从底层向上评估整体的网络安全态势;同时在时间维度上,基于时间序列预测分析,在空间维度上,采取基于空间数据挖掘理论的安全态势空间维度分析算法,预测网络未来的安全态势。针对5G核电网络安全态势感知给出了解决方案,提升了核电行业的网络安全能力。
With the intelligentization of the production mode of the nuclear power industry,the cyber security threats to nuclear power increase rapidly.According to the spatiotemporal characteristics brought by new 5G technology,a network security situation awareness method based on space-time correlation is proposed under 5G nuclear power network environment.The four stages of network situation awareness,network situation comprehension,network situation prediction and network situation visualization of the improved Endsley SA model are applied.Based on the hierarchical network security situation analysis strategy,the overall network security situation is evaluated from the bottom up.At the same time,in time dimension,the prediction and analysis is carried out based on the time series.And in spatial dimension,the security situation space dimension analysis algorithm based on the spatial data mining theory is adopted to predict the future security situation of the network.And a solution is provided for 5G nuclear power network security situation awareness,which improves the network security capabilities of the nuclear power industry.
