基于智能Agent的电力信息网络安全态势感知模型研究

Research on Electric Information Network Security Situation Awareness Model Based on Intelligent Agent

网络安全态势感知(NSSA)是实现网络安全监控的一种有效的技术手段,对提高网络运行安全管控水平和主动防御能力有着重要的作用。在现有的NSSA模型研究的基础上,结合电力信息网络的现状与需求,提出了一种基于智能Agent的NSSA感知模型。模型从数据采集处理层、评估分析层、协调管理层和态势决策层几个层次介绍了涉及的Agent模型和功能模块,对电力信息网络安全监控和管理具有一定的指导意义。

Network security situation awareness（NSSA） is one of the effective ways to implement network security monitoring.It can be utilized to improve the operational security management and to enhance the proactive defense ability of the network.On the basis of the research work on NSSA models,a NSSA model based on intelligent agent was proposed with the consideration of current situation and demand of electric information network.With the aim of directing the security monitoring and management of electric information network,the proposed model describes the agent modeling and functional modules of four layers that are data collection and processing layer,evaluation and analysis la-yer,coordination and management layer and situation decision layer.
