智能变电站网络安全态势感知技术

Network security situation awareness technology in smart substation

网络安全态势感知技术在智能变电站中的应用,有助于从更独特、更高层次的安全视角分析评估智能变电站的安全状况。在分析智能变电站安全威胁的基础上,综合物理安全、网络安全、系统安全、协议安全、数据安全等因素提出了一种安全态势感知框架,同时提供了一种变电站网络安全监控方案。即使用专门的智能变电站网络安全态势感知装置收集安全事件的发生情况并对其结果进行分析。此外,描述了设计方案中采用的几个关键技术。最后,提供了智能变电站网络安全态势感知装置的软硬件设计方案。该方案采用多层软件体系结构设计,并使用了英特尔Sandy Bridge处理器、总线结构和模块化设计技术等来满足系统的高性能需求。

On the basis of analyzing the security threats in smart substation, a security situation awareness framework was proposed, combined with integrated physical security, network security, system security, protocol security, data security and so on. And a network security monitoring solution for substations was provided. It was a special intelligent substation network security situation awareness device which could collect the security events,analyze them and generate situation analysis results. Further more, everal key technologies used in our frameworks were focused on. Finally, a design scheme including hardware and software for the smart substation network security awareness system and its implementation architecture were described, in which a multi-layer software architecture was adopted by the system, and a combinatory of the Intel Sandy Bridge, the bus structure and a modular design technology, was adopted in order to meet the need of high performance.
