【摘要】 为实现电力系统视频监控系统中网络安全的有效管理，分析了电力监控系统安全防护的需求，结合电力二次系统安全防护的特点，提出一种电力监控系统的安全威胁溯源方法。该系统主要是根据告警日志构建相应的树状发生树，并对其进行聚合、断链处理，进而获取事件发生链合集。测试结果显示，此种方法能够有效分析电力监控系统告警数据，有助于网络管理者实时监测网络安全状态，及时做出相应的安全防范措施，对于提升网络的安全性有着十分重要的作用。更多还原

【Abstract】 In order to achieve effective management of network security in the video surveillance system of the power system,the requirements for security protection of the power monitoring system were analyzed. Combined with the characteristics of security protection in the secondary power system, a security threat tracing method for the power monitoring system was proposed. The system mainly constructs a corresponding tree like occurrence tree based on alarm logs, aggregates and breaks the chain, and then obtains a collection of event occurrence chains. The test results show that this method can effectively analyze the alarm data of the power monitoring system, which helps network managers to monitor the network security status in real time, and make corresponding security measures in a timely manner. It plays a very important role in improving the security of the network.更多还原
