面向控制平台的异常监测系统的设计与实现

Design and Implementation of Abnormal State Detection System for Control Platform

由于工业控制系统信息安全问题日趋严峻,国内在工业控制系统信息安全方面的异常监测技术研究仍处于起步阶段,因此,本文以具体的工业控制系统——IAP控制平台作为研究对象,从控制组态监控、操作指令监控、网络通信流量监测等方面设计了异常监测系统,包含了系统的硬件架构设计、软件结构设计,同时,将该系统在IAP控制平台上进行了验证和测试。结果表明,该系统在不影响整个IAP控制平台正常运行的情况下能有效监测工业控制系统中的异常行为及流量。

The cyber security problem of industrial control system becomes increasingly serious, abnormal detection technology in domestic is still at an initial stage, thus, this paper regards the specific industrial control system—Industrial Automation Platform as the object of this research. Abnormal state detection system is designed from the aspect of control configurations, operational instructions and network traffic. Designs of hardware architecture and software structure have been included. The system is simulated and tested on Industrial Automation Platform（IAP）. The result shows that the system can monitor abnormal state and traffic effectively. Moreover, it doesn＇t affect the availability of the whole platform.
