中文摘要:随着工业化与信息化的快速交叉融合,工业网络安全问题正在变得越来越严重。针对智能变电站系统的安全场景,分析了智能变电站中的MMS(Manufacturing Message Specification)报文传输的时间特性,并采用傅里叶变换和小波变换的方法对MMS报文传输的时间特性进行更细粒度的分析。通过分析,可以得出一种建立报文传输时间特性基线的方法,用来进行智能变电站系统网络的异常检测。 |

Abstract:With the rapid combination of industrialization and informatization,the issue of the industrial network security is becoming more and more serious. The security problem of the smart substation system is focused on in this paper,and the time features of the MMS packages is analyzed by the Fourier transform and the wavelet transform methods. A method for establishing a baseline of the time features of the MMS packages is obtained to perform abnormal detection of the network in the smart substation system. |
