Embodiment 1

[0025] Such as figure 1 As shown, this solution provides a DCS flow processing method, which includes:

[0026] Step S1, obtaining DCS traffic of the DCS system from a mirror port of a switch connected to the DCS system.

[0027] Specifically, the DCS system presented in this article is a distributed control system (Distributed Control System), and the DCS flow can be the data flow generated by the communication between various components in the DCS system, for example, the communication between the transmitter and the controller in the DCS system Data traffic generated by communication. to combine Figure II , the DCS system is connected to a switch. In this solution, an industrial control network traffic audit module (which can be a server) is connected to the switch, and then the DCS traffic of the DCS system is obtained through the mirror port of the switch. It should be noted that this solution It is to set up an industrial control network traffic audit module separate...

Embodiment 2

[0076] Such as Figure 4 As shown, this solution provides a DCS traffic processing device, the device includes:

[0077] The obtaining unit 40 is used to obtain the DCS flow of the DCS system from the mirror port of the switch connected to the DCS system; the analysis unit 42 is used to analyze the DCS flow to obtain a plurality of DCS bits in the DCS system point; the first determination unit 44 is used to determine the site to be alarmed from the plurality of DCS sites according to the target site in the user-defined alarm strategy; the alarm unit 46 is used to determine the site to be alarmed according to the user-defined alarm strategy An alarm is issued to the site to be alarmed.

[0078] Optionally, the alarm unit includes: a first determination module, configured to determine the standard operating parameters of the site to be alarmed according to the site to be alarmed; a generation module, used to set the value at the site to be alarmed If it is different from the s...

Abstract

This aspect provides a DCS flow processing method and device, the method comprising: obtaining the DCS flow of the DCS system from a mirror port of a switch connected to the DCS system; analyzing the DCS flow to obtain the DCS system a plurality of DCS sites; according to the target site in the user-defined alarm strategy, determine the site to be alarmed from the multiple DCS sites; according to the user-defined alarm strategy, the site to be alarmed alarm. It solves the technical problem that the detection object of the existing DCS system flow detection technical scheme is relatively single, resulting in poor detection effect.

Description

technical field [0001] The invention relates to industrial control network monitoring security, in particular to a DCS flow processing method and device. Background technique [0002] The DCS system is a decentralized control system. It adopts the basic design idea of ​​decentralized control, centralized operation and management, and adopts a structural form of multi-layer hierarchy and cooperation and autonomy. Its main feature is its centralized management and decentralized control. At present, DCS has been widely used in various industries such as electric power, metallurgy, petrochemical and so on. [0003] In order to ensure the normal operation of the industrial control network, it is necessary to detect abnormalities in the traffic of the above-mentioned DCS system. The traffic detection function of the existing DCS system only includes detection functions for new IP, new MAC, traffic size, and fixed risk codes. [0004] It should be noted that the detection object ...
