Embodiment Construction

[0043] As mentioned earlier, the complexity and variability of OT systems increase the difficulty of security monitoring for OT systems. In the embodiment of the present invention, by improving the visibility of an OT system, the monitoring result of the OT system is improved, so as to effectively prevent security risks. Wherein, an OT monitoring system captures the data packets transmitted in the OT system, extracts information of at least one asset included in the OT system from the captured data packets, and then determines the OT System asset catalog. The asset catalog of the OT system can improve the visibility of the OT system and make the location of security risks more accurate.

[0044] Among them, the network information of the asset can be obtained from the transport layer header of the captured data packet. The captured data groups are classified according to the industrial protocol, and the description information of the asset is obtained from the data load of t...

Abstract

The invention relates to the technical field of industrial safety, in particular to a monitoring method, device and system for an operation technology OT system and a storage medium so as to improve the visibility of one OT system and effectively prevent safety risks. The OT monitoring system provided by the embodiment of the invention comprises at least one network sensor, which is configured toobtain at least one data packet transmitted in an OT system and send the data packet to an OT monitoring device; an OT monitoring device, which is configured to extract information of at least one asset included in an OT system from at least one acquired data packet, and providing a first application programming interface API according to the extracted information of the at least one asset, generating an asset directory of the OT system when the first API is called, or determining the asset directory of the OT system according to the extracted information of the at least one asset. And the asset directory of the OT system can improve the visibility of the OT system, so that the security risk positioning is more accurate.

Description

technical field [0001] The present invention relates to the technical field of industrial safety, in particular to a monitoring method, device, system and storage medium of an Operational Technology (Operational Technology, OT) system. Background technique [0002] The OT system, which may also be called an industrial control system (Industrial Control System, ICS), is used to realize automatic control of industrial processes. An OT system can be a wind power generation system, an automobile manufacturing workshop, a pharmaceutical factory, a city's sewage treatment system, etc. [0003] The traditional OT system adopts a closed design, and it is difficult for network attacks to threaten it. However, with the development of automated manufacturing and process control technology, the OT system has widely adopted information technology (IT) technology, which is no longer a closed system, but the current OT system still lacks a complete safety monitoring mechanism to detect OT...
