Abstract: Detection is the first step of security, and the effective detection and acquisition of the assets information of industrial control equipment is an important starting point for the realization of industrial Internet information monitoring and security vulnerability discovery. This paper combines the communication mechanism and data message structure of four industrial control protocols, modbus, s7, dnp3 and BACnet, to propose a general method for concurrent asset detection for industrial control equipment running on different industrial control protocols. The experimental result proves that the method is more versatile than the traditional detection method, and improves the asset information detection rate and accuracy of the industrial control equipment in performance, which can help the safety warning and equipment detection and maintenance of the industrial control equipment.
