Mainstream protocol implementation and monitoring analysis platform for industrial control system

Abstract

The invention discloses a mainstream protocol implementation and monitoring analysis platform for an industrial control system. The platform comprises a simulation module for simulating a virtual controlled object, a controller PLC upper computer and a programmable logic controller (PLC) and a PLC industrial control protocol deep packet analysis and monitoring module, wherein the simulation moduleis used for simulating a mathematical abstract industrial control system; the PLC is used for receiving and storing a simulation system variable signal sent by the simulation module into a specific register and sending the signal to the upper computer, and meanwhile, receiving a control signal sent by the upper computer and sending the control signal to the controlled object of the simulation module; the PLC industrial control protocol deep packet analysis and monitoring module is used for acquiring protocol data flow of the industrial control system generated by communication between the upper computer and the PLC in real time, and carrying out real-time full analysis and monitoring on the acquired protocol data flow, the storage and the on-line display of an analysis result are realized, and meanwhile, the intrusion detection of the industrial control system is realized.

Description

technical field [0001] The invention relates to the security field of industrial control systems, in particular to the intrusion detection and protocol monitoring of the industrial control system for its unique protocol, and the construction of an experimental platform. Background technique [0002] In recent years, security incidents in the field of industrial control have occurred frequently, such as the Stuxnet incident in 2010 and the "BlackEnergy" power grid incident in Ukraine in 2015. Industrial control systems are often used in important national infrastructure and key industrial facilities such as chemical engineering, water conservancy, power grids, communications, government facilities, water treatment, and nuclear reaction facilities. As early as 2006, the United States regarded industrial control system security as an important field of scientific research, and the issue of industrial control security has received more and more attention. The communication betw...

Problems solved by technology

[0012] At present, research on the construction of security platforms for industrial control systems is still in its infancy. Most people know little about the protocol formats and characteristics in the field of industrial control. Mainstream protocol implementation and full analysis platform help to understand the structure, operation process and status, protocol format and characteristics of the industrial control system itself, and have a more intuitive understanding and clear understanding of typical industrial control processes
