An industrial control network attack and defense experiment platform and a semi-physical simulation method

Abstract

The invention relates to an industrial control network attack and defense experiment platform and a semi-physical simulation method. The platform comprises a local experiment platform and a remote experiment platform. A simulation host, a PLC and an industrial touch screen of the local experiment platform are respectively connected with the industrial Ethernet switch to form a local area network;the remote experiment platform simulation host is connected to the local area network through the Internet; an experiment system with a network attack simulation module and a network damage simulationmodule is built on each simulation host and a PLC, and the experiment system is operated to adjust parameters of each experiment system controller until an expected control effect is achieved. Not only can a network damage technology be utilized to simulate a remote network environment in a local network to carry out an experiment, but also remote network equipment can be deployed at different places to carry out a remote experiment. A remote network attack and a local network attack can be initiated, and the authenticity of the network attack is improved. In the aspects of authenticity, reusability and cost, most of network attack, defense and control experiment requirements can be met.

Description

technical field [0001] The invention relates to the field of industrial control system network security, in particular to an industrial control network attack and defense experiment platform and a semi-physical simulation method. Background technique [0002] Industrial control network refers to the use of controllers, sensors, and actuators with communication capabilities as network nodes, fieldbus or industrial Ethernet as communication media, and the completion of measurement and control in an open, digital, and multi-node form. industrial network of tasks. In the process of deep integration of informatization and industrialization, while the industrial control network has greatly improved the flexibility of the control system and the efficiency of industrial production, it has also extended the problem of network information security to the field of industrial production, and has caused increasingly severe equipment security and Production safety issues, these issues ha...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, although the full simulation experiment platform can simulate complex network characteristics, and is low in cost and easy to use, it lacks the authenticity of network attacks and controlled objects to a certain extent.

However, although the experimental environment of the all-physical experimental platform is real, it is expensive, has a long construction period, and has low reusability.

In addition, because the existing hardware-in-the-loop simulation experiment platform uses control system simulation software instead of network simulation software, and does not introduce actual industrial networks, it can only simulate simple network environments and some types of network attacks, which has certain limitations.

Therefore, it is necessary to overcome the defects of authenticity, reusability and cost of the current hardware-in-the-loop experiment platform and corresponding experimental methods, and seek a hardware-in-the-loop simulation experiment platform and method that can optimize both authenticity and reliability.
