Integrated Protection Technology of Internal Security in Industrial Control Network

With the continuous development of new industrialization, industrial control networks, as the basic core of industrial production and operation, drive the operation of many fields from energy production to manufacturing. While enabling industrial production, industrial control networks are facing unprecedented security challenges. At present, the traditional network security protection method of industrial control system can no longer meet the comprehensive requirements of internal security of industrial control network. This paper aims to discuss the situation of industrial control security at home and abroad, discuss the pain points and key protection technologies of industrial control security, explore new security protection systems, methods and future development routes, in order to provide reference for improving the security protection capability of industrial control system.
