Research on Data Integrity Protection Technology of Industrial Control Network

The industrial control network was used in a closed network at the beginning of its design. But in recent years, with the rapid development of the Internet of Things technology, the industrial control network needs to be interconnected with other information systems, exposing the vulnerability to the new network environment. This article introduces the security status of industrial control network and the security threats it faces, briefly describes the differences between industrial control network and IT network, and discusses the key technologies that play a role in the protection of industrial control network data integrity.
