Network Security in the Industrial Control System: A Survey
Yang Li, Shihao Wu, Quan Pan

TL;DR
This survey reviews the security protocols and defense strategies in industrial control systems, highlighting recent developments and challenges in protecting ICS networks amid increasing connectivity.
Contribution
It provides a comprehensive overview of ICS protocols and security measures, offering new insights into defense strategies for industrial network security.
Findings
Protocols in ICS are highly vulnerable due to diversity.
Defense in Depth strategies are crucial for ICS security.
Recent developments focus on encryption, intrusion detection, and SDN.
Abstract
Along with the development of intelligent manufacturing, especially with the high connectivity of the industrial control system (ICS), the network security of ICS becomes more important. And in recent years, there has been much research on the security of the ICS network. However, in practical usage, there are many types of protocols, which means a high vulnerability in protocols. Therefore, in this paper, we give a complete review of the protocols that are usually used in ICS. Then, we give a comprehensive review on network security in terms of Defence in Depth (DiD), including data encryption, access control policy, intrusion detection system, software-defined network, etc. Through these works, we try to provide a new perspective on the exciting new developments in this field.
