The industrial control systems of coal enterprises play an important role in modern production.However,with the rapid development of information technology and the improvement of networking,these systems are also facing increasingly serious network security threats.In order to ensure the security of the industrial control system of coal enterprises,this paper conducts network security risk assessment research in this field.By analyzing the characteristics of the industrial control system of coal enterprises and common network attack methods,a corresponding assessment model is established and a A comprehensive risk assessment approach.This method combines factors such as threats,potential vulnerabilities,and impact levels to comprehensively assess the network security risks of coal enterprises'industrial control systems and provide scientific basis for their security protection.
