Design And Implementation Of Industrial Control System Network Security System Of Aerospace Factory 211

With the development of information technology,industrial control system plays more and more important role in the enterprises.Industrial control system can not only greatly improve the industrial control equipments' work efficiency,but also facilitate the unified management of the enterprises to industrial control equipments.In recent years,the demand for the application of industrial control system is becoming more and more extensive, especially in the national military manufacturing enterprises.However,because of the lack of unified security planning,network security issue has become a key problem affecting the application of industrial control system. How to combine the classification protection system and implement the safe and e ffective industrial control system,has become the focus of the research on the construction of information system in military enterprise.This study is based on the above research background, taking the aerospace industry control system as the specific research object,and carries out the research and design on network security.This study firstly elaborates the network structure of industrial control system,and then makes risk analysis combining the current situation of the system,analyzes the safety require ments from two aspects of technical protection and management of the protection.Finally,take the aerospace 211 factory as an example,design the network plan of industrial control system in order to realize the network security isolation between industrial control system and classified information system,meet the demand for the use of industrial control,and design the network security system in detail from aspects of network protection,equipment protection and so on.In the process of research and design on the industrial control system's network security,this study combining theory with practice, effectively solves the network security problem of industrial control system in aerospace factory 211.The proposed design scheme for the network security problem in aerospace enterprises' industrial control system, has a certain reference value and promoting significance.
