Abstract
With the rapid development of informatization and automation technology,industrial control sys-tems(ICS)in the petroleum and petrochemical industries are facing increasingly complex network security threats.Especially in the context of the accelerated networking and intelligent process,the vulnerability and at-tack surface of industrial control systems are expanding day by day,and various risks such as network attacks,malware,and insider threats seriously threaten the production security and data security of the petroleum and petrochemical industry.The research status of industrial control system network security in the petroleum and petrochemical industry at home and abroad was firstly analyzed,and then the main security threats faced by the industry were systematically combed,and the existing protection strategies were evaluated.Based on the concept of defense in depth,a series of security protection strategies,such as network isolation,identity authentication,behavior monitoring,data encryption and backup,were proposed to enhance the anti-attack capability of indus-trial control system in petroleum and petrochemical industry.Finally,through the analysis of typical network at-tack cases,the concrete measures and suggestions for strengthening network security protection in petroleum and petrochemical industry were put forward.This paper provided theoretical basis and practical guidance for impro-ving the safety of industrial control system in petroleum and petrochemical industry.关键词
