Current Situation Analysis and Countermeasures for Industrial Control Security at LNG Receiving Terminal
LNG,short for Liquefied Natural Gas,is a clean energy source whose share in China's energy supply is increasing year by year,gradually replacing traditional energy sources such as coal and oil in certain sectors.To ensure the supply of LNG energy,a large number of LNG receiving terminals have emerged.The industrial Distributed Control System(DCS)serves as the nerve center of an LNG receiving terminal,with the station control system being a crucial component.It integrates multiple functions such as data monitoring,data acquisition,and distributed control,capable of meeting the complex process requirements of LNG receiving terminals.With the continuous integration of information technology and industrialization,network security issues in industrial control systems have also arisen.Effectively safeguarding the information security of industrial control systems that have been in continuous operation for many years,in the face of escalating industrial information security threats,poses a significant challenge for LNG receiving terminals.This article focuses on Longkou LNG and briefly describes common industrial control security threats and security strategies for LNG receiving terminals.
