Summary of research on endogenous information security technology of industrial measurement and control equipment

Abstract : Industrial measurement and control equipment is the nerve center of industrial control system , Its information security is directly related to the safety of industrial control system . Traditional information security protection technology has limitations , The network cannot block the access of physical media transmission data and physical devices , Even physically isolated industrial measurement and control equipment , It can also be an attack target , There is an urgent need to enhance the endogenous safety protection ability of industrial measurement and control equipment . This paper combines relevant international standards and national standards , The endogenous information security protection technology of industrial measurement and control equipment is divided into static reinforcement technology and dynamic protection technology , The seven types of information security protection technologies involved are logically classified , The term definition of endogenous information security of industrial measurement and control equipment is given , And specific analysis 、 The advantages and disadvantages of the existing relevant theoretical research and key technologies are evaluated . Last , The development trend of endogenous information security protection technology of industrial measurement and control equipment is prospected .
