Research on security protection system of industrial control system

Abstract

Industrial control system(ICS) is widely used in water treatment, power, oil, transportation, military industry and other industries. The safety and stability are related to the normal operation of key national infrastructures. ICS are facing with serious security threats with the advancement of digital production and intelligent manufacturing. This paper proposes and designs a set of in-depth ICS security protection system by discussing the typical attack methods and the weaknesses of existing protection measures，and elaborates its technical focus from five aspects: physical security, data security, network security, host and application security, and control security. And then a comprehensive security protection platform is built on the basis of a trusted platform, forming a set of adaptive, closed-loop, security models and mechanisms that can self-defense and recover, maintain the safety of the ICS in three dimensions.It is helpful for security and stability operation of ICS.
