Research on Edge Side Security Enhancement Technology for Industrial Control Scenarios

With the rapid development of industrial Internet, the computing architecture and mode of cloud side collaboration are more and more widely used in industrial control systems. While greatly promoting the upgrading of industrial control system capabilities, it also makes the interface of industrial control systems increasingly open, which inevitably brings the problem of edge side information security. This paper studies the key technology of edge side security enhancement for industrial control scenarios, and carries out the design and implementation of security enhancement on the lightweight edge computing platform based on ReWorks embedded real-time operating system. This includes supporting user hierarchical management, virtual encrypted partition storage, source and destination port mapping, system audit tracing and other related functional components, providing functional support for the security protection of edge side platforms.
