Semi-physical demonstration and verification platform and method for industrial control system information security protection

Abstract

The invention discloses a semi-object demonstration verifying platform and method for the information safety protection of an industrial control system. The platform comprises a physical layer, a control layer and a monitoring layer, wherein the physical layer, the control layer and the monitoring layer are connected sequentially. The physical layer is used for constructing and displaying a virtual physical object mode, simulating an operating physical object model under the control of a control instruction of the control layer, and generating real-time field data. The control layer is used for generating the control instruction according to the production real-time data uploaded by the physical layer and a unified dispatching instruction sent by the monitoring layer and an embedded information safety protection algorithm. The monitoring layer is used for generating the unified dispatching instruction according to the system real-time operation data and control instruction uploaded by the control layer, and achieving the real-time monitoring and control of an actual production process. The platform provided by the invention is used for achieving the research and verification of the information safety protection theory in different industrial control fields. The platform is transparent in attack propagation, is intelligent and visual in protection, and solves a problem that a conventional verifying platform is not high in expandability.

Description

technical field [0001] The invention relates to the technical field of industrial control system information security defense, and more specifically, to a semi-physical demonstration and verification platform and method for industrial control system information security protection. Background technique [0002] In recent years, with the rapid development of information and communication technology, modern industrial control systems have become an information system that deeply integrates computing processes, communication networks, and physical equipment; the security issues of industrial control systems have become increasingly prominent. [0003] The hierarchical structure of industrial control system includes enterprise layer, monitoring layer, control layer and physical layer. Due to the different division of labor at each layer and the differences in information security threats faced by each layer, a single protection technology is difficult to effectively deal with in...
