Research on the security protection strategy of industrial control network in key industries based on classified security protection standard 2.0

Abstract： In the context of the integration of industrialization and information in industrial construction, the interconnection and interoperability of the industrial control system has gradually strengthened, and the network security risks faced by the system have also become greater. Aiming at the current status of industrial control network security, this paper proposes an industrial control network security protection strategy that can realize the functions of isolation, monitoring, early warning, and auditing based on classified security protection standard 2.0. Taking the tobacco industry as an example, the application deployment and security verification have been completed, which provides a practical reference for the construction of industrial control system network security.
