A network security protection system for civil air defense engineering

Abstract

The invention relates to a network safety protection system for civil air defense engineering, which belongs to the field of industrial control network safety. Including embedded hardware, embedded basic software and business scenario application software. Embedded hardware includes data isolation and exchange module, internal network controller M287, and external network controller M287; data isolation and exchange module includes control unit FPGA, storage unit dual-port RAM, and data channel. The internal network controller M287 and the external network controller M287 are two independent high-performance embedded hardware, both of which have independent computing units, storage units and switching units. The internal network controller M287 is responsible for connecting to the field end control network; The network controller M287 is responsible for accessing the information terminal network; the internal network controller M287 and the external network controller M287 are respectively connected to the data isolation exchange module composed of the storage unit dual-port RAM and the control unit FPGA through an 8-bit IO parallel bus. The physical level isolates TCP / IP communication. The advantage is that it solves the problems of single protection ability and the like.

Description

technical field [0001] The invention belongs to the field of industrial control network security, and in particular provides a network security protection system for civil air defense projects. There are many automation and information systems in civil air defense projects, and they belong to semi-military projects, which have high requirements for security protection. The system has the characteristics of physical isolation, secure communication and data security detection. Background technique [0002] As the Internet of Things, cloud computing, and mobile application technologies are more and more widely used in civil air defense engineering, its information security issues are receiving more and more attention. Information security issues including data, physics, and networks must be maintained in civil air defense engineering. In order to ensure the stable operation of the overall internal information system and ensure that the control process is not affected in peaceti...
