Network security protection system for civil air defense engineering

Abstract

The invention discloses a network security protection system for civil air defense engineering, which belongs to the field of industrial control network security. The network security protection system comprises embedded hardware, embedded basic software and a business scenario application. The embedded hardware comprises a data isolation switching module, an internal network controller M287 and an external network controller M287. The data isolation switching module comprises a control unit FPGA, a storage unit dual-port RAM, and a data channel. The internal network controller M287 and the external network controller M287 are two sets of independent and high-performance embedded hardware, and each has an arithmetic unit, a storage unit and a switching unit which are independent. The internal network controller M287 is responsible for accessing a field end control network. The external network controller M287 is responsible for accessing an information end network. The internal networkcontroller M287 and the external network controller M287 are connected to the data isolation switching module composed of the storage unit dual-port RAM and the control unit FPGA respectively by means of an 8-bit IO parallel busbar, and isolate the TCP / IP communication at the physical level. The network security protection system has the advantage of solving the problems of relatively single protection capability 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...
