Example Embodiment

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings:

[0035] The main function of the physical partition is to strictly manage the data transmitted from the external network to the internal network and the data transmitted from the internal network to the external network on the basis of ensuring the safety of the internal network. The main purpose is to prevent insecure factors from the external network (including hackers, Trojan horses, viruses) from destroying important information and data on the internal network. Such as figure 1 Shown: The external network is used to provide various application services (HTTP, FTP, etc.) to the WAN. Users are required to provide data to the external network data server through various services. All or most of these data need to be transferred to the internal network for reprocessing. After processing, the data processing results will be fed back to the external network for pu...

Abstract

The invention provides a method for realizing physical partition of internal and external networks, and belongs to the field of network security. The method comprises the steps that the external network is provided with first physical partition equipment; the internal network is provided with second physical partition equipment; communication between the internal network and the external network is realized through the first physical partition equipment and the second physical partition equipment; at least one universal serial bus is arranged between the first physical partition equipment and the second physical partition equipment; and the communication between the first physical partition equipment and the second physical partition equipment is realized through the universal serial bus. The method realizes real-time data transmission between the internal network and the external network based on ensuring the security, and improves the real-time data responsiveness of the internal network and the external network greatly.

Description

technical field [0001] The invention belongs to the field of network security, and in particular relates to a method for realizing physical separation of internal and external networks. Background technique [0002] Nowadays, more and more attention has been paid to the security of internal and external networks. As a kind of network security equipment, "physical isolation" has been widely used in today's internal and external network isolation. [0003] At present, most of the physical isolation between internal and external networks is realized by means of hardware switches or "data ferry". The advantage of this type of physical partition is that it completely isolates the logical link of data transmission between the internal and external networks, and has high security. However, the disadvantage of this method is that real-time communication between internal and external networks cannot be realized. Contents of the invention [0004] The purpose of the present invent...
