Embodiment Construction

[0018] The present invention provides an efficient, safe and manageable file transmission method between networks. By using the method, the interaction efficiency of electronic files between physically isolated networks can be improved while maintaining the characteristics of physical isolation of networks.

[0019] The present invention adopts the following manner to solve the problem of file interaction between networks. The present invention includes three parts, namely, the internal network server, the external server, and the ferry hardware. Among them, connect two or more storage modules to the ferry hardware, and then use USB cables to connect to the intranet server and the extranet server. Among them, on the ferry hardware device, data control is performed to ensure that one storage can only be occupied by one server. In this way, at any time, the internal and external networks are isolated from each other.

[0020] Both the intranet server and the extranet server pr...

Abstract

The invention discloses a device and a method for internetwork file ferry. The device comprises two networks which are isolated mutually, wherein each of two networks is provided with a server, the servers are connected to a universal serial bus (USB) switcher through USB lines respectively, the USB switcher guarantees that only one server is connected to a memory on the USB switcher each time, and a file is transmitted to one server from the other server through the memory of the USB switcher. By the aid of the method and the device, the internetwork file ferry can be conducted efficiently, the internetwork information exchange is convenient and the internal and external network exchange information safety is guaranteed.

Description

technical field [0001] The invention is suitable for the fields of information security and network data exchange. Background technique [0002] At present, for some places with high requirements for computer network security, such as military industrial units, scientific research institutions, R&D institutions of enterprises, etc., in order to ensure the security of internal information, a dedicated internal network will be established. isolated from the network. In this way, the security of the internal network has been greatly improved, but it has brought great changes to the information exchange between the internal and external networks. Communication and information disclosure are also essential. Therefore, most companies currently use the method of burning CD-ROMs and using secure USB flash drives to exchange information. The above solutions also inevitably have problems such as long interaction cycle, low efficiency, and complex log auditing. SUMMARY OF THE INVEN...
