A method and device to safely exchange computer data

Abstract

The provided safe data exchange method comprises: setting a safe data exchange device between the inner computer system and external network system; keeping the device to connect with one of inner computer and external system. This invention ensures data transmission and exchange.

Description

technical field [0001] The invention relates to a network security product, specifically a method and device for exchanging computer data applied between a computer system and network information exchange to ensure safe and accurate exchange of information. Background technique [0002] The application of the network has brought great convenience to our current life and work, such as timely information transmission and electronic payment. However, due to many security risks in the Internet, my country's national security department requires that the government office network must be physically separated from the Internet. Although this guarantees However, how to ensure safe, rapid and accurate data exchange between the two networks has become an urgent problem to be solved.

[0002] The application of the network has brought great convenience to our current life and work, such as timely information transmission and electronic payment. However, due to many security risks in the Internet, my country's national security department requires that the government office network must be physically separated from the Internet. Although this guarantees However, how to ensure safe, rapid and accurate data exchange between the two networks has become an urgent problem to be solved.

At present, the common method used by general units is to manually use floppy disks as a tool for exchanging files between internal and external networks. The biggest limitation of this method is that once the file is too large and exceeds the storage space of the floppy disk, there is no way to use the floppy disk to exchange data.

[0003] For this reason, as an improvement to exchanging data with floppy disks, some users consider replacing floppy disks with larger-capacity USB disks. Although this solves the problem of data storage capacity to a certain extent, manual data exchange methods are very inconvenient to operate. , the file needs to be transferred multiple times, and it needs to be transferred to the designated device, and because the file exchange is carried out in a decentralized manner, it cannot be managed centrally, and it is difficult to determine the responsibility for the problem; the professional or technical level of the operators is uneven , it will result in lenient censorship of the exchanged data content, and it is difficult to control misoperation; and the most important thing is that it cannot automatically complete the file exchange work on a regular basis. In terms of e-government and web page updates that require frequent data exchange , obviously not a good, mature solution

[0004] Recently, some companies have successively launched a complete set of solutions to solve file exchange or access between isolated networks, such as using isolation firewalls and intrusion detection and other auxiliary means to exchange data between internal and external networks, but due to the existence of their own exchange platforms At the same time, due to its design flaws, some specially designed Trojan horse programs may also steal sensitive information through this type of system
