Data security exchange method based on black list and white list

Abstract

The invention discloses a data security exchange method based on a black list and a white list, comprising the steps of reading data to be exchanged and matching the data with rules and strategies; conducting protocol stripping to successfully matched data to acquire pure data contents; matching the pure data contents with keywords in the white list; transmitting the data to be exchanged to the separated card of a first network upon successful matching of the data, writing the pure data contents into a single-way data transmission channel by the separated card of the first network; upon unsuccessful matching of the data, matching the pure data contents with keywords in the black list and pushing the pure data contents into users for selection configuration. In the data security exchange method, a problem that a traditional isolating device cannot meet special transmission requirements is solved by an intelligent white list technology, keywords in the data are extracted by main programs, the white list and the operator are automatically expanded, and the back list and the white list are manually added, so that data interaction security is ensured and data transmission flexibility is enhanced.

Description

technical field [0001] The invention relates to a data security exchange method, in particular to a data security exchange method based on black and white lists. Background technique [0002] With the maturity of network technology and continuous improvement of applications, the Internet is increasingly integrated into all aspects of society. On the one hand, a series of network applications such as enterprise Internet access, e-commerce, distance education, and telemedicine are booming, and people's daily life is increasingly closely related to the network; on the other hand, the composition of network users is becoming more and more diverse. Targeted network intrusions and attacks are becoming more and more frequent. While enjoying the rich and convenient information brought by the Internet, people are also increasingly troubled by frequent network attacks, virus floods, unauthorized access, information leaks and other problems. [0003] In many important fields such as ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the existing power system isolation technology is not flexible enough in the real operating environment, and the function of judging the information interaction behavior of the internal and external network is single. In some special environments, some information that the user wants to transmit is due to some reasons ( For example, if the keyword review fails), it is blocked by the isolation device and cannot be transmitted, but the user confirms that there is no problem with this information, so it can only be transmitted by offline copying, which is very inconvenient
