Internetwork data access method and system based on safety isolation

Abstract

The embodiment of the invention provides an internetwork data access method and system based on safety isolation. The method is applied to a first network and a second network with different safety levels, and comprises the following steps: generating virtual desktop information of the second network; sending the virtual desktop information to the first network through a first channel, and displaying the virtual desktop information to a user in a virtual desktop way; acquiring a file transmission instruction input by the user through the virtual desktop, and sending the file transmission instruction to the second network through the first channel, wherein the file transmission instruction comprises an instruction for downloading the second network file; and sending a file downloaded by thesecond network according to a downloading instruction to the first network according to the instruction for downloading the second network file. Through the method provided by the embodiment of the invention, a reliable channel for instruction and data transmission is constructed among multiple networks, the safe virtual desktop access and file resource exchange is realized, and a convenient andfast information sharing way is provided for the user.

Description

technical field [0001] The invention belongs to the fields of information security and network data exchange, and in particular relates to a method and system for inter-network data access based on security isolation. Background technique [0002] Party, government and military organizations at all levels in the country are often faced with the situation of using two or even multiple sets of networks. For example, the government affairs system of the party and government departments has a dedicated government network, a government network, command network, etc., and according to security and confidentiality requirements, these networks usually need to be physically or logically isolated, causing users to frequently switch to use multiple sets of networks, which is not conducive to information sharing and network management, seriously affects work efficiency, and is likely to cause security problems. Hidden dangers and unnecessary waste of resources. Therefore, from the pers...
