A method and system for data access between networks based on security isolation

Abstract

Embodiments of the present invention provide a method and system for inter-network data access based on security isolation. The method is applied to the first network and the second network with different security levels, including: generating virtual desktop information of the second network; The virtual desktop information is sent to the first network through the first channel, and displayed to the user in the form of a virtual desktop; the file transfer command input by the user through the virtual desktop is obtained, and the file transfer command is sent to the second network through the first channel network; the file transfer instruction includes an instruction to download a second network file; according to the instruction to download a second network file, the file downloaded by the second network according to the download instruction is sent to the first network through a second channel. The embodiment of the present invention provides a reliable channel for instruction and data transmission among multiple networks, realizes safe virtual desktop access and file resource exchange, and provides users with a convenient and safe information sharing method.

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...
