Safety isolation control computer system

Abstract

The invention discloses a safety isolation control computer system. The system comprises an external network device used for being in communication connection with an external network, an internal network device used for being in communication connection with an internal network, a processor device used for being electrically connected to the external network device or the internal network deviceto form an external network computer or an internal network computer, and a switching device used for switching an electric connection between the external network device and the processor device andan electric connection between the internal network device and the processor device, wherein the switching device is electrically connected to the external network device, the internal network deviceand the processor device respectively. According to the safety isolation control computer system, the electric connection between the external network device and the processor device and the electricconnection between the internal network device and the processor device are switched through the switching device, the physical isolation of the internal network and the external network can be achieved, and the safe isolation of working modes of the internal network and the external network is achieved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a security isolation control computer system used in a dual-network office environment involving a secret-related network and a non-secret-related network. Background technique [0002] With the widespread application of computers and the urgent need for dual-network office work in e-government, the dual-network isolation computer solution represented by switches and isolation cards has been applied to a certain extent. However, due to the defects of the architecture itself, the existing securely isolated computer products have serious security and leakage risks. If they continue to be used in important organizations such as the party, government, and military, they will inevitably pose a major threat to my country's information security. Currently, network interface isolation or physical isolation is usually used to isolate internal and external network computers. However, f...

AI Technical Summary

Problems solved by technology

However, for the network interface isolation method, the network cables of the internal and external network computers may be misplugged, resulting in isolation failure

However, the physical isolation method not only increases the physical space and cost, but also is inconvenient to use.
