Network security computer system and implementation method thereof

Abstract

The invention relates to a network security computer system and an implementation method thereof. The method comprises the following steps: S1, constructing a network security computer system; S2, setting the network security computer system to respectively work with an external network computer or an internal network computer through a switching device, when the network security computer system works with the internal network computer, executing step S3, and otherwise, executing step S4; S3, the intranet computer constructs the working environment of the intranet computer through a TF card and a VGA interface, and supports the functions of a safety monitor and an intelligent monitor; and S4, closing the intranet computer, constructing a working environment of the extranet computer by theextranet computer through an EMMC system, and entering a general computer state. By implementing the network security computer system and the network security computer method, the confidentiality andthe integrity of a high-grade network system can be ensured, and complete physical isolation between an internal network and an external network is realized while coexistence of computers in the internal network and the external network is ensured.

Description

technical field [0001] The present invention relates to the field of network security, and more specifically relates to a network security computer system and its implementation method. Background technique [0002] With the widespread use of computers and the urgent need for dual-network office, 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, for the network interface isolation method, the network cables of the internal and external network ...

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, the cross-use of mobile media between confidential and non-confidential computers, and the sharing of storage components such as CPU cache, motherboard video memory, and flash memory may cause isolation. fail

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