Network isolation system

Abstract

The invention discloses a network isolation system. The network isolation system comprises a data processing system used for transmitting data between an internal network and an external network, wherein the internal network is provided with a memory and transmission certificate; the external network is provided with access certificate; the data processing system consists of a data monitoring unit a and a data monitoring unit b; the transmission certificate performs one-way data transmission with the data monitoring unit b and the external network in sequence; the access certificate performs one-way data transmission with the data monitoring unit a and the internal network in sequence; the information of an internal network user is certificated by utilizing the transmission certificate; the information of an external network user is certificated by utilizing the access certificate; the memory of the internal network automatically records the information such as transmission data and user; a series of safe processing is performed by utilizing the data monitoring unit a and the data monitoring unit b; the potential safety hazard such as hacker attack, infiltration of malice code and virus and information leakage can be prevented effectively; and the safe isolation and the safe information exchange of the internal network and the external network are realized.

Description

technical field [0001] The invention relates to a network isolation system. Background technique [0002] At present, most of the domestic government agencies and the military's classified networks are undergoing physical isolation, in addition to a large number of important departments, such as finance, electricity, telecommunications, medical, transportation and other industry networks are more and more physical isolation. demand. However, the absolute isolation between internal and external networks makes it impossible to exchange information between networks, forming many isolated "information islands", which brings a lot of inconvenience to the development of "e-government" and the application of industry informatization. How to achieve secure isolation between the trusted network (intranet) and the untrusted network (external network) and achieve reliable exchange of information has become an urgent problem to be solved. SUMMARY OF THE INVENTION [0003] The techni...
