浅谈网闸——安全隔离与信息交换系统

Gateway-Security Isolation＆Information Exchange System

防火墙已成为网络边界安全重要保障，在发展过程中，人们最终意识到其在安全方面的局限性。高安全性、易用性之间的矛盾没有很好地得到解决。防火墙单系统架构在安全性方面的缺陷，使网络应用迫切追求一种更高安全性的解决方案，期盼更安全的技术。在市场不断追求高安全性技术的过程中，目前安全市场上出现了一匹“黑马”——安全隔离与信息交换系统，在业界简称为网闸。经过长期的市场考验和技术演变创新后，网闸最终赢得了认可，具有最高安全性的特征，已悄然成为高安全性要求的首选解决方案，其主要的实现思路为在安全隔离的前提下，提供可高度可控的数据交换。它既能实现网络间的安全隔离。又能实现数据的实时交换。

The firewall has become an important border security, network security in the development process,people finally realized their limitations in terms of security.High security, ease of use,the conflict between the not well resolved.Single system architecture firewall security deficiencies,so that the urgent pursuit of a higher network application security solutions,look forward to safer technologies.In the market continuing to pursue high-security technology,process,the current security market appeared＂dark horse＂-safety isolated and information-exchange system,referred to as the gateway in the industry.After a long market test of the evolution of innovation and technology, the gateway was endorsed won,the security of the features, quietly become a high security requirements of the preferred solution, the main method was also isolated in the premise of safety,provide a high degree of control data exchange,it not only the safety of isolation between networks,but also real-time exchange of data.
