基于SNT的网络隔离

Network Seperation Based on the SNT

内、外网隔离是目前一种常见的网络建设方案,这种方案在提高安全性的同时也给用户带来了许多不便,而且机器在内外网之间的切换也存在着安全隐患。文章根据安全网络终端(SNT)的特点,提出了一种基于SNT的网络隔离方案,既允许用户在两个网络之间自由地切换,又能够保证网络的物理隔离。

Presently, the separation between intranet and extranet is a common precept of network construction, which can improve the security but brings lots of inconvenience to the users and some security bugs when the PC is switching from one to another. According to the characteristics of Security Network Terminal （SNT）, this text puts forward a precept based on the SNT, which not only allows users switching freely but also guarantees the physical separation of network.
