用SSH实现网络的安全访问

传统的网络服务程序,如Telnet、FTP等服务在网络上都是通过明文传送数据、用户帐号和密码,使用窃听等网络攻击手段可以非常容易地截获这些数据、用户帐号和密码。而SSH有很多功能,它传送的是经过压缩的加密信息,目的是要在非安全网络上提供安全的远程登录和其他安全网络服务,使用它既可以代替Telnet,又可以为FTP、邮件传输、甚至为PPP提供一个安全的“通道”。在当今网络安全日益重要的情况下,保证网络访问的安全性很有必要。本文将介绍这种技术。

Use SSH to Realize the Network Safe Visit

Tradition network service,like Telnet,FTP in the network all is through the not encryption data transmission data,the user account and the password.network attack methods like interception may intercept these data,the user account and the password extremely easily.But SSH has Many functions,it transmits is the compression encryption information,the goal is must provide safe service in the not safe network,uses it both to be possible to replace Telnet,and may be FTP,the mail transmission,even is PPP provides safely "the channel".In the network security day by day important situation,guaranteed the security that the network visits is necessary very much.this article will introduce this kind of technology.
