如何保证Linux服务器的安全

很少见有人马上为一台新安装的服务器做安全措施，然而我们生活所在的这个社会使得这件事情是必要的。不过为什么仍旧这么多人把它拖在最后？我也做过相同的事，这通常可以归结为我们想要马上去折腾那些有趣的东西。希望这篇文章将向大家展示，确保服务器安全没有你想得那样难。在攻击开始后，俯瞰你的“堡垒”，也相当享受。

这篇文章为 Ubuntu 12.04.2 LTS 而写，你也可以在任何其他 Linux 分发版上做相同的事情。

我从哪儿开始？

如果服务器已经有了一个公有IP，你会希望立即锁定 root 访问。事实上，你得锁定整个ssh访问，并确保只有你可以访问。增加一个新用户，把它加入admin组（在/etc/sudoers预配置以拥有sudo访问权限）。
