第 4 章 After installation

Once the system is installed you can still do more to secure the system; some of the steps described in this chapter can be taken. Of course this really depends on your setup but for physical access prevention you should read 第 4.3 节 “修改 BIOS (再次)”,第 4.4 节 “设置 LILO 或 GRUB 密码”, 第 4.6 节 “取消 root 的提示等待”, 第 4.7 节 “限制控制台登录”, and 第 4.8 节 “限制系统通过控制台重起”.

在连入任何网络前, 特别是将要连入公网之前, 至少应该执行一次安全更新(参阅 第 4.2 节 “进行安全更新”). 最好, 您能对系统进行系统快照(参阅 第 4.19 节 “生成系统快照”).
