为啥我感觉不应该用root登录？

chriswongxp · 2018-12-07 14:24:45

我以前用gnome-ubuntu的时候，好像用root登录是做了限制的，而且登录图形界面不是应该以用户的身份吧？就算root在终端还是轻易不要用的，可以给自己的角色加上sudoer权限

ext3 · 2018-12-07 17:01:53

我现在出现的问题是没更新之前是可以用root登录的，更新后不能了，root默认是被限制登录的，但可以通过修改pam解除限制

AMOR · 2019-01-09 10:53:58

其实我想问为什么不建议root直接登录DM啊

驿窗 · 2019-01-09 10:59:34

安全最大化，风险最小化；

具体哪里有问题我不专业，也说不清楚，但理论上，可以不用root权限的时候，坚决不要用root，这是原则；

root权限太大了～

因为你并不知道你在干嘛。如果你清楚地知道你有一个root会话里面那么多root进程会导致什么样显式的潜在的后果，那可以，没问题。但实际上你不知道，就算是专业系统管理员也不能知道哪些进程可能会成为攻击的入口，毕竟你没有精确的控制操作系统的每个字节。
