Linux服务器登录安全配置

Linux操作系统在服务器租用领域应用非常广泛,与此同时安全性问题也不容小视,网络上每天都存在扫描、注入、攻击等,而作为Linux的第一道入口“登录”显得至关重要。如何配置安全的登陆防护,今天跟大家重点分享一下!

修改SSH端口

Linux系统默认使用22作为SSH端口,但是默认端口非常容易被扫描或者暴力破解,将其修改为一个不容易猜到的端口非常有必要。

root@ip-172-31-13-36:~# vi /etc/ssh/sshd_config



把22修改为其他端口即可!

禁用root直接登陆

root用户在Linux系统中处于天神级别,一旦被别人获取您服务器root权限,后果不堪设想。我们可以新建一个普通用户,然后将root用户禁止登录,大致的做法如下:

#新建一个用户mifan

useradd mifan

#为hixz设置密码

passwd mifan

#修改ssh配置文件

vi /etc/ssh/sshd_config

#将PermitRootLogin yes

改为PermitRootLogin no,

或者注释这一行

#重启ssh服务

service sshd restart



修改配置文件需要root用户才能执行,完成之后root用户将不能登录,使用普通用户(mifan)登录即可,若某些操作必须用到root权限,可以使用su -切换为root,或者加上sudo命令。

使用密钥文件登陆

1.使用命令ssh-keygen -t rsa生成密钥,会生成一个私钥和一个公钥,在提示输入passphrase时如果不输入,直接回车,那么以后你登录服务器就不会验证密码,否则会要求你输入passphrase,默认会将私钥放在/root/.ssh/id_rsa公钥放在/root/.ssh/id_rsa.pub

2.将公钥拷贝到远程服务器上的/root/.ssh/authorized_keys文件

,注意,文件名一定要叫authorized_keys

3.客户端上保留私钥,公钥留不留都可以。也就是服务器上要有公钥,客户端上要有私钥。这样就可以实现无密码验证登录了。

其他配置

不要随意执行来历不明的第三方脚本

不要擅自将服务器权限转交给他人

不要过度依赖于IDC商家的自动备份,自己定期备份数据也是非常重要的

及时检查修复服务器、程序漏洞

设置复杂的安全口令

其它,欢迎补充
