The following steps will make your Linux server more secure:

1, Edit sshd_config to disable root login.

vi /etc/ssh/sshd_config

make sure you have this line:

PermitRootLogin no

2, Change sshd port number to something other than 22, e.g.,

Port 1234

3, Make sure somebody can do su or sudo:

vi /etc/sudoers

add my name to sudo list:

bobsmith ALL=(ALL) ALL

4, Restart sshd

service sshd restart
