Securing ssh
Open the config file: /etc/ssh/sshd_config and change the default ssh port.
Find the following string:
#Port 22
Edit the port (choose any port from range 1025-65535), for example 20120
Port 20120
Make sure you have the port opened in firewall Restart ssh (CentOS):
service sshd restart
Disable root login. Before disabling root login, create your own user, otherwise you will simply lose access to the server.
