Securing ssh access is extremely vital for any server. There are a few things that you can do to secure it. This article will cover one the basics.

  1. The first this that I recommend doing is changing the ssh port. This will prevent a lot of login attempts from automatic scripts trying port 22. To do this edit the file /etc/ssh/sshd_config

    2. pico /etc/ssh/sshd_config

    Locate the line #Port 22, uncomment it and change the port to something random.
    Note: Please remember to open this port in your firewall if you use one. Failure to do so may lock you out if your own server !

  2. Allow only SSH 2 protocol

    3. Again edit /etc/ssh/sshd_config, locate the line #Protocol 2,1 and change it to Protocol 2

    After doing step 1 and 2 you have to restart sshd for the changes to take effect.

    service sshd restart
