It’s always a good idea to change the standard SSH (Secure Shell) port unless you plan on disabling SSH all together. This will prevent hackers from brute forcing into your system. Instead of 22, use something like 93702. Really any 5 randoms numbers will work.
How-To
Under “Control Panel” select “Terminal & SNMP”. You’ll see a checkbox to enable/disable SSH. Check the SSH box and then simply change the port number in the input field.
For best security, when you’re done using SSH go back to these settings and disable SSH all together.
