Go2Linux posted a quick security tip about changing the SSH port

There a lot of ways to protect access to Linux Operating System driven servers trough ssh ports, this is just another one.
This is somehow, like covering your house's front door with bricks and enabling another door, where only you and your family knows. That way the first thing a burglar needs to do, is to find the door, only after that he will be able to try to open it.
ssh listen to port 22 by default, but you can change that behaviour, and the bots will not be able to attack your Linux server as they usually only attack to port 22.
