If you do open port 22 to the world make sure you have decent passwords, ie lots of letters, numbers upper and lower case and quite a few characters the more the better really. If you are going to connect in remotley then if it is just from a known location you can firewall to just allow that location to get in or if you only connect remotley from your machines eg a laptop etc you can pre exchange the RSA sigs and not rely on passwords at all.
