Depends on how paranoid you are. Every open port creates some risk. Generally
speaking ssh is fairly secure but there have been exploits found in it in the
past. As long as you keep things up2date you should be OK. You can as others
will suggest move the port ssh runs on to a non-standard port which means that
the scripts that run everyday looking for weak passwds and known exploits will
not know where to look. You can also disable root logins via ssh among other
things, depending on your level of paranoia.
