If this were a PC I would never do this, but how secure is a Mini with reasonable security controls turned on? I have cable modem installation scheduled today, but don't get my new wifi router until Friday. So, I'm debating hooking a Mini straight to the cable modem for a few days. If reasonably secure, what are suggestions to harden it to outside attacks, for example, turn firewall on, turn off filesharing/remote access/etc. Any links would be appreciated as I'm sure someone, somewhere has already written up similar solution(s).
