Thanks for checking into that. I strongly advise you to turn on your firewall in OS X to "Block all incoming connections". You can do this in System Preferences > Security > Firewall and clicking on the "Advanced" button. You will see a check box for what I am recommending. Do that straight away. Before you even finish reading this message. Once that is done, you should buy a simple router. You don't need Wi-Fi (unless you plan on getting other machines including an iPhone or the like), and you don't need Gigabit switching. Basically you need the simplest, cheapest router available. They all do something called Network Address Translation (NAT) and part of that process really seals of your local network (in this case your local network is composed of your Mac and half of the router) from the external network (which includes the other half of your router and the big bad world). Again, I don't wish to alarm you, as it did seem like Virgin Media were providing NAT just a bit further out from your location. So it may only be a small chunk of the big bad world that can probe and scan your Mac. As an experiment, put your Mac to sleep and watch to see whether the recv light on your cable modem flickers. Every time it does, that means that something from the outside is trying to scan or probe whatever you might connect to that cable modem. I get several such probes of per second. It's a normal part of being connected to the Internet. Fortunately, a router doing NAT takes care of all of that for you, so those never get very far. (I have actually configured my router to log those probes, and I send of a summery of those logs to http://www.dshield.org/reports.html ) The overwhelming majority of those automated probes are looking for Windows vulnerabilities, but that doesn't mean that they all are. I'll leave it to others who are more local to you to make recommendations about where to get a router. Just don't let someone sell you more than you need.

FWIW I haven't actually been able to catch the Recv light on my modem flickering when my Mac is shut down or sleeping. That's not to say it doesn't occasionally, of course. -- Mike Lane UK North Yorkshire email: mike_lane at mac dot com
