Re: att wireless users
I hide the SSID and use MAC adrress. I beleive that even the small things help to harden your secutiy. If you know a lot about routers and confguring them great, but the average user doesn't and they really don't want to. So to give someone a tip that may help their security, in my book, is a good thing.
And if you don't care who hops on, all the power to you, I do care.
If someone wants on your network bad enough, they are going to get on it, but if you make it more difficult, most will try to find something easier. It's like the little lock on your front door, it's not going to stop a determined person, but will turn most away.
