Okay, folks, it is time once again to review the state of today's wireless 802.11 (also known by the marketing term, WiFi) security. This has been documented time and time again, but it has recently became clear to me that it apparently isn't sinking in. One of my goals with this blog is to try and educate friends and family, so I thought I would write something up that is in plain English and implore you to think about your wireless situation at home.
I was recently on vacation in a small town in Idaho when I fired up my laptop and found no fewer then six wireless networks within range. A couple of things surprised me about this. The first being that there were six(!) networks in my immediate vicinity in a town with a population of 4,000. I am not used to seeing this kind of coverage in the smaller mountain towns that I've visited. The second, and probably more, surprising aspect of this was that all of them were secured! That's right, none of them were set to allow open access, nor did they have the all-too-familiar network name "linksys" or "default".
Unfortunately, they had all used WEP as the means for securing their network. This is horribly insecure and merely serves as a means to keep the honest people honest. Perhaps, that is all the owners were after, but I would like to encourage you to go a step farther in securing your own home network. It's really not that hard and will take 10-15 minutes, tops. If you haven't already, please read my post regarding the dangers of using WEP.
If you are still reading, then perhaps I've convinced you to convert your network from WEP or open to WPA. If that is the case, read on...
Lesson #1) Do not buy an access point (also known as "router", "wireless hub", or just plain "wireless"), take it home, plug it in, and just start using it. This is what we would call the "default" or open access. It comes with an instruction manual for a reason. Use it! :)
