Security Expert Bruce Schneier wrote a commentary on Wired yesterday where he admitted that he was using an Open Wi-Fi and that he could not see what was wrong with doing so. He refused to accept security reasons because he said that the computer had to be secured as well and that an Open Wi-Fi would essentially be the same as using Wi-Fi on airports or Internet cafes.

The article wireless security attacks and defenses begins with a example how people who are new to the wireless world run their wireless devices carelessly and thus invite others (with more knowledge) to exploit this weakness. Those people run for example wireless routers at factory defaults because they don´t know better, they think the device is safe the way it´s preconfigured.

A friend of mine moved to a new house and had to change his internet provider as well. The room with the computer and the one with the phone line were not close to each other and he decided to buy a wireless lan router and use it to connect to the internet.

We had to do a scan of the surroundings of course and found lots of unsecured wireless lan networks. I don´t know why people keep these unsecured, maybe its laziness, maybe they simply don´t know the risks involved. Its like leaving your doors open when you leave your house. Lots of things can happen..
