Wireless Networks are becoming more and more common these days and lots of people are ignoring the fact that they have to secure their wireless lan. Seth Fogie from informit estimates that about 40-50% of all wireless lan users use no protection at all for their network.

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..

Only a few days ago I wrote a first small article about true crypt and recommended it. Back then I bought a usb 2.0 hard drive with 300 GB capacity and encrypted its entire partition with true crypt. This was done to test the programs functionality but also to see if it would slow down my main computer (athlon 64 3000+, 1 gb ram).
To my great suprise it did not slow down the pc and I decided to expand the encryption to cover all my hard drives. Let me tell you why and how i did this and why you should also be considering this.
