I have written several posts with regards to securing your wireless network connection. In many of those posts I have talked about choosing WPA over WEP, and briefly explained why I do that. In a post titled Network Glossary of Terms I provided a simple definition for both security protocols.
I have decided to expand on those definitions by providing a more information post about WEP and WPA. Hopefully, this post will help you better understand how a wireless network is secure.
