If network security on the average Internet-connected desktop is a serious concern, how much more so should it be in situations where a Wireless LAN (WLAN) is involved. Wireless Routers and Access Points are shipped with the most lax security options possible in order to facilitate easy installations (with the exception of Microsoft, who does require WEP). The problem is that users have to take the next step and start locking their WLAN down after it's setup, but many don't for a variety of reasons. Hence today's Wireless Security Practicum.
You might wonder why anyone would even want access to your network. In most scenarios, your wireless network provides perpetrators with two things: 1) access to your local network (the computers connected up in your house), which if unsecured means access to your data, and better yet, 2) access to the 'net. 11Mbits/sec isn't a bad little heist for someone who wants to spend all night downloading pr0n from your connection, or perhaps they'd rather mail bomb the government or something. It's no matter--just don't be an easy target. We're gonna help.
This article is aimed at covering the major techniques for reducing your WLAN's vulnerabilities using the tools and methods available to your standard home user or administrator in a small networking environment. If you have a WLAN, this is for you.
