How-to: Secure a Wireless LAN

Filed under: security — Tags: ,

In the past few weeks I have had a couple of people ask me the question “How secure is a wireless network?” I have also seen a couple of posts on Craigslist asking about this. It turns out that most wireless networks are not very secure I just browsed my own wireless utility and found that there were five different networks (besides my own) that I could see from my computer. Two of them had no security at all. Even though I didn’t try I’ll bet that not only could I use their networks and I could probably get into their computers, too. If I had all of the tools handy to me that the bad guys have I’m sure that I could cause some real trouble just by driving down any street with my laptop on.

It turns out there are some simple steps to make your network more secure. Usually when someone asks me I just point them to this post on Daily Wireless. It answers the questions that I had and some that I didn’t even know that I had. It also tells you why these steps are necessary.
