Today's the 4th of July so I'm throwing out a quick post since it's been a few days, but I hope all my readers will be happy with another informational piece about securing your own network since, after all, that's what netsec is about! Below is a simple guide to getting the most security out of your network to protect your information and the users of your network's information. Setting up your router encryption: If you've read my WEP/WPA2 cracking guide , then you understand how fragile WEP encryption is. In my tutorial I also explained how to crack WPA1/2 passwords, but explained that the passkey must be in the dictionary that you specified whilst entering the "aircrack" command. When you're selecting which encryption to use, don't even consider WEP. It can be broken in 30 seconds on a half-decent computer. I've successfully broken WEP in under two minutes sitting in a bathroom on a small dell laptop. As for what TO use, c...

Now that you have hopefully installed the Aircrack-ng suite and familiarized yourself with some basic Linux commands, we can start cracking WEP and WPA1/2 networks to see the differences in securi ty  Wired Equivalent Privacy  (WEP) and Wi-fi Protected Access (WPA) provide.

As my first "real" post, I'll explain the basics to installing an important suite that I use quite often and is one of the most important tools to pentesting networks called Aircrack-ng (ng stands for new generation, like IPng or IPv6). I use Ubuntu Backtrack 5 which comes preloaded with the aircrack-ng suite, but I'll explain how to install and configure this on a fresh Linux computer or laptop for those who aren't strictly into netsec and want to start or have fun with it. Before starting on Linux , make sure you have all the necessary kernel headers and other files necessary to run aircrack. Issue the command "apt-get install build-essential" and add the prefix "sudo" (super user do) before if you are not running as root. This should install all necessary files if you do not already have them, and  you should be ready to begin. Also, the aircrackng suite requires the "openssl-dev or libssl-dev" dependencies (thanks Anon in com...
