seriously, what is so special about this ?
Wow... Someone has a serious lack of Imagination. Here is what is special about this:
These guys manage the most actively hostile network on the planet. Just bringing your laptop/cell phone/PDA within wireless range of this event is asking for trouble. These are the people that put your username/password up on a giant wall of sheep if you choose to use an unencrypted connection for e-mail/web browsing.
Have you considered the challenges of maintaining a server in this environment? You are one giant target for the world's largest collection of black/grey/red-hats in the world. Let's just say that there would be a substantial amount of "iStreet-cred" if you were to 0wn the firewall.
Now, if you read the article, they describe how they setup their wireless network. They keep things very simple and maintain centralized configurations. If you are setting up a network in a potentially hostile environment, their model is a good one to follow. Why? Here are a few reasons:
- Users: 2,226 and 3,801 DHCP leases issued
- 22 Access Points deployed
- Man-in-the-Middle Attacks detected: 215
- DoS Attacks: ~80
- Rouge AP's Detected and Destroyed: 130
- Wireless Bridges Detected: 300
- ARP MAC Spoofing Attempts: 836
- Traffic for the last 30 hours: IN 12gb / OUT 1.2gb
Think your network can handle that? Let's take a look at one of the interesting ones - the Rogue AP's.
The people that run defcon (and many of the attendees) eat these attacks for lunch. These people triangulate wireless signals within a high-em noise environment with enough multipath to give K-9 a headache. They manage to actively seek and destroy rogue AP's (not to mention the ARP spoofing!) while maintaining a healthy network. You don't think that's special!?
Now, what about hardware reliability? Heck, if I had a choice between two pieces of gear and one of them had a "Survived DefCon 2008" sticker on it, I could tell you what I would be picking up. They had a nice Cisco fiber switch (no real surprise) but I have never heard of the Aruba AP's before. I know I'll at least check them out now. Do you not think that exposing battle-proven hardware to electronics-consuming people is special?
Look at the software too. BSD & pf. No real surprise there either. When you want ungodly-stable network filtering - that is the way to go. Don't take my word for it. Heck, don't take BSD's word for it. The setup survived the hacker Olympics with no downtime. THAT is what is special about it.
