In the comment box:<p>"Hi - Lockheed here, Head of the NOC at DefCon. I invite any and all to use the secured WiFi at DefCon. I know I can't convince the ultra-paranoid to use it; that's fine. However, we do go through efforts to provide a (relatively) safe network environment for a reason. The open Wifi at DefCon is meant to be a sandbox - hack and be hacked. Our secure segment is designed such that we (DefCon NOC staff) work to help secure your data session; We don't let anyone sniff the traffic, we don't allow client-to-client communication. We're just trying to make it a little easier to come to DefCon and enjoy the show."
