wireless insecurity : wep hacked in 3 minutes
At a recent ISSA (Information Systems Security Association) meeting in Los Angeles, a team of FBI agents demonstrated current WEP-cracking techniques and broke a 128 bit WEP key in about three minutes. Special Agent Geoff Bickers ran the Powerpoint presentation and explained the attack, while the other agents (who did not want to be named or photographed) did the dirty work of sniffing wireless traffic and breaking the WEP keys
- seperate your wireless network from your lan network with a firewall
- change the default settings and use strong passwords
- update the firmware and use WPA instead of WEP
my opinion is that a network with important and critical data must be nutts to let 'facility' and 'hype' be more important than 'security'. You wouldn't be the first to get hacked by the air, while your wires have different protection layers. It is like the modems where people were bypassing the firewall by using a modem to call in or out.
