Things we can't currently fix • Open networks are insecureable • There is no way to maintain trust – no unique information in an open network • WPA-PSK only provides trust when the PSK is unknown, no good for public networks • WPA-EAP needs cert chain, difficult and dangerous 68
Active defense • Actively defend via injection of packets • Use the same attacks • Difficult to enforce in shared airspace, unless you're the only occupant in a building... • Kismet doesn't, but could with plugins 69
