Re: ARP spoofing attacks

[Matthias Vallentin <x () pi-cubiq de>]

you can't enable port-security on access points (wlan), can you? how can you protect yourself again wireless arp cache 
poisoning? once an attacker is associated with the network, he can sniff all the traffic and perform arp-attacks and 
put himself in a MITM-position...
would a strong authentication be a solution for this problem?

greetings,

matthias
