Re: ARP spoofing attacks

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,

The best way i know of thus far is to enable "port security" in some form
or another.  Cisco switches can lock the port down to only allow a certain
MAC.  If you spoof...the port drops.

Arpwatch and a NIDS can also watch for this type of traffic...but it is
spotty and requires the architecture/heirarchy to be setup correctly for
it to work properly.

Cheers,
-Chris
