Re: Stopping Arp poison attacks

["Ivan ." <ivanhec () gmail com>]

Peter,

On the networking side, in the Cisco world you can do a couple of
things to mitigate the risk of this type of attack.

Attack                                         Mitigate
Spoofing the DHCP server               DHCP Snooping and Port Security

Spoofing the default gateway          Dynamic ARP Inspection (DAI)

Spoofing an IP address                     IP Source Guard
