Gratuitous Address Resolution Protocol Protection
Gratuitous Address Resolution Protocol (GARP) Protection protects the
IP Phone 1150E from GARP Spoof attacks on the network. In a GARP Spoof
attack, a malicious device on the network takes over an IP address (usually
the default gateway) by sending unsolicited (or Gratuitous) ARP messages,
thus manipulating the ARP table of the victim’s machine. The malicious
device launches a variety of attacks on the network, resulting in undesired
traffic routing. For example, a GARP attack can convince the victim machine
that the malicious device is the default gateway. In this scenario, all traffic
from the victim’s machine flows through the malicious device.
