ARP Spoofing Prevention

ARP spoofing, also known as ARP poisoning, is a method to attack an Ethernet network which may allow an attacker to sniff data
frames on a LAN, modify the traffic, or stop the traffic altogether (known as a Denial of Service – Dos attack). The principle of
ARP spoofing is to send the fakes, or spoofed ARP messages to an Ethernet network. Generally, the aim is to associate the
attacker's or random MAC address with the IP address of another node (such as the default gateway). Any traffic meant for that IP
address would be mistakenly re-directed to the node specified by the attacker.
