ARP Poisoning: Understanding the Threat and How to Prevent I

ARP poisoning, also known as ARP spoofing, is a type of cyber attack in which an attacker intercepts and manipulates network traffic by sending fake Address Resolution Protocol (ARP) messages. ARP is a protocol that is used to map IP addresses to MAC addresses on a network, and ARP poisoning involves sending fake ARP messages to trick devices on the network into sending traffic to the attacker instead of the intended recipient.
