Address Resolution Protocol (ARP) Poisoning 

Address Resolution Protocol (ARP) Poisoning 

ARP Poisoning can be defined as the cyber-attack in which the attacker exploits the lack of authentication in the ARP protocol. The attacker transmits infected ARP messages to default gateway over a local area network (LAN) The main objective of the attacker is to connect its MAC address with the IP address of the target computer. As a result, data traffic reaches the hackers computer first instead of the original destination and results in loss of data integrity and compromising security. ARP attack is easy to perform as ARP protocol is not designed for security purpose and does not support authentication. ARP is designed to translate an IP address into a MAC address.
