What is Address Resolution Protocol Spoofing?
Address resolution protocol spoofing is a strategy that involves sending a counterfeit ARP or address resolution protocol message to an Ethernet local area network. The main function of ARP spoofing is to redirect traffic from one IP address to the MAC address of the originator of the spoof. The process works by tricking the Ethernet network into picking up on the counterfeit address and routing traffic to terminate with the spoofed address rather than being directed to the genuine IP address. Once the traffic is routed through the address resolution protocol spoofing process, the originator of the fake address has two options. First, the received data can be evaluated and then passed on to the real destination. In this option, the data is not altered in any manner. This approach is known as passive sniffing. The second option that results with address resolution protocol spoofing involves receiving the intercepted data and altering it in some manner. The altered data is then forwarded
