What is ARP spoofing?

1. A method of capturing network traffic

2. An attack that diverts communications

3. A technique for monitoring network performance

4. A form of encryption protocol

The correct answer is: An attack that diverts communications

ARP spoofing is an attack that diverts communications by sending false Address Resolution Protocol (ARP) messages over a local area network. In this process, the attacker associates their MAC address with the IP address of another device, commonly the router or a target machine. As a result, traffic intended for the legitimate device is redirected to the attacker's device instead. This redirection can allow the attacker to intercept, modify, or block data, thereby compromising the integrity and confidentiality of the communication. The other options do not accurately describe ARP spoofing. Capturing network traffic can occur as a result of ARP spoofing, but it is not the defining characteristic of the attack; it is merely one of the possible consequences. Monitoring network performance is unrelated to ARP spoofing, as this involves the assessment of network efficiency and health rather than manipulation of traffic. Additionally, ARP spoofing is not associated with encryption protocols, which are designed to secure data rather than divert it.
