The correct answer is A. ARP.
A Man-in-the-Middle (MITM) attack is a type of cyberattack where the attacker intercepts the communication between two parties. In most MITM attacks, the attacker intercepts the communication and masquerades as one of the parties, thereby gaining access to sensitive information.
Address Resolution Protocol (ARP) is a protocol used to map a network address (such as an IP address) to a physical address (such as a MAC address). In an ARP MITM attack, the attacker sends fake ARP messages to the network, falsely associating the attacker's MAC address with the IP address of the victim. When the victim sends packets to the attacker's IP address, the packets are sent to the attacker's MAC address instead, allowing the attacker to intercept and manipulate the communication.
SIP (Session Initiation Protocol) is a protocol used for initiating, maintaining, and terminating real-time sessions that involve video, voice, messaging, and other communications applications and services. SIP is commonly used in VoIP (Voice over Internet Protocol) systems. While SIP may be vulnerable to attacks, it is not commonly used in MITM attacks.
FTP (File Transfer Protocol) is a protocol used for transferring files over the internet. While FTP may be vulnerable to attacks, it is not commonly used in MITM attacks.
SCP (Secure Copy Protocol) is a secure file transfer protocol that uses SSH (Secure Shell) for encryption and authentication. While SCP may be vulnerable to attacks, it is not commonly used in MITM attacks.
In summary, ARP is the protocol most commonly used in MITM attacks because it is used to map IP addresses to MAC addresses, and the attacker can intercept and manipulate these mappings to intercept and manipulate communication.
