What is the primary technique used in ARP poisoning?

• A. Flooding the target machine's ARP cache with forged entries
• B. Injecting malicious software via network protocols
• C. Hiding the source of network packets
• D. Disabling the firewall on the target machine

Answer: (A)

ARP poisoning primarily involves sending falsified Address Resolution Protocol (ARP) messages onto a local area network. This technique aims to associate the attacker's MAC address with the IP address of a legitimate computer or server on the network. By flooding the target machine's ARP cache with these forged entries, the attacker can intercept, modify, or stop data intended for the legitimate IP address, effectively redirecting network traffic. This method is particularly effective in local networks where ARP requests and responses are used to map IP addresses to MAC addresses. Since ARP does not include strong authentication mechanisms, it is susceptible to such attacks, allowing an attacker to gain unauthorized access to network communications. The other methods mentioned, such as injecting malicious software via network protocols, hiding the source of network packets, or disabling the firewall, do not accurately describe the key strategy employed in ARP poisoning, which specifically focuses on manipulating ARP-related traffic to deceive network devices about the identity of the communicating machines.
