: Attackers send falsified ARP messages to a local network to link their MAC address with the IP address of a legitimate server or gateway. This allows them to intercept, modify, or stop data in transit, often facilitating Man-in-the-Middle (MitM) attacks.

: While often associated with switches, this attack fills a switch's CAM table with fake MAC addresses, forcing it to act like a hub and broadcast all traffic to every port, where an attacker can sniff it. Common Mitigations

These protocols are foundational to local area networks (LANs) but lack built-in security, making them common targets for network-level attacks:
