MAC Flooding Definition: MAC Flooding is a cyber attack where the attacker floods a network switch with spoofed MAC addresses, causing the switch to become overwhelmed and potentially leading to a denial of service.
MAC flooding is a cyber attack where an attacker floods a switch with spoofed MAC addresses, causing the switch to overflow its Address Resolution Protocol (ARP) table. This results in the switch entering a fail-open mode, treating all incoming traffic as broadcast traffic, allowing the attacker to intercept and modify network packets.
