SonicWall addresses ICMP flood attacks by implementing rate limiting for ICMP Echo Request packets, often referred to as 'ping' requests. Advanced features can also be configured to drop invalid or malformed ICMP packets, which are common vectors for these types of floods, thereby preserving WAN resources.
