ICMP Flood
An ICMP flood sends excessive ICMP traffic that consumes bandwidth or processing resources.
Mechanism
The service or network spends resources receiving and processing more ICMP messages than normal.
Indicators to watch
ICMP packet-rate spikes, bandwidth consumption, elevated device CPU, and changes in echo request/reply ratios.
Concept diagram
Defensive controls
Rate-limit ICMP where appropriate, filter unnecessary traffic, use upstream DDoS controls, and maintain baseline telemetry.
Recommended security control
Firewall / flow monitoring
Use controlled lab traffic only.
