Flood attacks

A flood attack is a type of Denial of Service attack. During a flood attack, a rogue wireless device attempts to overwhelm

the resources of other wireless devices by continuously injecting management frames into the air. For example, a rogue

client can repeatedly send association requests to try to overwhelm APs that receive the requests.

The threshold for triggering a flood message is 100 frames of the same type from the same MAC address, within a

one-second period. If WSS Software detects more than 100 of the same type of wireless frame within one second, WSS

Software generates a log message. The message indicates the frame type, the MAC address of the sender, the listener

(AP and radio), channel number, and RSSI.
