ASM DoS detection
Does it mean that DoS would be detected if requests per source IP reached to 200 per second? What's the significance of 40 tps here?
Hi f5rocks,
The ASM DoS feature measures the TPS every 10 seconds and calculates the average for the past hour.
DoS will be detected when an absolute TPS value of 200 is reached, but also when an absolute TPS value of 40 is reached AND an increase of 500% is detected.
Example:
Based on your screenshot DoS will be detected because TPS increased by 700% (> 500%) and absolute value is 600 TPS (> 40 TPS).
