The log message in the AFM DoS Sweep & Flood Vectors could contain IP addresses which have not reached the attack threshold.


Misleading logs saying that innocent IPs are bad IPs.


If AFM DoS Sweep & Flood vectors are configured and attacks have been triggered and we have non-attacking IPs also sending us similar traffic below the threshold, then they could also be logged as attacking IPs.


Do not configure the AFM DoS Sweep & Flood vectors.
