Affected Product(s):
BIG-IP ASM
Known Affected Versions:
12.1.0, 12.1.0 HF1, 12.1.0 HF2, 12.1.1, 12.1.1 HF1, 12.1.1 HF2
Fixed In:
13.0.0, 12.1.2
Opened: Apr 19, 2016 Severity: 3-Major
Problem: 100% accurate detection may not help to prevent an attack It's necessary to protect BIG-IP CPU utilization during attack - for BAD actors (in addition to shunlist) and for unknown IPs. This mechanism should allow bad actors detection and keep CPU utilization in reasonable limits.
Service impact due to BIG-IP CPU high utilization
High BIG-IP CPU utilization during (D)DOS attack
No workaround
Added additional CPU protection during a (D)DOS attack
