Symptoms
Currently when Device ID is enabled, the BIG-IP system counts stateful anomalies on both IP and Device ID. When a client has a proxy (without XFF), and many requests arrive with the same IP, this can cause false positives
Impact
False positives may occur in case of a proxy without XFF
Conditions
- Bot Defense profile is attached to a virtual server.
- Bot Defense profile has "Browser Verification" set to "Verify After Access" or "Device ID Mode" set to "Generate After Access".
Fix Information
Stateful anomalies are no longer counted on IP when Device ID is enabled
