Parameters
client-verify: Adds the victim IP addresses to the protected IP list for HTTP client verification. If
HTTP client verification is enabled, the device provides proxy services for protected servers.
drop: Drops subsequent HTTP packets destined for the victim IP addresses.
logging: Enables logging for HTTP flood attack events.
Usage guidelines
For the HTTP flood attack detection to collaborate with the HTTP client verification, make sure the
client-verify keyword is specified and the HTTP client verification is enabled. To enable HTTP client
verification, use the client-verify http enable command.
Examples
# Specify drop as the global action against HTTP flood attacks in the attack defense policy
atk-policy-1.
