摘要

The web application firewall device includes a determination unit for determining whether or not the request is an invalid parameter and an analysis receiver. The web application device includes a controller for determining whether or not the request is a valid parameter and a response generation unit for generating a response. The determination unit updates the data for filtering the parameter based on the invalid information. The response generation unit selectively generates these responses including invalid information and valid information to transmit to the web application firewall device.
