Abstract
Disclosed is a DDoS attack detection and response apparatus. The DDoS attack detection and response apparatus comprises: a receiver unit receiving HTTP requests from a client terminal which is characterized as an IP address; a data measuring unit computing the number of HTTP requests by IP and the number of URIs per HTTP over a certain time period; a DDoS discrimination unit comparing the number of HTTPs per URI with a threshold value and defining an access of the client terminal having the IP address as a DDoS attack when the number of HTTPs per URI is larger than the threshold value; and a blocking unit blocking packets from the IP address when the DDoS discrimination unit detects a DDoS attack.
