Dns query traffic monitoring and processing method and apparatus

PURPOSE: A method for monitoring and processing domain name service(DNS) query traffics and an apparatus for the same are provided to improve attacking detection rate and to reduce the failure of detection. CONSTITUTION: An information processing thread(310) collects information by monitoring DNS query during a time slot-based monitoring period. A time thread(320) informs the termination of the monitoring period. A traffic dividing thread(330) divides the attacks of traffics with respect to DNS query based on the collected information. An attach blocking thread(340) blocks the attacks of the traffics.
