Abstract

The invention provides a method and a system for processing DNS (domain name system) water torture attack based on Spark Streaming. The method comprises the following steps of collecting a real-time analysis request on a to-be-protected recursion server, converting the collected real-time analysis request into first information, extracting features of the first information at preset time intervalbased on Spark Streaming, inputting the extracted features of the first information into a pre-established random forest model, identifying the features of the first information based on the random forest model, identifying the water torture attack request in the real-time analysis request, and adding an address of a client network corresponding to the water torture attack request into a blacklistof a fire wall of the system. The method has the advantages that the water torture attack request can be filtered by layers in the recursion server, and can be prevented from entering the recursion analysis phase, so as to play an important role in ensuring the security and stability of an authority server.

Description

technical field [0001] The invention belongs to the technical field of DNS (Domain Name System, domain name system), and in particular relates to a DNS water torture attack processing method and system based on Spark Streaming. Background technique [0002] The domain name system is the cornerstone of the Internet and is responsible for maintaining the information of hosts in the computer network. The security and availability of the domain name system are of great significance. [0003] Waterboarding attack is a kind of DDoS (Distributed Denial of Service, Distributed Denial of Service) attack against domain name system. In a waterboarding attack, the attacker controls the hosts in the botnet to send a large number of domain name query requests to the target authoritative domain name server. The service is terminated due to a large number of query requests, and the waterboarding attack is successful. [0004] Previous detection methods for waterboarding attacks mainly inc...
