Abstract

The invention relates to a machine learning type domain name system security defense method. The method includes the following steps: performing characteristic contrast on data included in received domain name resolution requests and learning result data obtained by historical domain name resolution record operation according to given regulations; resolving for the characteristic-conformed domain name resolution request to generate a domain name resolution record; responding to the corresponding domain name resolution request with the domain name resolution record. Besides, the invention further discloses a device corresponding to the device according to modularized thinking. By implementation of the method and the device, a DNS (domain name server) can understand DNS attacks more intelligently, operation efficiency is optimized, and the function of a disaster recovery system is achieved.

Description

technical field [0001] The invention relates to Internet security technology, and relates to a machine learning type domain name system security defense method and device. Background technique [0002] Domain Name System (DNS) is a basic Internet protocol. Compared with various WEB services with relatively complete prevention measures at present, the defense based on DNS is still weak, and it is easy to be attacked by hackers. Hackers can implement DNS attacks in many ways, among which DNS amplification attack is a new type of denial of service attack. [0003] The characteristics of DNS itself determine that it can be used as an "attack amplifier" to carry out DDOS attacks. One is the weakness of the DNS protocol itself, so that both the query request message and the query response message can be forged, and the network attacker can forge the attacked host to send a DNS query request to the DNS server through a false source address, and at the same time hide the attacker’s...
