Abstract

The present invention provides a malicious domain detection method and device based on intelligence analysis. The method comprises the steps of obtaining communication data in a network; analyzing the communication data to extract the IP of a source host, domain names searched by the source host query and time of searching the domain names; a domain risk level database is searched to determine the domain names searched by the source host is in the domain risk level database; if the domain names searched by the source host is in the domain risk level database, a risk level result corresponding to the domain names is taken out from the domain risk level database and presented; and if the domain names searched by the source host is not in the domain risk level database, evaluation is carried out on domain risk levels and the risk level evaluation result is presented. The risk level evaluation result includes search engine recording status analysis and Internet archive analysis. The malicious domain detection method and device provided by the invention can precisely detect unknown malicious domains.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and device for detecting a malicious domain name based on intelligence analysis. Background technique [0002] With the rapid development of network technology and the arrival of the network age, the vast and rich resources contained in the network have brought a lot of convenience to human society. However, while people's lives are becoming more and more dependent on the Internet, network security incidents driven by interests are emerging one after another. Seriously affected the normal use of the network, but also brought great harm to all sectors of society, so the detection of these events is extra important. [0003] The domain name system is one of the important infrastructures of the current Internet, and a large number of network services rely on domain name services to carry out. Domain Name Resolution Service (DNS) maps abstract IP addresses into ea...
