Problems solved by technology

Since temporary domain names are normal domain names used in regular Internet services, and their characteristics are quite different from those of bad application domain names and abnormal domain names, neither of the above two domain name identification technologies can effectively identify temporary domain names.

Embodiment Construction

[0037] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

[0038] First, the working principle and technical concept of the present invention need to be explained.

[0039] Temporary domain names usually have the following characteristics:

[0040] (1) The frequency of use of the domain name and most of the domain names in the domain is close to 0;

[0041] (2) The leftmost fields of this domain name and most of the domain names in the domain are randomly generated strings.

[0042] The present invention identifies the temporary domain name based on the above features.

[0043] The temporary domain name identification method provided by the present invention is as attached figure 1 shown.

[0044] Querying the database based on a domain name includes the following steps:

[0045] Read the domain name query datab...

Abstract

The invention provides a temporary domain name identification method based on a domain name query database. The method comprises the following steps that the domain name query database is read, and a domain name query tree is established according to domain name query request information; feature extraction is carried out on all sub nodes except lead nodes in the domain name query tree according to the feature of a temporary domain name, and the domain name features of the sub nodes are obtained; all the sub nodes except the leaf noise in the domain name query tree are clustered according to the extracted domain name features, and multiple subsets are obtained; a subset in which the number of sub nodes is lower than a threshold is selected from the subsets and serves as a suspected temporary domain subset, and a suspected temporary domain name list is output according to the suspected temporary domain subset. The invention also provides temporary domain name identification system.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a temporary domain name identification method and system. Background technique [0002] As a new type of domain name, temporary domain names have been widely used by some specific Internet services (such as virus scanning, instant messaging, etc.) in recent years. Some fields in such domain names are usually randomly generated by a specific algorithm, and the volume is huge, but the overall frequency of use is very low, which is somewhat similar to temporary use. Although such domain names are normal domain names used for regular Internet services, the appearance of a large number of temporary domain names will inevitably have a great impact on the working efficiency of domain name services (especially the caching service of the recursive domain name server). Therefore, it is necessary to specifically discover and identify such domain names, so that domain name service prov...
