Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] See figure 1 As shown, a terminal feature extraction method based on hostname data in an embodiment of the present invention includes:

[0040] Step S1, obtaining original hostname data information;

[0041] The acquired original hostname data information should be as much as possible. The more original hostname data information, the greater the significance of extracting terminal features, and the higher the value of the extracted termin...

Abstract

The invention provides a terminal feature extraction method based on hostname data. The method comprises the following steps: a feature blacklist generation step: extracting unique identifier data inthe hostname data, and forming a feature blacklist list; and a feature model data generation step of deleting the hostname data according to the feature blacklist to form a model data list. When terminal feature extraction is carried out on a large batch of hostname data, the feature extraction workload is reduced, the feature extraction efficiency is improved, the feature coverage degree is improved, and meanwhile the feature recognition rate is greatly increased.

Description

technical field [0001] The invention relates to a terminal feature extraction method, in particular to a method for extracting a terminal model based on a hostname short text. Background technique [0002] hostname is the hostname, and each network device has a corresponding hostname for easy distinction. [0003] In the terminal big data analysis process, part of the terminal feature information comes from the hostname data in the DHCP message, because most of the hostname data contains terminal model information, and the information is highly reliable, providing a solid foundation for terminal feature analysis. [0004] One of the existing technical solutions: [0005] Manually capture the DHCP packet information sent by different devices, extract the hostname data, and then manually analyze to extract the characteristic information. Disadvantages: low efficiency, limited equipment, limited feature extraction, low coverage, delayed feature update, and low feature recogni...
