Abstract

The present invention provides a feature extraction method, device, and terminal, wherein the feature extraction method includes: obtaining key information of the service to be tested, obtaining PCAP data of the service to be tested according to the key information, and analyzing the service to be tested PCAP data of the service to be tested, obtain at least one feature information to be extracted of the service to be tested, determine the similarity between the at least one feature information to be extracted and the key information, and according to the at least one feature information to be extracted and the The similarity of key information is to extract the characteristic information of the service under test from the at least one characteristic information to be extracted. The solution of the present invention can not only accurately extract the correct feature information of the service to be tested, thereby enhancing the effect of feature extraction, improving the efficiency of identifying corresponding services through the extracted feature information, but also reducing the system overhead caused by querying the database.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a feature extraction method, device and terminal. Background technique [0002] At present, in order to overcome the problem of inefficiency caused by manual participation in extracting business features, business features can be automatically extracted through statistical methods. Since the data based on Hyper Text Transfer Protocol (HTTP) in the network business data occupies the majority, the extraction of business features for HTTP data can greatly improve the efficiency of protocol analysis. Among them, an existing HTTP feature extraction method is: [0003] First, build a frequent information base: analyze the historically collected data of the Process Characterization Analysis Package (PCAP) with tagged services to obtain HTTP feature information, which may include Host, X-Requested- With, Referrer, Cookie and other key domain information, and use HTTP fea...
