C&C domain name identification method based on domain name feature

The invention discloses a C&C domain name identification method based on domain name features. The method comprises the following steps: S1, generating a quantitative index for judging domain name categories specific to given domain names based on the qualitative features of the domain names; S2, randomly extracting a part of domain names from the given domain names to be input into a training data set, inputting the rest domain names into a testing data set, and generating a domain name category judging model based on the training data set with a decision tree integration algorithm; S3, judging the domain name categories of the rest domain names in the testing data set with the generated domain name category judging model, comparing the domain name categories of the rest domain names in the testing data set with the practical categories of the rest domain names, and calculating the prediction performance index of the domain name category judging model; S4, correcting the domain name categories judged by the domain name category judging model; and S5, generating the statistics result of a single domain name based on the corrected domain name categories. Through adoption of the C&C domain name identification method, a C&C domain name can be found accurately, and the high landing property, feasibility and comprehensibility of the model are enhanced.
