Abstract

The invention discloses a network intrusion data detection method. The method comprises the following steps: acquiring real data in a network as target data; according to the category of the target data, extracting all features of the target data and performing preprocessing to generate a first feature set; judging whether the relevance between each feature in the first feature set and the intrusion data is irrelevant or not; if not, removing the features to generate a second set of features; determining the importance degree of the target feature in the second feature set; judging whether thetarget feature is a redundant feature or not according to the importance degree; if yes, removing the target features to generate a target feature set; and detecting intrusion data in future networkdata according to the target feature set. According to the invention, the detection efficiency and accuracy are improved, and the security of network data is better ensured. In addition, the inventionalso provides a network intrusion data detection device, equipment and a medium corresponding to the method.

Description

technical field [0001] The invention relates to the field of network security, in particular to a method, device, equipment and medium for detecting network intrusion data. Background technique [0002] With the rapid development of the Internet, there are more and more cases of being accessed by malicious networks, and the network intrusion methods used are becoming more and more concealed and silent. In order to prevent malicious intrusions in the network from destroying, changing and leaking the data in the network system, so that the network system can run safely and reliably, using intrusion detection technology to perform security detection on network access has become an indispensable guarantee for network security. links. [0003] In the prior art, a feature set for abnormal data is established by collecting data in the network; when network data matching the feature set is detected, the access is defined as an intrusion access. However, due to the increasing scale...
