Embodiment Construction

[0039] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited.

[0040] figure 1 Shows the CVAE-GAN network structure;

[0041] (1) Input stage

[0042] (1) The input of the CVAE-GAN algorithm must be a two-dimensional image, and the sequence data with a low detection rate in the original data set needs to be converted into a two-dimensional image. Therefore, the training set is converted into a matrix format of 128×128 images by reducing the loss of quantization and normalization.

[0043] (2) Define a batch of samples x r and category c r , which is required to conform to the probability distribution of real data.

[0044] (2) Encoder E stage

[0045] In the CVAE-GAN model mentioned in the present invention, the encoder network E uses GoogleNet, and the category information and images are fused in the last fully connected layer of the network, and x r , c...

Abstract

The invention discloses an intrusion detection method based on CVAE‑GAN, which relates to the technical field of intrusion detection and includes the following main steps: (1) performing data enhancement; (2) performing data preprocessing; (3) performing autoencoder network characteristics (4) Intrusion identification; (5) Abnormal handling. The invention effectively solves the problem that the intrusion detection system has too low detection rate for certain types or several types of data.

Description

technical field [0001] The invention relates to the technical field of intrusion detection, in particular to an intrusion detection method based on CVAE-GAN. Background technique [0002] With the increasing popularity of application devices connected to the Internet, more and more services need to be completed by relying on the network, which brings increasing users' attention to network security performance. Due to the continuous iterative development of network attack methods and attack scales, passive security detection systems such as traditional intrusion detection mechanisms are difficult to stop the endless attacks. Subsequently, researchers studied intrusion detection as an active defense technology to make up for the shortcomings of traditional security detection technology. Active defense and response technology has also begun to attract the attention of researchers at home and abroad. [0003] Intrusion attacks seriously threaten personal privacy information and...
