Network intrusion detection method and device based on multi-network model and electronic equipment

Abstract

The invention discloses a network intrusion detection method and device based on a multi-network model and electronic equipment, and the network intrusion detection method comprises the steps: obtaining to-be-processed data, and carrying out the preprocessing of the to-be-processed data; carrying out feature extraction on the preprocessed data to obtain a feature vector; respectively taking the feature vectors as input vectors of a plurality of pre-trained classification network models to respectively obtain output probability values of the plurality of classification network models; and splicing the output probability values of the plurality of classification network models into one-dimensional matrix information, taking the one-dimensional matrix information as an input vector of a pre-trained decision model, and judging whether the to-be-processed data is intrusion data or not according to the output probability values of the decision model. According to the network intrusion detection method based on the multiple network models, multiple model algorithms are effectively combined together, and the respective advantages are brought into play together, and the recognition accuracyis improved.

Description

Technical field [0001] The invention relates to the technical field of cyberspace security, in particular to a network intrusion detection method, device and electronic equipment based on a multi-network model. Background technique [0002] With the popularity of the Internet and mobile Internet, more and more people share information through the Internet. While the sharing of network information has brought convenience to people's lives, network security issues have become increasingly serious. The intrusion detection system is an important part of the network security system. Different from passive detection systems such as firewalls, it can actively detect potential intrusion behavior information, so as to provide users with more comprehensive information protection. With the improvement of hacker technology, intrusion methods and methods have become diversified and complicated, and higher requirements are put forward for the performance of all aspects of intrusion detection ...
