Embodiment Construction

[0046] The working principle and technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation.

[0047] Dimensionality reduction technology, as a means to improve computing performance, can be used as a preprocessing step in machine learning algorithms to eliminate irrelevant features and retain the most relevant features. In practice, there are two ways to re-determine the number of attributes in a dataset. The first approach is feature selection, which retrieves a subset of the original features without modifying data attributes. Feature selection can be divided into three categories by type: filters, wrappers, and embedding methods. Filter methods select features based on their intrinsic properties, i.e. regardless of classifier performance. In the second feature extraction method new features are created by generating new combinations of original features.

Abstract

The invention discloses a network-oriented intrusion data detection method, which comprises the following steps of: firstly, performing attribute dimension reduction on network flow data, and then inputting the data into a data detection model; and enabling the detection model to process the network flow data according to a decision rule and detects intrusion data. According to the invention, high-efficiency, high-precision and low-false-alarm intrusion detection can be realized, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of network intrusion detection and feature dimension reduction, in particular to a network-oriented intrusion data detection method. Background technique [0002] Firewalls, malware prevention, data encryption, and user authentication, which still do not provide complete protection against contemporary cyber attacks, make up a necessary but incomplete set of system tools to protect computers and networks from today's attacks. Intrusion detection systems and other security systems can complement each other. In general, an intrusion detection system is a proactive system that constantly monitors and analyzes network traffic to determine if there are deviations from expected behavior. The first approach to intrusion detection systems is signature-based intrusion detection, which classifies pre-defined attack signatures by analyzing network packets. Therefore, this method cannot identify new attacks. [0003]...
