Comprehensive performance evaluation of intrusion detection model based on radar chart method

In order to solve the problem that the traditional performance evaluation methods can not accurately evaluate the performance of intrusion detection model, a comprehensive performance evaluation method of intrusion detection model based on radar chart method is proposed. According to the five basic evaluation indexes of accuracy, precision, recall, specificity and F1 score, a comprehensive performance evaluation method of intrusion detection model based on radar chart method is proposed. Finally, on the NSL-KDD dataset, the comprehensive performance of five common machine learning models is analyzed by radar chart method. The simulation results show that the comprehensive performance evaluation method of the intrusion detection model based on the radar chart method can comprehensively and objectively reflect the comprehensive performance of the intrusion detection model, and provide a theoretical basis for the performance analysis, optimization and decision-making of the intrusion detection model.
