Network Data Feature Selection in Detecting Network Intrusion using Supervised Machine Learning Techniques

Network attacks have become necessary in today’s time due to increased network traffic. To determine whether network traffic is normal or anomalous a supervised machine learning system is developed. A network intrusion detection system (IDS) is a must-have piece of a security system. This proposed study aims to discover new patterns automatically from substantial quantities of network data, reducing time manually compiling intrusion and normal behavior patterns. The best model in terms of detection success rate was discovered using a supervised learning algorithm and feature selection method. AdaBoost outperforms Neural Network, kNN, and Naive Bayes in supervised machine learning with feature selection in this study, with a detection accuracy of 100.00%, 99.30%, 91.60%, and 99.70%, respectively. The Network Intrusion Detection dataset is used to classify network intrusions to evaluate the study and it has also been used in past studies. On the other hand, the proposed model proved to be more effective than other studies in terms of intrusion detection. The proposed approach can be used in various fields, including finance, health, and transportation. Furthermore, additional parameter tuning could be added, and different feature selection techniques could be used to improve the performance of the classifiers.
