PENERAPAN METODE EXTREME GRADIENT BOOSTING UNTUK DETEKSI MULTI-CLASSIFICATION SERANGAN SIBER
In the developing digital era, cybersecurity threats are increasing. One of the solutions commonly used in securing networks is the Network Intrusion Detection System (NIDS). To improve the performance of NIDS, this study applies the Machine Learning (ML) method, namely the Extreme Gradient Boosting (XGBoost) method, because it is considered to have high performance and its ability to handle complex and imbalanced data. Therefore, this study aims to evaluate the performance of the XGBoost algorithm in detecting various types of cyber attacks using five benchmark datasets commonly used in intrusion detection systems, namely NSL-KDD, UNSW-NB15, CIC-IDS2017, CSE-CIC-IDS2018, and ToN-IoT. In this study, XGBoost is used as the main algorithm to detect and classify various types of cyber attacks in the form of multi-class classification. Therefore, in this study has stages of pre-processing, feature selection, and hyperparameter tuning optimization. Also, several main evaluation metrics are used such as accuracy, precision, recall, F1-score, confusion matrix, and ROC-AUC.
