Abstract—Machine learning techniques are widely used to protect cyberspace against malicious attacks. In this paper, we propose a machine learning-based intrusion detection system to alleviate Distributed Denial-of-Service (DDoS) attacks, which is one of the most prevalent attacks that disrupt the normal traffic of the targeted network. The model prediction is interpreted using the SHapley Additive exPlanations (SHAP) technique, which also provides the most essential features with the highest Shapley values. For the proposed model, the CICIDS2017 dataset from Kaggle is used for training the classification algorithms. The top features selected by the SHAP technique are used for training a Conditional Tabular Generative Adversarial Networks (CTGAN) for synthetic data generation. The CTGAN-generated data are then used to train prediction models such as Support Vector Classifier (SVC), Random Forest (RF), and Na├»ve Bayes (NB). The performance of the model is characterized using a confusion matrix. The experiment results prove that the attack detection rate is significantly improved after applying the SHAP feature selection technique.
