Enhancing IoT Intrusion Detection Systems through Adversarial Training

The augmentation of Internet of Things (IoT) devices transformed both automation and connectivity but revealed major security vulnerabilities in networks. We address these challenges by designing a robust intrusion detection system (IDS) to detect complex attacks by learning patterns from the NF-ToN-IoT v2 dataset. Intrusion detection has a realistic testbed through the dataset's rich and high-dimensional features. We combine distributed preprocessing to manage the dataset size with Fast Gradient Sign Method (FGSM) adversarial attacks to mimic actual attack scenarios and XGBoost model adversarial training for improved system robustness. Our system achieves 95.3% accuracy on clean data and 94.5% accuracy on adversarial data to show its effectiveness against complex threats. Adversarial training demonstrates its potential to strengthen IDS against evolving cyber threats and sets the foundation for future studies. Real-time IoT environments represent a future deployment opportunity for these systems, while extensions to detect emerging threats and zero-day vulnerabilities would enhance their utility.
