The AutoBoost-IoT Framework
The core innovation lies in combining unsupervised deep learning (Deep AutoEncoder) for advanced feature extraction with a robust ensemble classifier (XGBoost). This synergy ensures both effective dimensionality reduction for complex IoT traffic and highly accurate, multi-class attack classification.
AutoEncoders transform high-dimensional network data into concise latent representations, reducing noise and highlighting critical patterns. XGBoost then leverages these refined features for superior classification, capable of handling class imbalances and learning complex decision boundaries.
Unprecedented Detection Accuracy
Evaluated on the N-BaIoT and CICIoT2023 benchmark datasets, the AutoBoost-IoT model demonstrated superior accuracy compared to traditional methods. With 99.63% accuracy on N-BaIoT and 98.94% on CICIoT2023, the system proves highly effective in distinguishing between benign traffic and various sophisticated attack types, including Mirai and Gafgyt botnet variants.
The model consistently achieves high precision, recall, and F1-scores across multiple attack categories, validating its robustness and generalization capabilities in dynamic IoT environments.
Efficient Deployment for IoT Edge
A key advantage of AutoBoost-IoT is its computational efficiency, making it suitable for resource-constrained IoT edge environments. The autoencoder-based feature extraction reduces data dimensionality, leading to a smaller model size and significantly lower inference latency (0.189 ms/sample for XGBoost).
This design prioritizes real-time threat detection without requiring high computational overhead, enabling rapid responses to intrusions and mitigating alert fatigue in operational settings.
