Abstrakt:

In this article, we propose a lightweight, hierarchical multi-task learning framework designed for detecting both high-level and fine-grained threats in IoT traffic. The developed model focuses on anomalies detectable through flow-level metadata. The deliberate choice to prioritize computational efficiency by excluding content analysis scopes the approach to payload-independent threats, while still enabling robust detection of key attack classes. To further enhance efficiency within this metadata-driven paradigm, we introduce HC-MTDNN, a hierarchical multitask model that integrates a gated feature mechanism and feature reuse to significantly reduce redundancy and computational overhead, improving upon previous hierarchical architectures and achieving high performance while dealing with volumetric and protocol-based attacks. The model is evaluated on four benchmark datasets: CICIoT2023, N-BaIoT, Bot-IoT, and Edge-IIoTset. It demonstrates strong performance in both binary and multiclass classification tasks, with an average inference time of 122 us per sample and a compact model size of 2.4 MB. The proposed framework effectively balances accuracy and computational efficiency, offering a practical and scalable solution for securing resource-constrained IoT environments.
