Selective Federated IDS Framework with Adaptation for Large-scale Segmented Industrial Networks
This paper introduces SAFID, a novel federated intrusion detection framework designed for large-scale, segmented industrial networks utilizing Time-Sensitive Networking (TSN). SAFID addresses the challenges of data heterogeneity, resource constraints, and real-time requirements by intelligently classifying domains into active (data-rich) and passive (data-scarce) participants. It leverages federated learning for active domains to train a compact neural network (TDNet) and implements lightweight adaptation for passive domains, ensuring robust threat detection and operational stability.
