This research introduces GeMID, a two-stage framework for building generalizable IoT device identification models that are robust across diverse network environments. The framework demonstrates that packet-header-based features, rigorously selected through cross-dataset validation, yield superior generalizability compared to widely used flow- or window-based statistical features.
Key insights
- Cross-validation within a single dataset often overestimates feature utility; multi-dataset, cross-environment validation is essential for selecting features that generalize.
- Features derived from individual packet headers (e.g., `dstport_class`, `ip.len`, `ip.ttl`) provide significantly better generalizability for IoT device identification than flow- or window-based statistical features.
- A systematic, multi-stage feature selection process that explicitly targets robustness across diverse network conditions leads to more reliable and adaptable DI models.
