Distribution of records. (a) Edge-IIoTset dataset is highly imbalanced with several attack categories have relatively few samples, reflecting the realistic scenario where certain exploits are less frequent, (b) CIC-IoT2023 dataset contains several high-volume attack categories and all 33 specific attacks fall into these 7 classes; the figure aggregates at class-level for clarity, and (c) TII-SSRC-23 dataset grouped attacks into four high-level categories and contains many sub-types under each category (26 malicious sub-types total).
