OB-IDS: Optimized BERT-based Intrusion Detection System

"OB-IDS (Optimized BERT-based Intrusion Detection System)" presents a lightweight IDS optimized for the resource-constrained environments. The proposed system which employs quantization, pruning, knowledge distillation and self distillation methods is developed in a multi-stage optimization manner. It was evaluated on UNSW-NB15 and CIC-IDS2017 datasets. The proposed system was found to significantly reduce the inference time and memory usage while maintaining high classification accuracy. The experimental results demonstrate the applicability of Transformer-based IDSs for real-time threat detection in resource-constrained environments.
