Open DGML: Intrusion Detection Based on Open-Domain Generation Meta-Learning

Network security is crucial for national infrastructure, but the increasing number of network intrusions poses significant challenges. To address this issue, we propose Open DGML, a framework based on open-domain generalization meta-learning for intrusion detection. Our approach incorporates flow imaging, data augmentation, and open-domain generalization meta-learning algorithms. Experimental results on the ISCX2012, NDSec-1, CICIDS2017, and CICIDS2018 datasets demonstrate the effectiveness of Open DGML. Compared to state-of-the-art models (HAST-IDS, CLAIRE, FC-Net), Open DGML achieves higher accuracy and detection rates. In closed-domain settings, it achieves an average accuracy of 96.52% and a detection rate of 97.04%. In open-domain settings, it achieves an average accuracy of 68.73% and a detection rate of 61.49%. These results highlight the superior performance of Open DGML, particularly in open-domain scenarios, for effective identification of various network attacks.
