“…Researchers have proposed means to reduce misclassifications involving threat context computation [4] and intrusion root cause analysis [8]. However, such works employ ontological techniques [7] that are computation-heavy [1] and provide no information on the decentralization of policies, affecting the real-time performance of HetIoT-NIDPS especially during big data processing.…”

“…The dynamic contexts in a HetIoT adversely affect the context unaware low-level statistical inferences of ID algorithms. Thus, reinforcing them with the extracted high-level behavioral descriptions improves network redesign that is context-aware and resistant to frequent security compromises, benefitting from the interpretability of knowledge-driven specification and the adaptability of data-driven detection [1]. To achieve this, we propose an EK framework.…”

“…Learning-based network intrusion detection systems (NIDS) for such HetIoT infrastructures suffer from high misclassification rates [1], [8] due to context-unaware statistical evaluation of (machine or deep) learning-based algorithms as HetIoT involves dynamic contexts. Such dynamic scenarios necessitate reinforcing an expert knowledge (EK) framework for context-aware decision-making and minimizing false alerts [2], [4], [6], [7] to avoid high recovery costs due to failure.…”
