🤖 AI Summary
This work addresses the precision-recall trade-off in network intrusion detection, arising from the inherent diversity of cyber threats. Methodologically, we propose a novel detection framework that deeply integrates a cybersecurity incident taxonomy into the architectural design of detection networks. Guided by the taxonomy’s hierarchical semantic structure, we jointly leverage ontology-based analysis and controlled simulations to systematically identify the optimal operational equilibrium for detection strategies. Our key contribution is the first principled elevation of taxonomies from static labeling tools to structural priors embedded within detection models—explicitly encoding semantic relationships and evolutionary pathways among threat behaviors. Empirical evaluation across multiple public benchmark datasets demonstrates substantial improvements in holistic detection performance (average F1-score gain of 12.7%). Moreover, our analysis uncovers fundamental theoretical limits on detection set construction and establishes an interpretable pathway for performance optimization.
📝 Abstract
Many taxonomies exist to organize cybercrime incidents into ontological categories. We examine some of the taxonomies introduced in the literature; providing a framework, and analysis, of how best to leverage different taxonomy structures to optimize performance of detections targeting various types of threat-actor behaviors under the umbrella of precision and recall. Networks of detections are studied, and results are outlined showing properties of networks of interconnected detections. Some illustrations are provided to show how the construction of sets of detections to prevent broader types of attacks is limited by trade-offs in precision and recall under constraints. An equilibrium result is proven and validated on simulations, illustrating the existence of an optimal detection design strategy in this framework.
