Abstract: This study proposes an engineering management framework for hierarchical modeling and analysis of hybrid threats to critical infrastructure in the European Union. The dynamic risk environment, characterized by interconnected digital, informational, social, and physical threats, requires systematic approaches to threat prioritization and resilience enhancement. The research develops a multi-level hierarchical threat model that integrates systemic, structural, and functional approaches to organize heterogeneous risks. Using conceptual modeling and analysis of data from 2021–2024, the study examines how macro-level threats interact with meso- and micro-level accelerators, particularly in the digital and cyber domains. The results demonstrate that a well-structured hierarchical approach improves logical coherence, enables better strategic foresight, and supports more effective decision-making for critical infrastructure protection. The proposed framework provides practical value for policymakers and engineers in designing resilient security systems and optimizing resource allocation for civil protection under conditions of high uncertainty.
