Enhanced security threats in wartime and post-crisis environments that require systemic resilience and the protection of national interests entail implementing national institutional, informational, legal, and human resources to their fullest capabilities. In so doing, it offers an unparalleled overview of the organizational, legal, informational, and human factors within public management that shape the performance of the national security system. This paper articulates and theorizes central principles for constructing a modern national security system featuring a hierarchy of national interests, multi-level state, sub-state, and non-state actor coordination, transparency, and attunement to global best practices. Utilizing NCSI as an empirical reference frame, the paper discusses the transformation of cybersecurity and digital preparedness capabilities among EU members for the period 2023-2025, displaying a longer-term view of increasing cyclicality of cyber resilience across the European security architecture. Strategic implications: the study suggests that the IIS's evolution must be based on a synergy of technological innovation, sound legal regulation, and competent human resources. The structure and processes of national security governance, therefore, need to be transformed into strategic decentralization, interinstitutional cooperation, and digital inclusion. The findings advance the theory and practice of the impact of digital transformation on national security governance mechanisms and provide conceptual premises for improving public management strategies in an age of globalization and technological convergence.
