Description
The ongoing armed conflict in Ukraine has served as an unprecedented stress test for
national cybersecurity frameworks, exposing both the capabilities and limitations of
existing cyber defence architectures under sustained adversarial pressure. This
paper examines two interrelated dimensions of cybersecurity governance that have
gained acute relevance in the context of European security: national-level cyber
incident prioritization and the adoption of zero trust architecture (ZTA) as a paradigm
shift in organizational security.
First, the paper presents a novel multi-factor methodology for cyber incident
prioritization developed for deployment within the CERT-UA operational environment.
This methodology integrates the Common Vulnerability Scoring System (CVSS) with
Ukraine’s national criticality levels through a hierarchical framework that incorporates
structured tie-breaking via multi-criteria decision analysis (MCDA). Simulation results
demonstrate its effectiveness in handling high-volume incident inflows while
maintaining decisive and transparent resource allocation — a critical capability for
states operating under persistent cyber threat.
Second, the paper analyses the zero trust concept as a forward-looking security
paradigm for European critical infrastructure. Drawing on a systematic review of
international ZTA models and practical deployment experiences across enterprises, it
identifies the principal barriers to implementation — including awareness gaps,
workforce shortages, and organizational complexity — and proposes actionable
recommendations for policymakers and security professionals.
By connecting operational-level incident response with strategic-level architectural
transformation, this paper contributes to an emerging interdisciplinary dialogue at the
intersection of cybersecurity engineering, security governance, and defence policy. It
offers empirically grounded insights relevant to European states seeking to
strengthen their cyber resilience amid an evolving threat landscape shaped by state-
sponsored cyber operations, digital infrastructure dependencies, and the imperative
for collective cyber defence within NATO and EU frameworks.
