Abstract

This study analyzes Ukraine’s cyber resilience as a practical example of collective defense within the context of hybrid warfare. Unlike earlier forms, contemporary hybrid warfare combines cyberattacks, information warfare, and conventional military assaults on governance systems, critical infrastructure, and public trust within a society. The targeted governance systems, critical infrastructure, and public trust within a society to undermine Ukraine’s national resilience. Ukraine’s response demonstrates how institutional reforms, technical redundancy, public–private partnerships, and societal engagement can strengthen national resilience against sustained multi-domain threats. The period of study in this paper focuses on the cyber operations on Ukraine from 2022 and the scope and effectiveness of the national cyber security systems, the international relations component, and the civil society and volunteer networks within Ukraine. The study concludes that Ukraine’s cyber strategy during this period facilitated the continuous provision of essential services, quick recovery, and diminished the strategic goals of the adversary in military operations. Ukraine’s experience also showed the challenges of asymmetry and dynamic evolution of threats. The study posits hybrid warfare, resilience, and collective defense. Ukraine’s cyber resilience exemplifies strategic cyber resilience in collective defense. The lessons from Ukraine to other states are in enhancing societal and institutional resilience to counter hybrid warfare as a primary building block of operational continuity.
