Protection Of Critical Infrastructure

The strategic prioritisation of critical infrastructure protection and national resilience has consolidated as a central organising principle across NATO [1] , the European Union [2] and allied national security architectures because contemporary deterrence and defence now depend materially on the continuity of complex civilian networks and services under conditions of coercion, hybrid activity and high-intensity conflict. [3] This shift is visible in the formal elevation of resilience and civil preparedness within NATO’s strategic texts and summit outcomes, where resilience is framed simultaneously as a national responsibility and a collective commitment, explicitly linked to credible deterrence and defence.

[4] It is equally visible in the EU’s framing of security and defence as dependent on a broader security union and preparedness architecture, in which essential services and infrastructure resilience become security-relevant instruments rather than only regulatory or economic concerns. The structural threat environment that elevated this priority is characterised by the interaction of conventional military risk with deliberate activity below the threshold of open armed attack and by systemic shock hazards.

NATO’s 2022 Strategic Concept explicitly embeds the challenge of coercive political and economic tactics, hybrid methods, cyber threats, and the strategic significance of resilience within an integrated security environment shaped by state competition and persistent instability. [6] The post-February 2022 security context, defined by Russia [7] ’s full-scale war against Ukraine [8] and the broader return of high-intensity war planning in Europe, has accelerated the recognition that the Alliance’s force posture, reinforcement plans, and industrial mobilisation are only credible if civilian infrastructure can absorb disruption while continuing to enable military movement, sustainment, command and public order.
