A timeline of cyber-resilience: fortifying critical national infrastructure

By Peter Lenk, Tech Lead at Goldilock


Critical national infrastructure (CNI) faces a mounting threat landscape, necessitating a fundamental overhaul of security strategies.


Consider last summer’s attack on London hospitals, where just one cyber incident resulted in the postponement of 1,255 planned operations and 3,396 appointments. Incidents like this are unfortunately no longer exceptional. Following the attack, the National Cyber Security Centre (NCSC) warned that the “scale, pace, and complexity” of threats to CNI is rising. Meanwhile, the UK science secretary called Britain “desperately exposed” to cyber threats, raising the alarm that national resilience is in jeopardy.


From transport networks to utility providers, pipelines, port facilities, and healthcare systems, CNI is integral to the smooth running of countries. That makes it an alluring target for criminals who can ignite rippling chaos from just one successful cyber incident.


Traditional security isn’t enough for CNI

With cyber threats to CNI on the rise, experts around the world are increasingly calling for legislation “that will mandate cyber resilience measures for CNI systems,” as seen by the Directive (EU) 2022/2555 of the European Parliament and of the Council of 14 December 2022 on measures for a high common level of cybersecurity, as well as the Strengthening American Cybersecurity Act of 2022, which addresses cybersecurity threats against US critical infrastructure and the federal government.


New legislation is a welcome step forward, but if CNI organisations wish to protect themselves from ..
