Re : critical services --- @Jorge: True. Health services and transports are totally critical, the COVID-19 pandemic has shown how both are too be taken very seriously as CI.

On another note, I find the French identification of critical sectors (opérateurs d'importance vitale) quite compelling. They clearly identify 12 sectors classified in 4 segments (Sovereign, Human, Economic and Technology). Health, Water and Food are in "Human". For example, Energy is in "Economic" with Finance and Transports.
