Acronyms: CSI, CII, CI --- Phannarith - I must admit we haven't even thought of this when writing this introduction :) 'Societal' emerged rather as a way to explain better what we might mean by 'critical infrastructure'.

Bennette's suggestion makes sense: CII is about information infrastructure - thus telecommunications, digital service providers, maybe cloud operators, etc (though this will also be an interesting issue for discussion, latter in module 5).

CI, as critical infrastructure, is much broader - includes energy, water and sewage, health, maybe finances, etc - and also CII these days.

CSI - as critical societal infrastructure - is not really a common term (at least I haven't seen it much in the context of cyber), but what we meant by this here is rather same as CI.

Does it make sense?
