Doing some pondering, digging and backtracking on the issue of IoTA. But, … already got stuck when considering how to (best?) model the architecture at lower levels. Would a classical picture, or a somewhat-less classical picture work best to gain understanding of the risk areas ..? As in:
Industrial control cycle

Where the former is from the industrial, process-oriented engineering world, and the latter from the digital networking world.

Yes I’d really like your advice on how to ‘marry’ both to be able to optimally visualise where the risks are; the potential, intentional or not, noise on the signal, or the wrong signals altogether. What might cause that, how to protect against that, etc.
Yes, taking into account the work already done here – which is impressive, but somewhat (?) protocols-oriented, not architecture-/risk-oriented. Yet. Something like
[plucked off a simple search] is what I’m after.

But the other work, too. All, to overlay with risk lists on all surfaces at all levels… Then, to see how to protect that all against the (generic?) risks, and how one would audit sufficient (?) protection is in place. Not ‘controls’ – those are the losers’ weak retreats, the “didn’t want a cookie anyway” fig leaves. Taking into account this breakthrough though.
But for now, again already, leaving you with:
