Informative video. Purdue model is purely for reference, then and now too, its not a one size fits all, thats something many forget while thinking about architecting ICS architectures. Also it mainly highlighted the need for securing the control system as in a minimum set of best practices. For todays requirements, we have to architect networks that is simple and meets our requirements. No point in having a very complex network which can have far reaching consequences. Also the debate on MPLS vs. SD-WAN will never end, to be honest, it depends upon the needs, data traffic and budget. Also vendor solutions for SD-WAN vary, but its a matter of time, everyone will start shifting to SD-WAN for various reasons.
Well.. after watching the video a couple of points: - Purdue is dead, vive Purdue! There is a slight move up in the abstract/concrete ladder but it is essentially the same thing; and it makes sense. - Second, this goes along the lines of software-defined-x changes/moves; here again it makes sense; - Third, last but not least and please don't excuse my French nor my chauvinism, this is where the French are best at: logic - you English people are best at process. Can't match. PS: no hard feelings, I can relate too as an Arab :D Seriously: thank you, it was very instructive...

Now this is a presentation to watch, :)
Agree re Purdue, its now modified to move the ownership of the new level 4/5 into the OT domain but with no IT assets in the new 4/5
First I like ... then I watch ... French 🇫🇷 oblige :D
