The Purdue Model has had a long run as THE ICS ARCHITECTURE. Although there have been tweaks, such as DMZ’s represented as Level 2.5 and 3.5, it has been mostly unchanged for almost three decades. With the advent of IIoT / Industrie 4.0, cloud services, AI, sensors everywhere and other technical innovations, is it time to kill off the Purdue Model? And if so, is there A MODEL that can replace it? Or are we looking at a set of principles rather than a model? And if so what are those principles?
Lots of questions, and the Brad, Joel and Dale will explore and argue about these questions and possible answers.
