Is The Purdue Model Dead (E)
Unsolicited Response Podcast
info_outlineThere are many articles on digital twins that describe what they are and how they can help with predictive maintenance, efficiency studies, and other tasks of increasing interest and value. On the security side digital twins provide the data and infrastructure to perform process variable anomaly detection ... the holy grail of ICS cyber incident detection. We saw a prime example of this at S4x19 with GE's Digital Ghost.
So information on the what and why of digital twins is readily available. What I've never understood is exactly how digital twins are build. So I tracked down someone who does this for a variety of different systems, Mike Aylott of KBC, a Yokogawa company.
Mike educates me on how digital twins come from, and differ from, simulation software. He provides some ballpark numbers, talks about what makes a digital twin easier (cheaper) or harder (more expensive) to create. When a digital twin is finished and a lot more. Mike even steps up to the challenging question of what percentage of deployed ICS will have a digital twin in the near future.
