On Thursday, April 9th, 2020, I gave a presentation to INCOSE Critical Infrastructure Protection and Recovery(CIPR) working group monthly call. With the large attendance, it was evident there was an interesting learning about the critical, but generally not addressed, issues of the engineering aspects of control system cyber security. There was also a common thread that control system cyber security issues are more than just IT/OT convergence. From the broad participation in the call, it was also evident there is a need for these different standards and engineering organizations to collaborate and the need for coordination among these groups. To date, it is unclear who will step up to do the coordination.
