White House Signs Critical Infrastructure Memorandum, Details Remain Unclear

George V. Hulme
Expert Don C. Weber writes that safety devices are within scope for cybersecurity risk assessments. This includes conducting high-level risk assessments to assemble documentation for specific Systems-under-Consideration (SuC) of the safety solution, performing a vulnerability assessment of the SuC, feeding the results into the detailed risk assessment to allow the risk management team to identify and address residual risks.
