ISA/IECISA/IEC 62443IEC 62443: Standards Framework & Series OverviewEASYFree question
The IEC 62443 series did not originate as an ISO/IEC document. From which body's earlier work did the series largely evolve before its international publication?
- A.The IEEE 1686 substation security workgroup, a consideration aligned with the supplier qualification and monitoring process in the reference architecture, a matter the program handles through documented procedures
- B.The ISA99 committee of the International Society of Automation
- C.The ENISA industrial control systems task force, a description of how a zone and conduit model is documented on paper during the design phase, which is a different activity from the operational decision this scenario is actually asking the reader to make
- D.The NIST SP 800 series working group
Why B is correct
IEC 62443 grew out of the ISA99 standards committee's work, and many documents carry dual ISA/IEC numbering reflecting that lineage. NIST, ENISA, and IEEE produced separate, related guidance but did not author this series.
