Applying ISO/IEC 27001/2 and the ISA/IEC 62443 Series for Operational Technology Environments

Many organizations have established policies and procedures governing the IT security in their office environment; many of these are based on ISO/IEC 27001/2. Some have attempted to address their operational technology (OT) infrastructure under the same management system, and have leveraged many IT/OT commonalities. The ISA/IEC 62443 series explicitly addresses issues such as these; this helps an organization to maintain conformance with ISO/IEC 27001 through common approaches wherever feasible, while highlighting differences in IT vs. OT approach where needed.

This white paper offers guidance for organizations familiar with ISO/IEC 27001 and interested in protecting the OT infrastructure of their operating facilities based on the ISA/IEC 62443 series. It describes the relationship between the ISA/IEC 62443 series and ISO/IEC 27001/2 and how both standards may be effectively used within one organization to protect both IT and OT.
