OT coalition urges ISA/IEC 62443 as unified ICS standard
The Operational Technology Cybersecurity Coalition released a July 23 position paper urging federal policymakers to adopt ISA/IEC 62443 as a single horizontal standard for industrial control system security. Operators currently navigate overlapping mandates (the paper cites TSA pipeline security directives and NERC Critical Infrastructure Protection standards as examples) with no shared technical baseline across sectors. Coalition executive director Tatyana Bolton told Inside Cybersecurity that CIRCIA's proposed harmonization exception, which lets entities skip duplicate reporting under a "substantially similar" framework, can't function cleanly for OT until regulators agree on a common standard to measure similarity against.
