NIST releases first ICS/OT incident response guide
The manufacturing sector gets its own cyber playbook for the first time.
TL;DR
NIST NCCoE released the initial public draft of SP 1800-41 on Wednesday. It is the first NIST special publication to treat ICS/OT incident response as a discipline separate from IT. Developed with 11 industry collaborators, the draft provides reference architectures and recovery scenarios for manufacturing environments. Comments close July 8, 2026. Manufacturing firms and supply-chain partners should review now: if adopted as a contractual reference by DoD or DHS, OT-specific IR capabilities shift from best practice to requirement.
The draft was developed with 11 industry collaborators and includes reference architectures, response and recovery scenarios, and capability demonstrations for manufacturing environments. The key structural choice is the separation of OT from IT. Previous NIST incident response guidance folded industrial controls into broader IT frameworks. SP 1800-41 addresses the operational realities of factory floors: safety interlocks, physical processes, proprietary protocols, and recovery timelines measured in production hours rather than service-level agreements. For defense contractors and critical-infrastructure suppliers running ICS, the draft is worth tracking even at this stage. If the final version is adopted as a contractual reference point by DoD or DHS customers, manufacturers will need to demonstrate OT-specific response and recovery capabilities aligned with SP 1800-41's reference architecture. The open question is whether NIST will recommend specific recovery time objectives for OT restoration. A measurable RTO would turn the guidance into a compliance benchmark rather than a best-practices document.
