K06 assurance and procurement architecture

NIST operational-technology security Official-Source Review

Direct answer

SP 800-82 Revision 3 remains the final OT security publication at the K07 cutoff.

Authority and evidence boundary. K06 publishes reference architecture, source review, machine-checkable dependencies, procurement scope, and test-evidence formats. These records do not certify a facility, award a contract, authorize an operation, prove deployment, establish current operation, or transfer regulatory or command authority.

Supported bounded propositions

  • SP 800-82 Revision 3 remains the final OT security publication at the K07 cutoff.
  • NIST initiated a Revision 4 pre-draft process in January 2026.

Unavailable or unresolved

  • The Revision 4 pre-draft notice is not a final control baseline.
  • NIST guidance does not decide NRC, NERC, contract, or facility applicability by itself.
