What are the key differences between IEC 62443 and NIST SP 800-144?

IEC 62443 has 81 controls across its framework, while NIST SP 800-144 covers 8 controls. Direct mapping analysis identifies 10 overlapping controls (12% coverage). The frameworks diverge most significantly in 62443-3-3 System Security Requirements, where 24 IEC 62443 controls have no direct NIST SP 800-144 equivalent.

How many controls map between IEC 62443 and NIST SP 800-144?

Of 81 total IEC 62443 controls, 10 map directly to NIST SP 800-144 controls — representing 12% coverage. The remaining 71 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.

What are the compliance gaps when mapping IEC 62443 to NIST SP 800-144?

71 IEC 62443 controls have no direct equivalent in NIST SP 800-144. The highest concentration of gaps is in 62443-3-3 System Security Requirements with 24 unmapped controls. These gaps represent areas where additional controls, policies, or documentation must be created to achieve compliance with both frameworks.

Which control domains have the most gaps between IEC 62443 and NIST SP 800-144?

The domain with the highest gap count is 62443-3-3 System Security Requirements (24 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
