What are the key differences between NIST SP 800-66 and ISO 27799?

NIST SP 800-66 has 24 controls across its framework, while ISO 27799 covers 24 controls. Direct mapping analysis identifies 10 overlapping controls (42% coverage). The frameworks diverge most significantly in NIST SP 800-66: Organizational Requirements, where 4 NIST SP 800-66 controls have no direct ISO 27799 equivalent.

How many controls map between NIST SP 800-66 and ISO 27799?

Of 24 total NIST SP 800-66 controls, 10 map directly to ISO 27799 controls — representing 42% coverage. The remaining 14 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.

What are the compliance gaps when mapping NIST SP 800-66 to ISO 27799?

14 NIST SP 800-66 controls have no direct equivalent in ISO 27799. The highest concentration of gaps is in NIST SP 800-66: Organizational Requirements with 4 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 NIST SP 800-66 and ISO 27799?

The domain with the highest gap count is NIST SP 800-66: Organizational Requirements (4 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
