NIST Cybersecurity Framework 2.0NIST SP 800-53 Rev 5

NIST Cybersecurity Framework 2.0 covers 32.7% of NIST SP 800-53 Rev 5

98 of the 300 controls in NIST SP 800-53 Rev 5 are already satisfied by evidence you collected for NIST Cybersecurity Framework 2.0. 202 are genuine gaps. Every claim below was judged against both control sets and then argued against; the ones that did not survive are published further down with the reason each failed.

This number is directional. It says how much of NIST SP 800-53 Rev 5 your NIST Cybersecurity Framework 2.0 evidence satisfies. The reverse pair is a different number, often very different, because a security standard has enormous depth for access control and almost none for lawful basis or data subject rights.

527 candidate mappings were examined and 308 were removed. Signed off 2026-08-19, review level machine verified. Mappings were judged by Claude Code rather than read line by line by a practitioner. Every claim shows its reasoning so you can check it. Ask and a practitioner will review this pair.

Where the gaps are

Coverage is never evenly spread. A source standard usually satisfies one part of a target almost completely and barely touches another, and which part is which is the thing worth knowing before you plan the work.

Theme level, not control level, deliberately. The per-control list of what is evidenced and what is a gap is the report itself, so publishing it here would be publishing the thing being sold.

Claims that held

A sample. Each one names the control whose evidence does the work, the control it satisfies, and why.

NIST-CSF-PR.IR-01NIST800-AC-17argued against and upheld
Remote access

Protecting networks and environments from unauthorized access is remote access control.

NIST-CSF-PR.IR-01NIST800-AC-18argued against and upheld
Wireless access

Protected network environments cover authorization and protection of wireless access.

NIST-CSF-PR.AA-01NIST800-AC-2argued against and upheld
Account management

Managing identities and credentials for users, services and hardware is account management.

NIST-CSF-PR.AA-05NIST800-AC-3argued against and upheld
Access enforcement

Access permissions and authorizations defined and managed is access enforcement.

NIST-CSF-PR.AA-05NIST800-AC-6argued against and upheld
Least privilege

Least privilege is explicit in the managed permissions and entitlements outcome.

NIST-CSF-PR.AT-01NIST800-AT-2argued against and upheld
Literacy training and awareness

Awareness and training for personnel to perform cybersecurity duties is literacy training.

NIST-CSF-PR.AT-02NIST800-AT-3argued against and upheld
Role-based training

Training for individuals in specialized roles is role-based training.

NIST-CSF-PR.PS-04NIST800-AU-12argued against and upheld
Audit record generation

Generating log records across system components is audit record generation.

Claims that did not hold

294 proposed mappings for this pair were rejected. They are kept in the graph rather than deleted, so what was thrown out is as inspectable as what survived. A crosswalk that never rejects anything is not being judged.
