NIST SP 800-53 Rev 5HIPAA Security Rule

NIST SP 800-53 Rev 5 covers 77.6% of HIPAA Security Rule

52 of the 67 controls in HIPAA Security Rule are already satisfied by evidence you collected for NIST SP 800-53 Rev 5. 15 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.

claims rejected in review

This number is directional. It says how much of HIPAA Security Rule your NIST SP 800-53 Rev 5 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.

207 candidate mappings were examined and 123 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.

NIST800-PM-1164.308(a)(1)(i)argued against and upheld

Security Management Process (Standard)

PM-1 requires a documented security program to prevent, detect and correct violations.

NIST800-RA-3164.308(a)(1)(ii)(A)argued against and upheld

Risk Analysis (Required)

RA-3 requires assessing risk to confidentiality, integrity and availability of information.

NIST800-RA-7164.308(a)(1)(ii)(B)argued against and upheld

Risk Management (Required)

RA-7 requires responding to assessed risk and reducing it to an acceptable level.

NIST800-PS-8164.308(a)(1)(ii)(C)argued against and upheld

Sanction Policy (Required)

PS-8 requires a formal sanctions process for personnel who fail to comply.

NIST800-AU-6164.308(a)(1)(ii)(D)argued against and upheld

Information System Activity Review (Required)

AU-6 requires regular review and analysis of audit records and access reports.

NIST800-PM-2164.308(a)(2)argued against and upheld

Assigned Security Responsibility (Standard)

PM-2 requires appointing a senior official accountable for the security program.

NIST800-AC-2164.308(a)(3)(ii)(A)argued against and upheld

Authorization and Supervision (Addressable)

AC-2 requires authorization and approval for accounts and supervision of their use.

NIST800-PS-3164.308(a)(3)(ii)(B)argued against and upheld

Workforce Clearance Procedure (Addressable)

PS-3 personnel screening is the clearance determination before granting access.

Claims that did not hold

121 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.
