HIPAA Security RuleNIST SP 800-53 Rev 5

HIPAA Security Rule covers 12.7% of NIST SP 800-53 Rev 5

38 of the 300 controls in NIST SP 800-53 Rev 5 are already satisfied by evidence you collected for HIPAA Security Rule. 262 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 HIPAA Security Rule 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.

187 candidate mappings were examined and 129 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.

164.312(a)(2)(iii)NIST800-AC-11argued against and upheld
Device lock

Terminating a session after a predetermined time of inactivity is device lock.

164.312(a)(2)(iii)NIST800-AC-12argued against and upheld
Session control

Automatic logoff after inactivity is session termination.

164.308(a)(4)(ii)(C)NIST800-AC-2argued against and upheld
Account management

Documenting, reviewing and modifying a user's right of access is account management.

164.308(a)(4)(ii)(B)NIST800-AC-2argued against and upheld
Account management

Granting access via workstation, transaction, program or process is account authorization.

164.312(a)(1)NIST800-AC-3argued against and upheld
Access enforcement

Technical procedures allowing only authorized persons or programs access is access enforcement.

164.308(a)(5)(ii)(C)NIST800-AC-7argued against and upheld
Unsuccessful logon attempts

Monitoring log-in attempts and reporting discrepancies is the unsuccessful logon control.

164.308(a)(5)(ii)(A)NIST800-AT-2argued against and upheld
Literacy training and awareness

Periodic security updates and reminders are the ongoing awareness this control requires.

164.308(a)(5)(i)NIST800-AT-2argued against and upheld
Literacy training and awareness

A security awareness and training program for all workforce members is literacy training.

Claims that did not hold

128 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.
