AWS Well-Architected Security Pillar covers 20.9% of NIST SP 800-161 Rev 1

40 of the 191 controls in NIST SP 800-161 Rev 1 are already satisfied by evidence you collected for AWS Well-Architected Security Pillar. 151 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.

What this leaves you to do

NIST SP 800-161 Rev 1 has 191 controls. Holding AWS Well-Architected Security Pillar already evidences 40 of them, so the work in front of you is 151 controls, not 191, which is 79% of the standard rather than all of it.

That is the whole claim. Every number in that sentence comes from the two counts above it and can be re-derived from the free tools without taking our word for any of it.

In money, using only our numbers. The full report is $299 and names 40 controls of NIST SP 800-161 Rev 1 you do not have to implement again, which is $7.47 per control identified. That arithmetic uses our price and our count and assumes nothing about you.

In your hours, using your assumption. We do not know what a control costs you to implement, so pick the column that looks like your organisation. These are your figures, not our claim.

Multiply by your own rate. We publish no rate because we have not measured yours, and a number built on an invented rate is the kind of claim this platform exists to argue against.

This number is directional. It says how much of NIST SP 800-161 Rev 1 your AWS Well-Architected Security Pillar 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.

95 candidate mappings were examined and 0 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.

SEC 3: How do you manage permissions for people and machines? | SEC03-BP09AC-17argued against and upheld
Remote Access

Third party access is granted through assumed roles rather than long-lived users.

SEC 3: How do you manage permissions for people and machines? | SEC03-BP06AC-2argued against and upheld
Account Management

Joiner mover leaver driven grant and revocation brings external accounts into the lifecycle.

SEC 3: How do you manage permissions for people and machines? | SEC03-BP09AC-20argued against and upheld
Use of External Systems

Contractual controls plus scoped roles set the terms for third party processing.

SEC 3: How do you manage permissions for people and machines? | SEC03-BP07AC-22argued against and upheld
Publicly Accessible Content

Detects resources granting public access and validates each against documented intent.

SEC 2: How do you manage identities for people and machines? | SEC02-BP06AC-24argued against and upheld
Access Control Decisions

Attribute based access control bases decisions on defined attributes, not relationship.

SEC 3: How do you manage permissions for people and machines? | SEC03-BP02AC-3argued against and upheld
Access Enforcement

Policies grant only specific actions, resources and conditions, enforcing the boundary.

SEC 3: How do you manage permissions for people and machines? | SEC03-BP09AC-6argued against and upheld
Least Privilege

Third party roles use external ID, condition keys and time bound credentials.

SEC 3: How do you manage permissions for people and machines? | SEC03-BP02AC-6argued against and upheld
Least Privilege

Least privilege policies grant only the actions the engagement actually requires.

Claims that did not hold

Nothing proposed for this pair was rejected in review. That is unusual and worth knowing rather than hiding: it means the candidate set was small and every candidate held.
