NIST SP 800-171 Rev 3ASD Strategies to Mitigate Cyber Security Incidents

NIST SP 800-171 Rev 3 covers 70.3% of ASD Strategies to Mitigate Cyber Security Incidents

26 of the 37 controls in ASD Strategies to Mitigate Cyber Security Incidents are already satisfied by evidence you collected for NIST SP 800-171 Rev 3. 11 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

ASD Strategies to Mitigate Cyber Security Incidents has 37 controls. Holding NIST SP 800-171 Rev 3 already evidences 26 of them, so the work in front of you is 11 controls, not 37, which is 30% 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 26 controls of ASD Strategies to Mitigate Cyber Security Incidents you do not have to implement again, which is $11.50 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 ASD Strategies to Mitigate Cyber Security Incidents your NIST SP 800-171 Rev 3 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.

44 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.

Preventing Malicious Insiders1 of 1 evidenced
Preventing Malware Delivery and Execution14 of 17 evidenced, 3 to do
Limiting the Extent of Cyber Security Incidents7 of 10 evidenced, 3 to do
Detecting Cyber Security Incidents and Responding4 of 6 evidenced, 2 to do
Recovering Data and System Availability0 of 3 evidenced, 3 to do

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.

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.
