How should teams handle evidence mapping under NIST CSF 2.0?
Begin with a and a plain current-state statement describing how or to what extent its outcome is achieved. Link each artifact to that statement and record the system or process in scope, artifact owner, evidence period, covered population, reviewer, and known limitations.
An only indicates a relationship between a Core outcome and another standard, guideline, regulation, or document. NIST notes that one reference may address only part of a , so a crosswalk is neither proof of implementation nor proof that the full outcome is achieved.
is voluntary, outcome-based guidance and does not prescribe an audit evidence list, retention period, sample size, or assurance level. Those requirements may come from the mapped law, contract, regulator, assurance standard, or the organization's own method. Record that controlling source and do not attribute its legal force or deadline to NIST.
- Record the Profile boundary and exact Function, Category, and identifier.
- Describe what the artifact shows, the period and population it covers, and any exception or sampling limitation.
- Separate design evidence, such as an approved policy or configured rule, from operating evidence, such as logs, test results, tickets, or sampled records.
- Record management review or risk acceptance separately; approval of an exception does not show that the underlying outcome is achieved.
- Reassess the mapping when the scope, implementation, threat context, requirement, or evidence source changes.
