# How should teams handle threat modeling under NIST SP 800-218 SSDF?

How should teams handle threat modeling under NIST SP 800-218 SSDF? Clear, source-linked guidance with practical evidence checks, owner decisions, and implementation steps.

*FAQ* *GLOBAL* *NIST SP 800-218 SSDF*

## NIST SP 800-218 SSDF How should teams handle threat modeling under NIST SP 800-218 SSDF

A standalone answer for teams deciding how threat modeling should be scoped, evidenced, assigned, and reviewed under NIST SP 800-218 SSDF.

Grounded in NIST SSDF guidance, this answer provides practical criteria, owner roles, evidence expectations, and review gates for threat modeling.

Short answer: treat threat modeling as an SSDF design activity, not a one-time checklist item. NIST SP 800-218 says to use forms of risk modeling - such as threat modeling, attack modeling, or attack surface mapping - to assess software risk, then track the security requirements, risks, and design decisions so the model can be reviewed and updated as the software, threat space, or environment changes.

## Use threat modeling to assess software risk

NIST SP 800-218 says to use forms of risk modeling - such as threat modeling, attack modeling, or attack surface mapping - to help assess the security risk for the software.

In practice, that means building the threat model early enough to inform design decisions, then keeping the model current as the software changes. The SSDF also says to track the software's security requirements, risks, and design decisions, including approved exceptions, so the team can justify choices and revisit them later.

- Use threat modeling early in design so the results can shape security requirements and controls.
- Update the model when architecture, dependencies, releases, or operating conditions change.
- Record the risks, design decisions, and approved exceptions so the team can explain why the design was accepted.
- Use the model to decide whether mitigations, alternate designs, or additional checks are needed.

Sources for this answer:

- [NIST SP 800-218 SSDF v1.1](https://doi.org/10.6028/NIST.SP.800-218?ref=sorena.io) - SSDF practice PW.1.1 explicitly calls for risk modeling such as threat modeling, and PW.1.2 calls for tracking security requirements, risks, and design decisions.

## What evidence should support threat modeling under NIST SP 800-218 SSDF?

Use threat modeling evidence to show how the team identifies design risks, documents mitigations, assigns ownership, and reviews the model when architecture, dependencies, suppliers, or release scope changes.

- Write the decision and scope in one sentence.
- Attach the source-linked evidence that proves the current state.
- Name the accountable owner and backup reviewer.
- Record unresolved gaps, accepted risk, and dependencies.
- Set a date or event trigger for reassessment.
