This comparison helps teams mapping NIST SSDF to SLSA. The goal is not to pick a winner; it is to separate scope, owners, evidence, review cadence, and assurance so one implementation record can support both sides without overclaiming. ## NIST SSDF vs SLSA: practical side-by-side comparison Compare NIST SSDF and SLSA with side-by-side scope, owner, trigger, evidence, cadence, assurance, and decision-rule rows. - **NIST SSDF**: NIST SSDF is the primary scoping column: use it to confirm covered facts, accountable owners, mandatory artifacts, timing, and enforcement exposure before assigning implementation work. - **SLSA**: SLSA is the second workstream in this comparison. Use it to test where the comparator has different scope, owners, triggers, evidence, timing, enforcement, and reuse limits from NIST SSDF. | Dimension | NIST SSDF | SLSA | Operational implication | Sources | | --- | --- | --- | --- | --- | | Scope and covered activity | SSDF defines the secure software development practices to apply across the SDLC. Use NIST SSDF to show which product, release, supplier, or process is in scope before you map any evidence. | SLSA defines supply-chain integrity levels and provenance for build and release artifacts. Use SLSA when the question is whether the build or artifact chain can be trusted and verified before deployment. | For scope, write separate acceptance criteria for NIST SSDF and SLSA; reuse evidence only where it proves both claims without changing the meaning. | [NIST SP 800-218 SSDF v1.1](https://doi.org/10.6028/NIST.SP.800-218?ref=sorena.io) - Primary NIST source for comparing SSDF secure-development practices with SLSA software supply-chain provenance and artifact integrity expectations.

Use NIST SSDF first when you need a control-and-practice checklist for how software is developed, reviewed, or fixed, and you need named owners for those tasks. - Use SLSA first when you need a build or artifact trust claim, such as proof that the delivered software came from a controlled build and can be verified before release. - Use both when the same release must satisfy both development-practice evidence and provenance evidence.

Read the table row by row and write a decision record for the actual scope. The useful output is a source-linked mapping, not a broad statement that the two frameworks are similar. - Define which side is the primary driver. - Identify shared evidence only after both source-linked claims are clear. - Keep legal, certification, customer, and internal governance timers separate.
