How do you build an SSDF evidence binder in 30 days with a small team?

A small team can assemble a useful SSDF evidence binder in four weeks by working one practice group per week: prepare, protect, produce, respond. For each practice, save one policy, one artifact that shows it in use and one owner. Stop at what you can truthfully show.

Before you start

Pick one product or one company-wide scope. NIST notes that many PO practices also apply to subsets of development such as a group or project, so a single product is a valid starting scope. Create a folder with four subfolders named after the practice groups.

Week 1: Prepare (PO)

1. Write short security requirements for your tooling, software and suppliers (PO.1).
2. List roles and who holds them (PO.2.1).
3. Record leadership sign-off (PO.2.3).
4. Export settings that show gates and environment separation (PO.4, PO.5).

Week 2: Protect (PS)

1. Screenshot or export repository access rules (PS.1).
2. Show how releases are signed or checksummed (PS.2).
3. Save the release archive location and the SBOM from the last release (PS.3).

Week 3: Produce (PW)

1. Pick one recent design review or threat model (PW.1, PW.2).
2. Save a code review sample showing required approval (PW.7).
3. Save a test run and a dependency scan from CI (PW.4.4, PW.8).
4. Note build settings that improve executable security (PW.6).

Week 4: Respond (RV)

1. Publish or update the disclosure policy (RV.1.3).
2. Save three triage tickets with decisions (RV.2).
3. Write one root cause note from a past bug (RV.3).
4. Write an index linking every practice to its artifact.

The index matters most

A spreadsheet with columns for practice, what you do, evidence link, owner and last review date is more useful than a thick folder. Use the attestation evidence index approach for the layout.

The stop rule

If you cannot find evidence for a practice, write that down as a gap with an owner and a date. Do not backfill with invented documents or describe a practice as done when it is not. A short honest gap list builds more trust with a buyer than a spotless binder that falls apart under questions.

Keep it alive

After week four, schedule a monthly check of the index and an annual review of the policies. Set a rule that any pipeline change that affects evidence updates the index.

Who does what

Assign one lead for each week, ideally the person closest to the topic: a platform engineer for protect, a tech lead for produce and whoever handles incidents for respond. Give each lead two hours of meeting time with a compliance or operations partner at the start of the week, to agree which artifacts to save. Keep the total effort modest. The goal of a first pass is a truthful baseline you can improve, not a perfect archive.

Try it yourself

Click through it at your own pace, or open it full screen. Look at how one piece of evidence can be tied to several practices at once.
