What evidence do auditors commonly ask for on SR-9(1) Tamper Resistance and Detection | Multiple Stages of System Development Life Cycle?

Supply chain risk management policy and procedures; Supply chain risk management plan; System and services acquisition policy; Procedures addressing tamper resistance and detection; Tamper protection program documentation; Tamper protection tools and techniques documentation.

What is the most common gap auditors find on SR-9(1)?

Anti-tamper techniques are applied at delivery only, not across design, development and maintenance stages

NIST SP 800-53 Rev 5 · SR - Supply Chain Risk Management

`SR-9(1)` Tamper Resistance and Detection | Multiple Stages of System Development Life Cycle

Employ anti-tamper technologies, tools, and techniques throughout the system development life cycle.

Source: NIST SP 800-53 Rev 5, SR-9(1). The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open NIST SP 800-53 Rev 5 in the compliance library.

Base controls and their enhancements. Which apply follows the baseline you are assessed against (for example FedRAMP Moderate or High, or the low, moderate and high baselines of SP 800-53B). Text in square brackets is a parameter your organisation sets.

where the evidence lives

teal = a system already holds it · olive = produced at each review. To go live: easy when half or more of the artefacts are already held by a system, moderate from a quarter to a half, hard below a quarter.

These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

First move

No system holds this evidence for you: it is people and documents. Reminders and routing to the owner still save time. Put the document under version control with an owner and review date, and log each review as a record with reviewer and date.
