SR-2 Supply chain risk management plan

The assessor looks for a single approved plan that names the systems, components or services it covers and walks through each life cycle phase the control lists, from research and development through disposal. The plan should state who approved it, the version in force, and how it is protected from unauthorized disclosure and modification. Keep version history in a wiki or document system that records the author, date and approver for every revision, so the assessor can see the plan changed in step with the environment. Confirm with your assessor which format and approval record they accept, since the control leaves those choices to the organization. XWiki keeps every page change under version control, recording what changed, when and by whom, and lets you compare versions and roll back, which fits this artifact well.

The review log is the record that proves the plan was reviewed at the frequency the organization defined, and that the review produced updates when needed. Each entry should carry a date, the reviewers, the approver, the outcome and a link to any resulting version. Assessors often find gaps here, where the plan says annual review but the log shows one entry from the first year. Set the review frequency in the plan itself, add a calendar trigger for it, and record reviews even when nothing changed. A review triggered by a material change, such as a new critical supplier or a major incident, should be logged separately with its reason. Keep the log in the same version-controlled space as the plan so the two cannot drift apart.

SP 800-53A lists examine objects for SR-2 that include a list of supply chain threats and a list of safeguards to be taken against those threats, so an assessor will ask to see both and check that the plan points to them. The threat list should reflect the organization's actual suppliers, components and delivery paths, with an owner and a date for each entry. The safeguards list should link each threat to the controls chosen to address it, such as the SR family controls or contract terms. Keep these lists as versioned documents referenced by the plan rather than embedded in it, so updates do not require reissuing the whole plan. Confirm the required level of detail with the assessor before building the lists.

The SR-2(1) enhancement requires an organization to establish a supply chain risk management team, so the assessor will look for a charter that names the team's members, roles, authority and reporting line, plus meeting records showing the team acted. Good evidence includes meeting agendas, minutes with decisions and action items, and records of reviews the team carried out on suppliers or the plan. The charter should state how the team connects to procurement, security and the owners of the systems in scope. Keep membership current by updating the charter when people change roles, and keep minutes in the same versioned space as the plan. Access to these records can be limited to team members through role-based permissions, for example in BookStack, which assigns abilities through roles and can override them per shelf, book, chapter or page.

The plan points to life cycle and acquisition documents, and assessors check that those documents exist, match the plan's scope, and are actually followed. Typical items include the system life cycle documentation, acquisition documentation, design and integration records, and maintenance and disposal procedures for the systems or components the plan covers. Assessors often sample a recent acquisition and trace it back to the plan. Keep these documents current by assigning an owner to each and tying updates to change requests. For component inventory evidence, OWASP Dependency-Track consumes and produces CycloneDX SBOMs and VEX, and identifies components with known vulnerabilities, outdated or modified components and license risk. Confirm with the vendor how its component records map to your asset inventory before relying on it as evidence.

The organization owns its controls and its evidence, so an internal owner, usually in security or risk management with procurement involved, should hold responsibility for each artifact. An implementation partner can help set up the document structure, version control, access roles and inventory integration, and can prepare evidence for an assessment. Only the independent assessor reports on whether SR-2 is satisfied. Between assessments, the owner should run a checklist covering plan approval, review log entries, threat and safeguard list updates, team meeting records and acquisition document currency. Ask any consultant to put that division of roles, and what they will and will not produce, in the written scope before work starts.

Ongoing cost is mostly staff time for reviews, team meetings and updating lists and documents, plus any tooling and support you buy. Costs rise with the number of suppliers, systems and components in scope, how often material changes happen, and how many approvers the plan requires. Tool licensing for open-source platforms is typically zero, but hosting, administration and integration are not, and these are paid to you or to a partner depending on who does the work. NIST does not estimate compliance costs, so ask any partner for a fixed-scope written quote that separates one-time setup (document structure, version control, role design, inventory integration) from recurring activity (reviews, evidence upkeep, support). Ask which items the quote assumes you will perform yourself.

The effort depends mostly on how many systems, components and services the plan must cover and how much of the life cycle already has documented owners. SR-2 asks for a plan covering research and development, design, manufacturing, acquisition, delivery, integration, operations, maintenance and disposal of the defined systems, components or services, so the scope decision comes first. Organizations with a clear system inventory and named acquisition owners usually spend less time than those assembling both from scratch. No duration is set by NIST, so ask your assessor or partner to show the work breakdown in the written scope, with each life cycle phase, its inputs and its reviewers listed before any drafting starts.

Yes, in most cases an internal team can write the plan, because SR-2 is a documentation and governance control rather than a technical build. The organization owns its controls and the plan, so the people who approve it must be inside the organization. The harder part is evidence: the plan has to be protected from unauthorized disclosure and modification, reviewed on a defined cycle, and traceable to how suppliers and systems are actually managed. An outside partner can help with the document structure, the scope mapping and the evidence trail, but an independent assessor is still needed to test the control against the assessment procedures in SP 800-53A.

The work needs three inputs from the organization: a current system and component inventory, a list of suppliers and the services they deliver, and named owners who can approve decisions. Time is also needed for reviews, because the plan must be reviewed on a defined frequency and updated when conditions change. Expect to supply acquisition documentation, life cycle documentation for each in-scope system, and the list of supply chain threats the organization already tracks. Gaps in these inputs usually become the largest source of delay, so confirm access and reviewer availability before the engagement starts.

SR-2 requires the plan to be reviewed and updated at a defined frequency, and the organization sets that frequency as an organization-defined parameter. NIST does not fix a number in the control text, so the organization chooses it and documents the choice. Reviews should also be triggered by significant changes, such as a new critical supplier, a major system change or a supply chain incident. Ask your assessor to confirm whether the chosen frequency matches any contract, FedRAMP or regulator requirement that applies to your environment.

Yes, an existing group can meet SR-2(1) if it is formally established as the supply chain risk management team and given the authority and skills the enhancement expects. SR-2(1) asks the organization to establish that team, so the key decision is designation and accountability rather than headcount. Procurement, security, legal and system owners often need to sit on the team together, because supply chain decisions cross those functions. Document the team's charter, its members and its decision rights, and confirm with your assessor that the existing group's remit covers the defined systems and components.

A quote should follow from a written scope, and it should list each deliverable, its owner and its acceptance criteria. Ask for the defined systems and life cycle phases in scope, the number of reviews included, the team and roles who do the work, and what the organization must supply. Separate one-time work, such as the first plan and the team charter, from recurring work, such as scheduled reviews and updates. DeployOpen does not publish a price list, and most engagements are fixed-scope, so the quote should state the scope it prices. Ask the independent assessor separately what testing and report fees apply, because only that assessor issues the assessment result.
