Lifecycle State & Audit

Lifecycle-state evidence helps a recipient decide whether an asset is active, accepted, deployed, repaired, transferred, revoked, retired, or decommissioned. Audit evidence helps show whether controls operated for a specific product, event, supplier, or lifecycle stage.

Decision Supported​

What is the current lifecycle state of the asset, and what evidence shows that lifecycle decisions were made and executed correctly?

Who Produces It​

Asset management systems, manufacturers, operators, service providers, repairers, transfer agents, identity systems, decommissioning workflows, auditors, and assessors may produce lifecycle-state and audit evidence.

Who Consumes It​

Operators, buyers, auditors, assessors, incident responders, product-security teams, procurement teams, and downstream service providers may consume it.

When It Is Generated​

Evidence may be generated during acceptance, deployment, update, repair, transfer, revocation, audit, incident response, and decommissioning.

When It Is Verified​

Verification may occur during audit, renewal, repair return-to-service, ownership transfer, incident investigation, or decommissioning review.

Evidence Examples​

  • Asset lifecycle-state records.
  • Acceptance records.
  • Deployment records.
  • Repair records.
  • Re-provisioning evidence.
  • Transfer and ownership records.
  • Revocation logs.
  • Decommissioning records.
  • Audit logs.
  • Verifier logs.
  • Control assessment records.

What Makes It Verifiable​

Lifecycle-state and audit evidence is stronger when events are timestamped, attributable, integrity-protected, tied to a product or asset identity, and connected to the evidence that justified the lifecycle decision.

Retention​

Retention depends on asset life, support life, contractual obligations, audit needs, incident response, and decommissioning requirements. Some records may need to survive ownership transfer or retirement.

Practical Questions​

Questions to ask suppliers​

  • What artifact, record, measurement, certificate, manifest, log, or report can you provide for this evidence area?
  • When is it generated, updated, superseded, or retired?
  • What product, component, version, supplier scope, or lifecycle event is it bound to?

Questions to ask internally​

  • What decision will this evidence support: selection, acceptance, operation, update, audit, transfer, or retirement?
  • Who verifies it, what acceptance criteria apply, and what happens if the evidence is missing or inconsistent?
  • How long does it need to remain available and interpretable?

Questions to ask assessors / auditors​

  • Can origin, integrity, freshness, scope, and product binding be checked independently?
  • Is there a clear trail from the evidence to the control, requirement, or assurance claim being assessed?
  • Are gaps, exceptions, expired artifacts, or remediation actions recorded?

Questions to ask implementers​

  • What system or process produces this evidence with enough metadata for later verification?
  • How are signatures, hashes, timestamps, issuers, trust anchors, and access controls protected?
  • How will recipients retrieve, verify, refresh, and correlate the evidence across lifecycle events?

Standards And Technology Support​

Relevant mappings may include asset management systems, audit evidence stores, signed logs, revocation mechanisms, certificate lifecycle records, RATS verifier logs, and governance frameworks.

What It Does Not Solve​

Lifecycle-state records do not prove technical integrity unless connected to integrity evidence. Audit records do not prove security by themselves unless they connect controls, evidence, verification, and decisions.
