A state where an artifact is correctly signed or attested, but the identity behind the build or release process is no longer trustworthy. The artefact may verify cleanly while the release pipeline itself has already been compromised, which means provenance checks must be paired with identity governance.
Expanded Definition
Provenance without trust describes a condition where an artefact, such as a container image, signed package, build output, or model artifact, still validates cryptographically while the identity that produced it can no longer be relied on. The signature or attestation may be intact, but the release path may already have been abused through stolen credentials, a compromised CI/CD runner, or a hijacked maintainer account. In NHI security, this matters because provenance answers “where did this come from,” while identity governance answers “who had authority to make it.” The two controls must be evaluated together, not as substitutes.
Definitions vary across vendors, but the operational meaning is consistent: a trusted-looking artefact can still be unsafe if the NHI behind the build or release process has lost integrity. That is why provenance checks should be paired with secrets hygiene, workload identity controls, and release-approval policy. Standards and guidance around secure software supply chains, including the NIST Cybersecurity Framework 2.0, support this layered view rather than treating signatures as a final guarantee.
The most common misapplication is treating a valid signature as proof of safety when the signing identity, build runner, or release authority has already been compromised.
Examples and Use Cases
Implementing provenance controls rigorously often introduces release friction, requiring organisations to weigh faster delivery against the cost of stronger identity assurance and attestation review.
- A signed container image passes verification, but the CI service account used to publish it was exfiltrated the day before release.
- A software bill of materials exists, yet the build pipeline used a compromised ephemeral token that allowed an attacker to inject code into the artifact.
- An internal model artifact carries valid attestation, but the automation account that approved promotion into production was granted excessive privileges.
- A package repository shows correct provenance metadata, while the maintainer’s NHI was hijacked through leaked API keys stored outside a secrets manager.
These scenarios are common in modern supply chains because artefact integrity and identity integrity fail in different places. The Ultimate Guide to NHIs notes that 96% of organisations store secrets outside of secrets managers in vulnerable locations, and 80% of identity breaches involved compromised non-human identities such as service accounts and API keys. That combination makes a valid artefact insufficient evidence on its own. Supply chain guidance from NIST Cybersecurity Framework 2.0 is most useful when provenance is treated as one layer inside a broader trust decision.
Why It Matters in NHI Security
Provenance without trust is a governance failure because it creates a false sense of assurance. Teams may assume a verified build is safe, while the real weakness sits in the NHI that signed, promoted, or deployed it. That gap is especially dangerous in agentic and automated environments, where service accounts, workload identities, and CI/CD credentials can act with broad authority at machine speed. If those identities are not rotated, scoped, and monitored, a trustworthy-looking artifact can become an attack vehicle.
For NHI practitioners, the key lesson is that provenance controls do not replace identity lifecycle controls. They must be tied to least privilege, secret rotation, approval segregation, and release-time monitoring. The Ultimate Guide to NHIs shows that only 20% of organisations have formal processes for offboarding and revoking API keys, which helps explain why compromised release identities can persist long enough to poison otherwise signed artefacts. Organisational leaders typically encounter this problem only after a cleanly verified release is traced back to a breached pipeline, at which point provenance without trust becomes operationally unavoidable to address.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 and OWASP Agentic AI Top 10 address the attack and risk surface, while NIST CSF 2.0, NIST Zero Trust (SP 800-207) and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-02 | Covers improper secret and NHI lifecycle management that can undermine trusted provenance. |
| OWASP Agentic AI Top 10 | A-03 | Agentic release automation can be abused even when artefacts remain cryptographically valid. |
| NIST CSF 2.0 | PR.AC-4 | Least privilege and access control are necessary to keep build and release provenance trustworthy. |
| NIST Zero Trust (SP 800-207) | SA-3 | Zero Trust requires continuous validation of identities and sessions, not trust in a signed artifact alone. |
| NIST AI RMF | AI risk management includes provenance, traceability, and governance of the identities behind model artifacts. |
Verify the signing and release NHIs are governed, rotated, and revocable before trusting any attestation.
