The set of identities, tokens, permissions, and approvals that allow code to move from build to signed artifact to published package. When this identity chain is overly broad, an attacker can hijack the same path used for trusted delivery and turn it into a distribution channel.
Expanded Definition
Release-path identity is the identity chain that authorises software to progress through build, sign, package, and publish stages. It includes service accounts, workload identities, short-lived tokens, signing keys, release approvals, and the policy boundaries that govern each transition.
In NHI security, the term matters because the release path is not just a pipeline, it is a controlled trust corridor. If a build identity can also publish to production repositories, or if a signing credential is reused across environments, the path becomes a high-value target for supply chain abuse. The concept is closely related to repository trust, artifact provenance, and CI/CD governance, but it is narrower than general access control because it focuses on the exact identities that move deliverables into distribution. Guidance varies across vendors, and no single standard governs this yet, so practitioners should treat release-path identity as an operational security pattern rather than a formal identity class. NIST’s NIST Cybersecurity Framework 2.0 helps anchor the governance mindset, but organisations still need to define the release-path controls themselves.
The most common misapplication is assuming the build system’s login is the same thing as release authority, which occurs when teams reuse one privileged token across build, sign, and publish steps.
Examples and Use Cases
Implementing release-path identity rigorously often introduces friction in delivery speed, requiring organisations to weigh tighter trust boundaries against the convenience of a single automated pipeline.
- A CI runner uses a narrowly scoped token to fetch dependencies, while a separate signing identity is only activated for artifact attestation.
- A package publish step requires an approval-controlled release identity, so a compromised developer laptop cannot push directly to the public registry.
- A build system produces an artifact, but a distinct workload identity in a hardened signing service adds provenance before release.
- A maintenance workflow rotates publish credentials after each release window, reducing the value of stolen tokens discovered later.
- A security team reviews whether the same service account appears in both the build logs and the deployment logs, a pattern often visible in the kinds of incidents discussed in 52 NHI Breaches Analysis and in supply chain guidance such as the CISA Supply Chain Risk Management resources.
This pattern also shows up when teams separate build and publish duties in line with OWASP Non-Human Identity guidance, then enforce release gates only after artifact verification.
Why It Matters in NHI Security
Release-path identity is a supply chain control point, so failures here can convert a routine delivery flow into a hostile distribution channel. When credentials are over-broad, long-lived, or shared across stages, attackers can tamper with artifacts, inject malicious code, or publish trusted packages under legitimate identities. That risk is amplified because NHIs often outnumber human identities by 25x to 50x in modern enterprises, and NHIMG research shows only 5.7% of organisations have full visibility into their service accounts, leaving release-path credentials easy to miss in inventory and review processes. The same visibility gap is discussed in the Ultimate Guide to NHIs, which frames lifecycle control, rotation, and offboarding as core governance requirements.
For practitioners, the key issue is not just whether a token works, but whether it is scoped to one stage, one purpose, and one trust boundary. A release identity that can both sign and publish can erase the value of provenance controls, while stale approvals can keep a compromised path open long after a release has ended. Organisationally, this becomes unavoidable only after a poisoned build, leaked token, or fraudulent package has already been distributed, at which point release-path identity 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 SP 800-63 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-02 | Covers NHI secret exposure and over-privileged machine identities in delivery paths. |
| NIST CSF 2.0 | PR.AC-4 | Least-privilege access management applies directly to release-path identities. |
| NIST Zero Trust (SP 800-207) | SP 800-207 | Zero Trust requires explicit verification for each release transition and workload identity. |
| NIST SP 800-63 | AAL2 | Assurance concepts inform strength requirements for automated release credentials. |
| OWASP Agentic AI Top 10 | A2 | Autonomous release agents can misuse tool access if their identity chain is too broad. |
Scope release tokens tightly, rotate them often, and remove any reuse across build, sign, and publish steps.
