Use the same discipline you would apply to privileged access. Limit publish and signing rights to named roles, require ownership, and make offboarding immediate when a maintainer, service account, or automation path is no longer needed. The goal is to stop trusted channels from becoming unaudited propagation paths.
Who should be allowed to publish or sign software artifacts?
Publishing and signing rights should be treated as privileged supply-chain authority, not as a convenience permission. Limit them to named roles with clear ownership, separate human and automation duties where possible, and require immediate removal when a maintainer, service account, or build path is no longer legitimate. If the channel can propagate trusted software, it needs tight control and fast revocation.
What makes publish and signing rights different from ordinary access?
These rights can change what other teams install, deploy, or trust. A compromised publisher or signer can turn one account into many downstream installations, so the access decision is really about blast radius, provenance, and accountability. That is why teams should prefer explicit role assignment over informal “whoever maintains the repo” practices.
Named ownership matters because it gives you a decision point for review, rotation, and offboarding. If nobody can explain why an identity can publish or sign, the control is already too loose. The right test is whether the role is necessary to move a validated artifact through release, not whether the person or automation is merely capable of doing it.
How should teams define the approval boundary?
Use a narrow approval boundary around artifact creation, release, and signing. The people who build code do not automatically need the power to publish it, and the systems that package code do not automatically need the power to sign it. When the same identity can both produce and vouch for an artifact, the review bar should be higher because compromise becomes harder to detect.
For signing specifically, teams should decide whether the signer is a human-owned key, a dedicated automation identity, or a protected service. Each option changes the governance burden: human keys depend on strong custody and offboarding, while automation and service identities depend on secret handling, runtime limits, and rotation discipline. SLSA is useful here because it frames signing and provenance as part of a defensible software supply chain, not just a release-step preference.
Risk and Threat Considerations
Publish and signing privileges are attractive to attackers because they sit on a trusted path. If an adversary takes over a maintainer account, build token, or signing key, they may be able to inject malicious artifacts that appear legitimate to downstream consumers. The same risk appears when an old automation path is left active after the original purpose has ended.
Failure mechanism: Excessive or stale publish rights let an unauthorized identity reach the release channel, while long-lived signing authority can survive role changes, team turnover, or environment drift.
Impact: A single compromise can propagate trust at scale, leading to silent distribution of altered software, difficult attribution, and costly emergency revocation or rebuilds.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
SLSA, NIST SP 800-53 Rev 5, CIS Controls v8 and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| SLSA | Supply-chain Levels for Software Artifacts | Artifact signing and publishing are supply-chain trust controls. |
| Recommendation — Adopt SLSA provenance expectations for artifact publication and signing trust. | ||
| NIST SP 800-53 Rev 5 | AC-6 — Least Privilege | Publishing and signing should be limited to the minimum authority required. |
| IA-5 — Authenticator Management | Signing keys, tokens, and publish credentials need lifecycle control and revocation. | |
| Recommendation — Restrict artifact publish and sign rights to the minimum necessary set of roles. Manage, rotate, and revoke signing and publish credentials promptly. | ||
| CIS Controls v8 | CIS-5 — Account Management | Named roles and immediate offboarding are account-governance decisions. |
| Recommendation — Inventory, approve, and remove artifact-publishing accounts and keys promptly. | ||
| NIST CSF 2.0 | PR.AA-05 — Manage Access Credentials and Accounts | Publishing and signing rights depend on credential and account governance. |
| Recommendation — Control artifact-publishing credentials and accounts through explicit ownership and revocation. | ||
Practitioner Guidance
What to verify: Confirm that every publish or signing right maps to a current business owner, a named operational role, and a documented reason for existence. If an identity cannot be tied to a release responsibility, remove or replace it before the next release cycle.
Common mistake: Teams often secure the build system but leave publishing and signing paths broad, shared, or inherited. That creates a hidden trust layer where legacy access can outlive the project, the person, or the pipeline that created it.
Practitioner takeaway: The safest model is not “who can technically do it,” but “who still needs to be trusted to vouch for software today,” with immediate offboarding for anything that no longer meets that test.
