Treat build and release credentials as privileged machine identities with limited scope, short lifetimes, and strict ownership. If those identities can sign, deploy, or fetch dependencies broadly, a code flaw can become a platform-wide incident. Identity controls should be part of every vulnerability remediation discussion.
Why This Matters for Security Teams
Build and release identities sit between source code, artifact repositories, CI/CD runners, package registries, and production deployment paths. That makes them high-value machine identities, not ordinary service accounts. When their permissions are too broad, a single compromised pipeline can sign malicious releases, overwrite artifacts, or push code into trusted environments without human interaction.
Security teams often focus on source code review and ignore the identities that move code into production. That gap matters because appsec failures increasingly involve credential abuse, dependency tampering, and pipeline takeover rather than only code defects. The NIST Cybersecurity Framework 2.0 is useful here because it pushes organisations to treat identity, access, and resilience as operational controls rather than one-time setup tasks.
The practical question is not whether a pipeline is automated. It is whether every build and release action is tightly bound to a named workload, a clear purpose, and an audit trail that can survive incident response. In practice, many security teams discover build identity overreach only after an attacker has already used the release path to distribute trusted malware.
How It Works in Practice
Governance starts by defining each build and release identity as a distinct Non-Human Identity with a documented owner, purpose, scope, and expiry model. That includes CI runners, signing services, artifact publishers, deployment bots, and any token used to pull dependencies or access secrets. Best practice is to avoid shared credentials and to issue short-lived credentials where possible, especially for ephemeral build agents.
Operationally, teams should map each identity to the minimum set of actions it needs. A build job may need read access to a specific repository, write access to a narrow artifact bucket, and permission to request a signing operation, but not broad admin rights across environments. Release identities should be even tighter, because they represent the last step before production. Where feasible, use OIDC federation or workload identity rather than static secrets, and store signing keys in controlled systems with strong separation of duties.
Effective governance also depends on evidence and review:
- Inventory all pipeline identities, secret stores, and signing paths.
- Assign an accountable owner for each identity and rotate or revoke unused ones.
- Log authentication, signing, deployment, and dependency access events.
- Check whether a release identity can be reused outside its intended pipeline.
- Validate that remediation workflows include identity changes, not only code fixes.
Security teams should also align this work with supply chain guidance. The NIST Secure Software Development Framework is helpful for connecting build governance to secure development practices, while MITRE ATT&CK can help teams model abuse paths such as valid accounts, credential theft, and lateral movement from build systems into production. These controls tend to break down when multiple repositories share the same release token because blast radius becomes impossible to contain.
Common Variations and Edge Cases
Tighter build identity control often increases operational overhead, requiring organisations to balance release speed against auditability and separation of duties. That tradeoff is real, especially in teams that ship continuously and rely on highly ephemeral infrastructure.
There is no universal standard for every pipeline pattern yet. Some organisations can enforce per-service identities with strong federation, while others still depend on long-lived tokens because of legacy tooling or limited platform support. Current guidance suggests that static secrets should be treated as a transitional risk, not a preferred design.
Edge cases matter. For example, a release identity that only signs artifacts may still be critical if downstream systems trust that signature blindly. Similarly, a build identity that only reads dependencies can still become a pivot point if the dependency source is compromised. Teams should also be cautious with self-hosted runners, shared build pools, and cross-environment promotion flows, because these environments often blur ownership and make revocation slower. Where OWASP SAMM is used, identity governance should be embedded into maturity checks for build integrity, not left as a separate infrastructure task. In hybrid estates, the hardest failures usually appear when one pipeline spans development, security, and operations boundaries with inconsistent policy enforcement.

OWASP Non-Human Identity Top 10 and MITRE ATT&CK 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.
