Ownership should sit with the identity or security team that governs lifecycle and access policy, not only with the application team consuming the secret. When ownership is unclear, rotation and offboarding become optional behaviour. The better model is a shared control plane with clear accountability for placement, rotation, and cross-account access.
Why This Matters for Security Teams
Non-human secrets are not just another application setting. They are the access layer that lets scripts, pipelines, services, and agents reach production systems, so unclear ownership quickly becomes a governance failure. When the application team controls the workload but no one owns the secret lifecycle, rotation slips, stale access persists, and offboarding is missed. That is exactly the pattern highlighted across NHIMG research on the Guide to the Secret Sprawl Challenge and the State of Secrets in AppSec.
The control model matters because secrets fail in predictable ways: they are copied into code, shared across teams, left behind in CI/CD, or rotated manually until the process breaks down. OWASP’s Non-Human Identity Top 10 treats this as an identity governance problem, not just a vaulting problem. In practice, many security teams encounter secret sprawl only after a leaked credential is already being reused across environments.
How It Works in Practice
The strongest operating model is a shared control plane with clear separation between ownership of the workload and ownership of the secret lifecycle. The identity or security team should define policy, approve privileged access patterns, set rotation standards, and govern cross-account or cross-environment access. The application or platform team should own the consumer side: where the secret is injected, how the workload uses it, and what breaks if it is revoked.
That split prevents the common failure mode where every service team manages secrets differently. A practical model usually includes:
- Central policy for issuance, rotation, revocation, and emergency kill switch actions
- Per-workload accountability for secret usage, storage location, and environment scope
- Just-in-time issuance where possible, especially for pipelines and ephemeral jobs
- Continuous inventory of secret consumers, including service accounts, agents, and automation
- Audit trails that show who approved access, who rotated it, and who still depends on it
That approach aligns with current guidance from the 52 NHI Breaches Analysis, which shows how quickly non-human access becomes an incident when no single owner is accountable. For implementation detail, the OWASP Non-Human Identity Top 10 is useful for mapping secret governance to identity risks rather than treating secrets as a separate bucket. These controls tend to break down in highly federated organisations where each engineering group runs its own vaulting process because enforcement becomes inconsistent and rotation exceptions accumulate.
Common Variations and Edge Cases
Tighter central control often increases operational overhead, requiring organisations to balance governance consistency against delivery speed. That tradeoff is real, especially in teams that rely on many short-lived services, partner integrations, or regulated production environments. Best practice is evolving, but there is no universal standard for when the security team should fully own the secret versus co-own it with the platform team.
In practice, the right answer depends on how the secret is used. Long-lived API keys, database passwords, and cross-account access credentials usually need stronger central ownership because they create broader blast radius. Secrets embedded in CI/CD or automation deserve even more scrutiny because they are frequently copied, cached, or logged. For transient workloads, current guidance suggests moving toward ephemeral credentials and workload identity so the question shifts from “who stores the secret” to “who authorises the workload at runtime.” That is where the Ultimate Guide to NHIs — Static vs Dynamic Secrets becomes especially relevant.
Where this guidance gets weakest is in legacy systems that cannot use short-lived credentials, because static secrets then become a controlled exception rather than a preferred design.
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 CSA MAESTRO 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-03 | Secret ownership is central to rotation and lifecycle control. |
| NIST CSF 2.0 | PR.AC-1 | Access control ownership defines who can issue and govern secrets. |
| NIST Zero Trust (SP 800-207) | PR.AC | Zero trust supports runtime access decisions for non-human workloads. |
| NIST AI RMF | AI risk governance applies when agents consume non-human secrets. | |
| CSA MAESTRO | MAESTRO addresses governance for autonomous workloads using secrets. |
Assign a named owner for each non-human secret and enforce rotation, revocation, and review on schedule.
