Accountability should sit with the credential owner, the system owner, and the governance function that approved its lifecycle. If those roles are unclear, token risk will persist because no one is responsible for revocation, review, or behavioural monitoring. Clear ownership is the difference between a controllable credential and an orphaned one.
Why This Matters for Security Teams
When a non-human credential exposes cloud resources, the failure is rarely just technical. It is usually an accountability gap across identity, platform, and governance teams. Non-human identities do not behave like employees, so the usual assumption that one owner, one manager, and one review cycle will catch problems is weak. That is why guidance from the OWASP Non-Human Identity Top 10 matters: orphaned secrets, overbroad scopes, and weak lifecycle ownership are recurring patterns, not edge cases.
NHIMG’s research shows the issue is widespread. In the 2024 Non-Human Identity Security Report, 88.5% of organisations said their non-human IAM practices lagged behind or were only on par with human IAM, which helps explain why cloud exposure often persists after the first incident. If ownership is unclear, revocation stalls, review never happens, and monitoring becomes nobody’s job. In practice, many security teams encounter exposure only after a secret has already been reused, copied, or embedded into automation.
How It Works in Practice
Accountability should be assigned across three layers: the credential owner, the system owner, and the governance function that approved the credential’s lifecycle. The credential owner is responsible for how the secret is issued, rotated, stored, and revoked. The system owner is responsible for the workload, pipeline, or cloud service that uses it. The governance function sets minimum standards for approval, review, and exception handling.
For cloud environments, that means treating secrets as operational assets, not static admin conveniences. Current guidance suggests using short-lived credentials where possible, enforcing purpose-bound access, and requiring a named approver for every high-risk secret. The Ultimate Guide to NHIs — Static vs Dynamic Secrets is useful here because it frames the practical difference between long-lived secrets that drift into exposure and dynamic secrets that can be revoked quickly. For broader incident patterns, the 52 NHI Breaches Analysis shows how often weak secret governance becomes a breach amplifier.
- Tag each non-human credential to a business service, repository, or workload owner.
- Record who can approve issuance, who can revoke it, and who reviews its continued need.
- Set review intervals based on risk, not convenience, and tie them to evidence of active use.
- Alert on unusual token use, cross-environment access, and failed revocation attempts.
For identity proofing and lifecycle rigor, the NIST SP 800-63 Digital Identity Guidelines remain a useful reference point, even though non-human identities require additional workload-specific controls. These controls tend to break down when credentials are shared across teams without a single revoke authority because no one has enough context or permission to act fast.
Common Variations and Edge Cases
Tighter ownership often increases operational overhead, requiring organisations to balance faster delivery against stronger control. That tradeoff becomes sharper in platform engineering, CI/CD, and AI-driven automation, where one credential may support many jobs, environments, or services. There is no universal standard for this yet, so current guidance suggests documenting the owner at the workload level and the approver at the lifecycle level, even if the same person fills both roles in smaller teams.
Edge cases appear when secrets are embedded in third-party integrations, ephemeral build runners, or outsourced managed services. In those settings, the system owner may not control the runtime, but they still own the risk acceptance decision. The governance function should require evidence of rotation, scoped permissions, and offboarding controls before exceptions are approved. The Guide to the Secret Sprawl Challenge is especially relevant when organisations discover they have more active secrets than they can inventory or review reliably.
For AI-enabled automation, the accountability model needs an extra check: if an agent can request or consume the credential autonomously, ownership must include behavioural monitoring and a revocation path that works without human delay. That concern is reinforced by the emerging risk picture in the Anthropic report on AI-orchestrated cyber espionage. In practice, cloud exposure becomes hardest to assign when credentials cross organisational boundaries, because each party assumes another team owns the final risk decision.
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 address the attack and risk surface, while NIST CSF 2.0 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-01 | Directly addresses orphaned and poorly owned non-human credentials. |
| NIST CSF 2.0 | PR.AC-1 | Access management must define who can approve and revoke credentials. |
| NIST AI RMF | GOVERN | Governance is needed to assign responsibility for autonomous credential use. |
Assign a named owner for every NHI credential and require documented revoke authority.
