Accountability should sit with the business owner for purpose and necessity, and with the technical steward for operational control. That split reduces ambiguity during offboarding, rotation, and recertification, and it gives security teams a clear path for remediation when an identity becomes risky.
Why This Matters for Security Teams
Accountability is the difference between a governable NHI estate and a pile of unowned credentials. When business ownership is unclear, teams miss purpose, retention, and recertification decisions; when technical stewardship is unclear, rotation, vaulting, logging, and revocation drift. That gap shows up fastest in offboarding and exceptions. nhi governance works best when it is treated as a lifecycle control, not a one-time provisioning task, as reflected in NHI Lifecycle Management Guide and Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs. NIST CSF 2.0 also reinforces that ownership, monitoring, and remediation need clear operational assignment, not shared ambiguity, especially around asset and access governance (NIST Cybersecurity Framework 2.0). In practice, many security teams encounter orphaned service identities only after access sprawl or a failed incident response has already exposed the gap.
How It Works in Practice
The practical model is a split-responsibility pattern. The business owner defines why the NHI exists, what system or workload it supports, and whether it still has a legitimate purpose. The technical steward owns how it is implemented and controlled: issuance, storage, secret rotation, monitoring, and removal. That division avoids the common failure mode where security assumes application teams are reviewing usage, while application teams assume security is handling revocation. Guidance from OWASP Non-Human Identity Top 10 and Top 10 NHI Issues both point to lifecycle control gaps as a core source of exposure.
In a mature operating model, accountability should be explicit in policy and tickets, not implied in org charts. A workable structure usually includes:
- Business owner approves creation, validates necessity, and signs off on periodic recertification.
- Technical steward enforces JIT credential provisioning, short TTLs, and automated rotation.
- Security defines minimum controls, reviews exceptions, and escalates stale or high-risk identities.
- Platform or IAM teams implement vaulting, logging, and revocation workflows.
That alignment matters because NHI risk is often invisible until something breaks. For example, Entro Security reports that 91% of former employee tokens remain active after offboarding in its 2025 State of NHIs and Secrets in Cybersecurity, which is a strong signal that ownership gaps are operational, not theoretical. Current guidance suggests using lifecycle checkpoints tied to onboarding, change, renewal, and decommissioning, rather than relying on ad hoc review cycles. These controls tend to break down in highly automated CI/CD environments because identities are created faster than ownership records are updated.
Common Variations and Edge Cases
Tighter governance often increases administrative overhead, so organisations have to balance control quality against delivery speed. That tradeoff is real, especially for engineering teams with many ephemeral workloads or shared platforms. Best practice is evolving, but there is no universal standard yet for exactly how ownership should be divided when a single NHI serves multiple applications or when platform teams provision identities on behalf of product teams. In those cases, a named business owner still needs to exist, but the technical steward may sit in a central platform or SRE function.
Exceptions also arise with third-party integrations, vendor-managed services, and OAuth-connected tools. In those environments, accountability should include the internal owner of the risk, even if the credential is issued or maintained externally. That is especially important when visibility is poor and usage patterns are opaque. The issue is not just who can change the secret, but who can answer whether the identity should still exist. NHIMG recommends pairing accountability with documented lifecycle evidence, using resources such as Guide to NHI Rotation Challenges and Guide to the Secret Sprawl Challenge to pressure-test recertification and inventory discipline. Where identities are shared across teams or services, accountability breaks down unless one party is clearly empowered to approve continued use and one party is clearly on the hook for technical enforcement.
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-03 | Lifecycle rotation and revocation are central to accountable NHI stewardship. |
| NIST CSF 2.0 | PR.AC-4 | Accountability depends on clear access governance and least-privilege enforcement. |
| NIST AI RMF | AI RMF GOVERN supports assigning responsibility for autonomous or semi-autonomous identities. |
Assign an owner for rotation, revocation, and recertification, then automate checks against NHI-03.
