TL;DR: Most organisations cannot reliably tell which human owns a leaked secret or non-human identity, and that slows triage, breaks remediation, and complicates audits when accounts outlive their creators, according to Entro Security. Human accountability is now a core control plane for NHI governance, not an administrative detail.
At a glance
What this is: This is an analysis of why NHI ownership attribution matters, arguing that mapping secrets and non-human identities to accountable humans is now a core governance control.
Why it matters: It matters because IAM, PAM, and NHI programmes cannot remediate exposure quickly or prove accountability when the owner of a service account, API key, or secret is unknown.
Context
Ownership gaps are a governance problem, not just an incident-response inconvenience. When a secret, token, or service account is exposed, security teams need to know which human can approve rotation, coordinate with engineering, and confirm the risk is actually resolved.
NHI ownership attribution closes the gap between discovery and action. In practice, the control is about linking machine-executed access back to a human decision-maker across identity providers, ticketing systems, cloud policies, and code repositories.
The article frames this as a recurring enterprise issue during acquisitions, staff changes, and legacy workload sprawl. That is typical, not exceptional, in environments where non-human identities outnumber human users and ownership metadata is fragmented.
Key questions
Q: What breaks when a leaked secret has no clear owner?
A: Remediation slows because the team knows the secret is exposed but cannot quickly find the human who can rotate, revoke, or replace it without breaking production. That delay increases exposure time, complicates audit trails, and often leaves the issue unresolved until someone manually traces the workload history.
Q: Why does NHI ownership attribution matter for compliance and audit?
A: Compliance teams need evidence that exposed credentials were handled by accountable owners, not just detected by tooling. If ownership is unknown, the organisation cannot reliably prove who approved remediation, who accepted risk, or whether offboarding and role changes were reflected in the credential lifecycle.
Q: What problem does ownership attribution solve for service accounts and API keys?
A: It closes the gap between exposure detection and accountable remediation. Many organisations can find the secret, but not the human who introduced it, maintains it, or can safely replace it. Ownership attribution gives security teams a practical way to assign action without relying on informal knowledge that disappears during staff changes.
Q: When should security teams override automated NHI ownership mapping?
A: Override automation when the available signals are incomplete, stale, or clearly inconsistent with how the application is run. Legacy systems, shared pipelines, and ephemeral accounts often need manual review so the response lands with a real operator instead of an inferred but unreliable owner.
Technical breakdown
Why ownership metadata becomes the control plane for leaked secrets
A leaked secret is not only a credential problem. It is also a routing problem: remediation depends on finding the human with enough context and authority to rotate, revoke, or replace the credential without breaking the workload that depends on it. In many environments, ownership data is split across IdPs, ticketing systems, cloud IAM, and collaboration tools, so no single system can answer who owns the risk. That fragmentation creates delay, duplication, and false confidence. The result is a risk item that can be detected but not acted on with confidence.
Practical implication: treat ownership metadata as part of the credential lifecycle, not as an optional enrichment field.
How hierarchy-aware attribution works across service accounts and API keys
Attribution models work by correlating signals from code, chat, cloud IAM, and identity systems, then assigning a primary human owner and fallback escalation paths. That matters because the person who introduced a secret is not always the person who can safely remove it. A repository admin, project lead, or organisation owner may be the correct escalation target when the original author is unavailable or has changed roles. This is less about blame than about operational reach. The key technical idea is contextual ownership, where remediation authority follows the actual organisational structure around the secret or workload.
Practical implication: define primary and fallback owners for every NHI class that can outlive the original creator.
Why manual override still matters in NHI attribution workflows
Automated mapping will never cover every case. Legacy apps, shared pipelines, and ephemeral accounts often lack enough telemetry to infer a reliable owner, especially when historical activity is sparse or organisational records are incomplete. In those situations, manual reassignment is not a workaround but a control requirement. It allows security teams to move from uncertain attribution to an accountable operator who can complete remediation. Without that override path, the workflow stalls at detection and the organisation keeps treating unresolved ownership as an acceptable ambiguity.
Practical implication: build a governed manual override path for ambiguous ownership cases and review those exceptions as control failures.
Breaches seen in the wild
- Dropbox Sign breach 2024: A compromised back-end service account gave attackers Dropbox Sign customer data, including API keys, OAuth tokens and MFA information.
- Hugging Face Spaces breach 2024: Unauthorised access to Hugging Face Spaces may have exposed secrets users stored for AI apps; tokens were revoked and org tokens removed.

NHI Mgmt Group analysis
NHI ownership is the missing accountability layer in many identity programmes. Security teams often have detection, ticketing, and cloud controls, but no dependable way to connect an exposed secret to the human who can safely act. That gap turns remediation into a search problem instead of a governance process. The implication is that ownership attribution has become part of the identity control plane, not an administrative afterthought.
Ownership attribution is about authority, not blame. The useful question is rarely who created the secret, but who can remove, rotate, or replace it without breaking business operations. That distinction matters in acquisitions, role changes, and shared delivery pipelines where the original creator may no longer be the right responder. Practitioners should design for accountable action, not retrospective fault-finding.
Context-aware escalation is what makes attribution operational. A primary owner alone is often insufficient when a workload survives the person who introduced it. Escalation to repo admins, project leads, or organisation owners reflects how real remediation actually happens across teams and systems. The practitioner takeaway is to map ownership as a hierarchy, not a single name in a field.
Manual override exposes the limits of automation and the maturity of governance. Some NHIs will never have clean provenance, especially in legacy estates and shared pipelines. In those cases, the unresolved ownership state is itself the risk signal, because it means no reliable human can be held to account for remediation. Mature programmes treat those exceptions as governance debt, not as acceptable noise.
From our research library:
- 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, according to the Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.

What this signals
Identity ownership debt: Many exposure events remain open longer than necessary because the remediation path is unclear, and that makes ownership metadata part of the control surface rather than a reporting convenience. Teams that cannot route a leaked secret to the right human should treat the gap as a standing governance defect.
NHI ownership attribution also changes how security programmes handle org churn. Mergers, layoffs, and role changes are exactly when dormant service accounts and forgotten secrets become hardest to govern, because the operational context that once explained them has already moved on.
For practitioners
- Map every exposed NHI to a human owner Require service accounts, API keys, tokens, and certificates to carry a current human owner and a fallback escalation owner before they reach production.
- Correlate ownership data across the stack Join identity provider records, cloud IAM policy data, code repositories, ticketing systems, and collaboration tools so attribution is based on evidence, not guesswork.
- Build exception handling for ambiguous ownership Create a manual reassignment path for legacy apps, shared pipelines, and orphaned secrets, then review those cases as governance exceptions rather than routine alerts.
- Route remediation through the actual responder Push ownership metadata into Slack, SOAR, and ticketing workflows so the person who can rotate or revoke access receives the assignment immediately.
Key takeaways
- Leaked secrets and non-human identities create a response problem when no human owner can be identified quickly enough to act.
- Ownership attribution ties remediation to accountable people, which shortens triage and improves auditability across complex identity estates.
- Programmes that cannot assign or override ownership for orphaned NHIs are carrying unresolved governance debt, not just noisy alerts.
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 addresses the attack and risk surface, while NIST CSF 2.0 and CIS Controls v8 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 — Improper Offboarding | Ownership gaps appear when credentials outlive the people who created or inherited them. |
| NHI-05 — Overprivileged NHI | The article notes stale service accounts and exposed secrets that still retain active access. | |
| Recommendation — Track orphaned NHIs and revoke or reassign them before leavers, movers, or acquisitions create blind spots. Review NHI privilege scope regularly and remove excess access from credentials that no longer need it. | ||
| NIST CSF 2.0 | PR.AA-05 — Access Permissions, Entitlements and Authorizations | Attribution depends on knowing which entitlements belong to which identity and owner. |
| Recommendation — Maintain current entitlement-to-owner mappings so exposed access can be traced and remediated quickly. | ||
| CIS Controls v8 | CIS-5 — Account Management | The article is fundamentally about managing account ownership across service and human records. |
| Recommendation — Centralise account ownership records and retire or reassign accounts that lack a responsible human. | ||
Key terms
- NHI Ownership Attribution: The process of linking a non-human identity or exposed secret to a human or team that can take action on it. In practice, attribution combines identity, repository, cloud, and workflow signals so remediation, escalation, and audit tasks are assigned without relying on tribal knowledge.
- Orphaned NHI: An orphaned NHI is a non-human identity that remains active without a clear owner, business purpose, or lifecycle path. These identities often survive employee departures, application changes, or missed deprovisioning steps, which makes them difficult to review and risky to leave in place.
- Ownership Hierarchy: A structured fallback chain that identifies primary, secondary, and organisational owners for a secret or non-human identity. It gives security teams a practical escalation path when the creator is absent, the context is lost, or the workload is still business-critical.
