The accountable party should be the business or technical owner of the identity, not a periodic review queue. Accountability must be structural, because service accounts and API keys outlive meetings, tickets, and staffing changes. Clear ownership is what allows remediation to happen before exposure turns into an incident.
Why This Matters for Security Teams
Risky non-human access is not just a permissions problem. It is an ownership problem that becomes a containment problem when service accounts, API keys, bots, and workload identities are left without a named business or technical steward. NHI Management Group research shows that only 5.7% of organisations have full visibility into their service accounts, which means accountability gaps are usually hidden until a review, audit, or incident exposes them. That is why guidance from the Ultimate Guide to NHIs — Key Challenges and Risks matters here: if nobody owns the identity, nobody is responsible for reducing its standing privilege, rotation risk, or offboarding delay.
The practical question is not who signed the ticket last quarter, but who can actually approve remediation now. That usually means the team that operates the workload, platform, or integration, with security providing policy and enforcement. The same operating model is echoed in the OWASP Non-Human Identity Top 10, which treats unmanaged NHI risk as a recurring control failure, not a one-time hygiene issue. In practice, many security teams encounter ownership ambiguity only after a secret leak or privilege abuse has already occurred, rather than through intentional governance.
How It Works in Practice
Accountability should be structural, not periodic. The owner of a risky NHI should be the person or team that can answer three questions at any moment: what workload uses it, what business function it supports, and what happens if it is revoked. That makes remediation actionable. Security can identify the exposure, but the owner must decide whether the identity is still needed, whether it should be replaced with just-in-time JIT credentials, and whether long-lived secrets can be removed in favour of short-lived tokens.
For agentic systems and autonomous workloads, this becomes even more important because the identity is not just a static account. The workload may act on goals, chain tools, and request new permissions at runtime. Current guidance suggests that static RBAC alone is often too blunt for this environment. Better practice is to pair workload identity with runtime policy checks, so access can be evaluated in context rather than granted once and forgotten. That aligns with the governance emphasis in the Ultimate Guide to NHIs and the accountability expectations in NIST Cybersecurity Framework 2.0.
- Assign a named owner for every service account, key, token, and agent workload.
- Bind ownership to the application or business service, not to a generic queue or periodic reviewer.
- Require the owner to approve revocation, rotation, and replacement paths.
- Use policy and telemetry to trigger action when access exceeds the workload’s normal purpose.
Where possible, tie ownership to the system of record for the workload identity itself, so an exposed secret can be traced back to the team that can remediate it. These controls tend to break down when identities are embedded in legacy CI/CD pipelines because no single team can safely revoke them without stopping production.
Common Variations and Edge Cases
Tighter ownership often increases operational overhead, requiring organisations to balance speed against control. That tradeoff is real in shared platforms, outsourced integrations, and machine-to-machine estates where one identity may support multiple services. In those cases, best practice is evolving, and there is no universal standard for this yet: some organisations assign a primary owner plus named secondary stewards, while others map accountability to the consuming service rather than the issuing platform.
The main exception is emergency break-glass access. A temporary exception may be justified, but it still needs a durable owner and a clear expiry path. The same applies to third-party integrations, where business ownership may sit with the internal vendor manager while technical ownership sits with the platform team. NHI Management Group research on 52 NHI Breaches Analysis and the broader Top 10 NHI Issues both point to the same pattern: risk persists when nobody can act quickly enough to revoke or reassign access. That is why the right answer is not “security,” and it is not “the reviewer.” It is the owner who can make the identity safe or retire it entirely, with security enforcing the control model. The NIST Cybersecurity Framework 2.0 supports that separation of governance and execution, while the OWASP Non-Human Identity Top 10 highlights why unmanaged access keeps resurfacing in real environments.
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 | Focuses on rotation and lifecycle control for risky non-human credentials. |
| NIST CSF 2.0 | PR.AC-4 | Least-privilege access governance depends on clear identity ownership. |
| NIST AI RMF | Accountability is a core GOVERN function for autonomous or agent-driven systems. |
Define human accountability for each autonomous workload and require traceable remediation paths.
