Multiple identities increase the chance of inconsistent permissions, orphaned accounts, and unclear ownership. Standing access makes it harder to prove why access existed at a specific moment and expands the blast radius of a compromised account. In audits, that usually translates into fragmented evidence, slower reconciliation, and greater control gaps.
Why This Matters for Security Teams
Multiple identities and standing access are not just an administrative nuisance. They make it difficult to answer basic audit questions such as who owned the access, what it was used for, and whether it was still justified at the time. That is especially dangerous in cloud operations, where entitlements, tokens, service accounts, and API keys can all drift independently across platforms and projects.
This is why NHIs are a recurring audit issue in Ultimate Guide to NHIs — Regulatory and Audit Perspectives. The governance problem is not only excess privilege, but also evidence quality. If access is persistent, reviewers must reconstruct intent after the fact, often from incomplete logs and disconnected ownership records. That increases control gaps and weakens confidence in attestations. The NIST Cybersecurity Framework 2.0 still expects accountable access governance, but cloud reality often fragments that accountability across identities and accounts.
NHIMG research also shows how common the maturity gap remains: The 2024 Non-Human Identity Security Report found that 88.5% of organisations say their non-human IAM practices lag behind or are merely on par with human IAM efforts. In practice, many security teams discover the audit problem only after they cannot explain a live entitlement during review or incident response, rather than through intentional control testing.
How It Works in Practice
The security risk starts with identity sprawl. A single workload may use a human owner, one or more service accounts, cloud-native roles, CI/CD credentials, and application secrets. If each identity has standing access, then permissions remain available long after the original task, deployment, or business need has changed. That creates persistent exposure and makes it harder to prove least privilege.
Current guidance from the OWASP Non-Human Identity Top 10 and Top 10 NHI Issues points to the same operational pattern: rotate away from standing secrets, assign explicit ownership, and constrain access to the smallest workable scope. In practice, that means every identity should answer four questions at all times: what it is, who owns it, what it can reach, and how it is revoked. Pair that with NHI Lifecycle Management Guide discipline so creation, change, review, and decommissioning are tied to the workload lifecycle rather than left to platform defaults.
- Use one workload identity per function or deployment boundary instead of sharing accounts across teams.
- Prefer short-lived credentials and ephemeral tokens over long-lived secrets that survive project changes.
- Bind ownership and expiration to the asset record so auditors can trace access back to a business purpose.
- Log grant, use, and revocation events in a way that can be reconciled across cloud and CI/CD systems.
The NIST SP 800-53 Rev 5 Security and Privacy Controls reinforces access review and authorization accountability, but these controls tend to break down when identities are cloned across accounts and the organization cannot tie each grant to a current workload owner.
Common Variations and Edge Cases
Tighter access control often increases operational overhead, so organisations have to balance auditability against deployment speed and platform complexity. That tradeoff is real in hybrid cloud, multi-account estates, and fast-moving DevOps environments where teams prefer reusable templates and shared automation identities.
Best practice is evolving, but current guidance suggests that shared identities should be treated as exceptions, not the default. Some environments still rely on standing access for legacy integrations, disaster recovery, or vendor-operated services, and those cases need compensating controls such as tighter logging, scoped permissions, and explicit review cadences. Where OAuth apps, federated CI/CD, or cross-account roles are involved, the hard part is often not the permission itself but proving whether the access was still appropriate at a given moment. NHIMG notes in Ultimate Guide to NHIs — Key Challenges and Risks that inconsistent visibility and lifecycle management are recurring failure points, and that aligns with what auditors see.
There is no universal standard for every cloud exception yet. The practical answer is to reduce standing access where possible, document the exceptions where not, and make revocation and ownership traceable enough to survive audit and incident review.
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, OWASP Agentic AI Top 10 and CSA MAESTRO 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 | Standing access and stale secrets are core NHI control failures. |
| OWASP Agentic AI Top 10 | Autonomous workloads need runtime authorisation, not static permission sets. | |
| CSA MAESTRO | MAESTRO addresses governance for cloud-native and agentic workload identities. | |
| NIST CSF 2.0 | PR.AC-4 | Access permissions management maps directly to review and least-privilege concerns. |
| NIST AI RMF | AI RMF governance helps manage accountability for dynamic, tool-using systems. |
Inventory each non-human identity, remove standing access, and rotate or revoke credentials on a defined lifecycle.
