They should unify app inventory, access review, and remediation workflows so cloud policy can be enforced from the identity system outward. Separate ownership usually leaves gaps in accountability, especially when service accounts, delegated access, and unmanaged apps are involved.
Why This Matters for Security Teams
When cloud security and identity governance sit in different operating models, the result is usually fragmented control over the same access paths. Identity teams may review entitlements while cloud teams enforce policy, but service accounts, delegated admin roles, and shadow SaaS integrations often fall between them. That gap matters because NHIs do not behave like human users, and static ownership models fail when access is provisioned outside a single system of record.
Current guidance from NIST Cybersecurity Framework 2.0 points toward integrated governance across inventory, access, and response. NHIMG research on the Ultimate Guide to NHIs shows that lifecycle control only works when discovery, review, and remediation are linked, not handled as separate queues. Without that linkage, over-permissioned service identities linger long after the original business need has changed.
In practice, many security teams encounter excessive cloud privilege only after an audit, a breach review, or a stalled incident response reveals that no single owner can prove who approved the access.
How It Works in Practice
The practical answer is to make identity the control plane for cloud access, not a downstream reviewer of it. Teams should unify application inventory, entitlement review, and remediation workflows so that every cloud application, workload identity, and service account has a mapped owner, a business purpose, and a documented revocation path. That gives identity governance the context needed to challenge risky cloud access before it becomes persistent privilege.
A strong operating model usually includes four linked steps:
- Discover cloud apps, service principals, OAuth grants, and machine identities into one inventory.
- Classify each identity by business owner, environment, and access sensitivity.
- Route periodic access reviews through the identity platform, but trigger cloud-side enforcement automatically when access is out of policy.
- Revoke, rotate, or downgrade access from the same workflow that generated the finding.
This is where NHI lifecycle discipline matters. The NHI Lifecycle Management Guide and the Top 10 NHI Issues both reinforce that access review without remediation is only reporting, not control. For implementation grounding, NIST CSF 2.0 supports asset visibility, governance, and response as linked outcomes rather than separate functions. The operational goal is simple: one inventory, one decision path, one accountable owner. These controls tend to break down in multi-cloud environments with decentralized app onboarding because shadow integrations and inherited permissions outpace manual review cycles.
Common Variations and Edge Cases
Tighter integration between cloud and identity teams often increases governance overhead at first, requiring organisations to balance better control against slower change management. That tradeoff is real, especially in environments with frequent deployments, inherited enterprise tenants, or third-party managed services that cannot be reviewed like standard employee access.
Best practice is evolving, but current guidance suggests treating these exceptions explicitly rather than allowing them to bypass policy. For example, platform-admin service accounts may need separate review cadences, while delegated SaaS access may require scoped consent and expiration controls. In some organisations, the cloud team retains technical enforcement while identity governance owns attestation and exception handling; in others, a shared control tower model works better. What matters is not which team “owns” the tool, but whether one workflow can answer who approved the access, why it exists, and how it is removed.
NHIMG research shows that visibility gaps remain common in connected identity ecosystems, particularly where third-party access is involved, so teams should validate ownership for every non-human account rather than assuming directory membership is enough. The 52 NHI Breaches Analysis is a useful reminder that fragmented accountability is a recurring failure mode, not an edge case. The model becomes weakest when cloud policy can be changed outside identity governance, because remediation then depends on informal coordination instead of enforceable workflow.
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 and CSA MAESTRO address the attack and risk surface, while NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Inventory and ownership gaps are a core NHI discovery risk. |
| NIST CSF 2.0 | PR.AC-4 | Identity and cloud access need coordinated least-privilege enforcement. |
| CSA MAESTRO | GOV-02 | Shared governance is needed when cloud and identity controls span multiple teams. |
Build one authoritative inventory for all non-human identities, then assign owners before access reviews begin.
