Ownership should sit across IAM, cloud security, and network teams, because the failure spans all three control planes. A role review that ignores VPN keys, deployment outputs, or service metadata is incomplete. The practical test is whether one access decision could expose both cloud resources and connected internal networks.
Why This Matters for Security Teams
Ownership of roles, permissions, and network-connected secrets is not a narrow IAM question. It is a control-plane issue that crosses identity, cloud, and network boundaries, which is why partial reviews miss the real blast radius. A role can look acceptable on paper while still carrying VPN material, deployment tokens, or service metadata that opens internal paths as well as cloud resources.
That is the pattern NHI Management Group highlights in the Guide to the Secret Sprawl Challenge: secrets and access often accumulate faster than teams can trace them back to business ownership. The issue becomes sharper when secrets are embedded in automation, because the reviewer is no longer assessing a person’s access profile but a machine path that can be reused, copied, or chained into other systems.
Security teams also need to account for the practical gap between policy and reality. The OWASP Non-Human Identity Top 10 treats overprivileged non-human access and exposed secrets as recurring failure modes, not edge cases. In practice, many security teams encounter cross-domain exposure only after a leaked secret or mis-scoped role has already been used to reach internal networks.
How It Works in Practice
The cleanest ownership model is shared accountability with a single review process. IAM should own role design and entitlement logic, cloud security should own resource and workload permissions, and network security should own how secrets connect to internal paths, VPNs, and segmented environments. The reviewer does not need to be the same team for every asset, but the process must be coordinated enough to answer one question: could this access path expose both cloud control and network reach?
For that reason, effective reviews should combine identity inventory, secret inventory, and network path mapping. A role review should include service accounts, deployment pipelines, API keys, certificates, device tokens, and any secret that can be used to authenticate into internal services. Where possible, teams should verify whether a secret is long-lived or ephemeral, whether it is tied to a workload identity, and whether its use is constrained by policy at request time. That aligns with the runtime evaluation model described in NIST SP 800-207 Zero Trust Architecture, which emphasizes continuous verification over implicit trust.
In NHI programs, the most useful operational question is not “who owns the secret?” but “who can approve removal, rotation, or scope reduction without breaking delivery?” That question becomes even more important in environments that rely on CI/CD, infrastructure-as-code, and machine-to-machine trust. The Ultimate Guide to NHIs — Static vs Dynamic Secrets is useful here because it frames the tradeoff between persistent credentials and shorter-lived, easier-to-govern access paths. Review cycles tend to break down when ownership is split but the system has no shared evidence trail for where a role ends and a network-connected secret begins.
Common Variations and Edge Cases
Tighter ownership often increases coordination overhead, so organisations have to balance speed against assurance. That tradeoff is especially visible when a platform team manages the technical controls but a separate security team owns the policy outcome. Current guidance suggests this is acceptable only if the review process has one accountable decision-maker and clear escalation for disputed entitlements.
Edge cases usually appear in hybrid networks, acquired environments, and vendor-managed tooling. A cloud role may be harmless until it can retrieve a secret that bridges into a private segment. A network token may seem operational until it also grants access to a deployment pipeline. In these cases, the reviewer should inspect transitive access, not just direct permissions. The 52 NHI Breaches Analysis shows why this matters: compromise often moves through connected identities and secrets rather than a single obvious control failure.
There is no universal standard for this yet, but the best practice is to assign one coordinating owner for the review workflow, then require IAM, cloud, and network sign-off for assets that can cross boundaries. That model works best when the review cadence is tied to secret rotation, role recertification, and network exposure checks. It becomes less effective when teams rely on separate tickets, because no single review can prove the full access chain.
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 Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-03 | Covers overprivileged non-human access and weak secret governance. |
| NIST CSF 2.0 | PR.AC-4 | Access permissions must be managed consistently across identities and connected assets. |
| NIST Zero Trust (SP 800-207) | Zero Trust requires continuous evaluation of access that spans cloud and network paths. |
Apply continuous verification to each role and secret so connected network access is not implicitly trusted.
