They should use one governance model that assigns ownership, sets approval paths, and measures outcomes across all identity types. Human users, service accounts, and automated systems should all be visible in the same oversight process so exceptions, reviews, and escalation follow the same accountability model.
Why This Matters for Security Teams
A single governance model matters because identity risk is no longer confined to employees or contractors. Service accounts, API keys, bots, and AI agents can outnumber human identities by a wide margin, and their access often persists longer than anyone expects. NHIs are also a common failure point in breaches, which is why NHI governance has become a core part of broader identity oversight rather than a niche technical concern. The visibility gap is the real issue: when teams review humans in one process and machines in another, accountability fragments and exceptions go unmanaged. See the Ultimate Guide to NHIs and the OWASP Non-Human Identity Top 10 for the operational risks that make this approach necessary. In practice, many security teams encounter identity sprawl only after a secrets leak, privilege escalation, or failed offboarding has already created exposure.
How It Works in Practice
Effective governance starts with one inventory and one approval model. Every identity type should be classified by owner, purpose, privilege level, lifespan, and business criticality, then routed through the same oversight workflow. That means human joiner-mover-leaver processes, PAM controls, and NHI lifecycle reviews should feed the same governance register instead of separate spreadsheets or ticket queues. The goal is not to make humans and machines identical, but to make their risk visible in the same control plane.
Practically, organisations should standardise on:
- Named ownership for each identity or credential set, including service accounts and automation.
- Periodic access reviews that cover RBAC, privileged entitlements, and exceptions across all identity classes.
- JIT provisioning for high-risk access, with short-lived credentials and automatic expiry.
- Secrets management that removes long-lived credentials from code, configs, and pipelines.
- Logging and alerting that link each action back to an accountable business or technical owner.
This is consistent with the NIST Cybersecurity Framework 2.0, which emphasises governance, risk management, and measurable outcomes, and with the Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs, which treats lifecycle control as the foundation of NHI security. NHIMG research also shows why this matters: Ultimate Guide to NHIs reports that 97% of NHIs carry excessive privileges, while 96% of organisations store secrets outside secrets managers in vulnerable locations. These controls tend to break down when automation is deployed faster than ownership, because no one can approve, revoke, or attest to what is not explicitly mapped to a responsible system or team.
Common Variations and Edge Cases
Tighter governance often increases operational overhead, so organisations have to balance control depth against delivery speed. That tradeoff is most obvious in CI/CD pipelines, ephemeral cloud workloads, and agentic systems, where access can change per task and static approval models become too slow. Current guidance suggests using the same governance policy, but adapting the enforcement method: humans may use periodic reviews, while machine identities may need runtime checks, short TTLs, and policy-as-code decisions.
There is no universal standard for every exception case yet. For example, some teams still allow long-lived credentials for legacy systems, but those exceptions should be explicit, time-bound, and owned. The same applies to third-party integrations and outsourced operations, where shared responsibility often obscures who can revoke access and who must attest to it. The Top 10 NHI Issues highlights how quickly misconfiguration, excessive privilege, and weak rotation discipline compound into governance failure. For broader identity assurance alignment, OWASP Non-Human Identity Top 10 and NIST guidance both support the same principle: governance should be outcome-based, not identity-type-based. In highly dynamic environments, the model breaks down when ownership is unknown, because policy can be written but never enforced or reviewed.
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 |
|---|---|---|
| NIST CSF 2.0 | GV.RM | Identity governance is a risk-management discipline across all identity types. |
| OWASP Non-Human Identity Top 10 | NHI-03 | Covers NHI lifecycle and credential rotation, central to unified governance. |
| NIST AI RMF | GOVERN | Accountability for autonomous systems fits the governance function of AI RMF. |
Enforce owner-based lifecycle reviews and rotation for every NHI, not just human accounts.
