They should move from event-only administration to relationship-based governance. That means using joiner-mover-leaver events as triggers, but continuously checking whether access still matches the current relationship, ownership, and policy. The goal is not just faster processing, but lower drift between what the business says and what the directory still allows.
Why Lifecycle Events Alone Do Not Govern Access
Joiner, mover, and leaver workflows are necessary, but they are not sufficient when identities drift faster than HR or ticketing events can keep up. The real risk is that access continues to reflect a past relationship after the business relationship has changed. That gap matters for service accounts, API keys, machine users, and admin roles, where stale permissions often remain invisible until a breach or audit exposes them.
NHIMG research shows why event-only administration falls short: in the Ultimate Guide to NHIs, only 5.7% of organisations report full visibility into their service accounts, while 97% of NHIs carry excessive privileges. When teams rely on one-time lifecycle events, they miss the ongoing question of whether access still matches the current owner, application, environment, and business purpose. That is the difference between provisioning and governance.
Current guidance from the NIST Cybersecurity Framework 2.0 and the OWASP Non-Human Identity Top 10 points toward continuous control validation, not just administrative completion. In practice, many security teams discover stale access only after an incident reveals that the directory was still honoring relationships the business had already ended.
How Relationship-Based Governance Works in Practice
Relationship-based governance uses lifecycle events as triggers, but it does not stop there. Each NHI should have an explicitly managed relationship record: owner, purpose, system, data sensitivity, rotation expectation, and approved scope. When any of those inputs changes, policy should be re-evaluated. That makes the governance model closer to continuous entitlement validation than to a one-time provisioning queue.
A practical program usually includes four steps:
- Bind each NHI to a named business owner and technical steward.
- Track the current relationship, not just the creation event, in a source of truth.
- Reassess privilege when ownership, workload, environment, or vendor relationship changes.
- Revoke, rotate, or re-approve access when the current relationship no longer justifies it.
This model is especially important for long-lived secrets and service accounts. The NHI Lifecycle Management Guide and the static vs dynamic secrets guidance both reflect the same operational truth: the more durable the credential, the more dangerous it becomes when the relationship changes silently. Dynamic credentials, shorter TTLs, and automated revocation reduce the chance that old approvals survive into new contexts.
Implementation is stronger when policy checks are integrated with identity governance, PAM, and secrets management rather than bolted on afterward. That includes periodic attestation, event-driven revalidation, and automated detection of orphaned or over-entitled identities. These controls tend to break down in environments with shared service accounts and undocumented application dependencies because ownership is unclear and no single workflow owns the full relationship.
Where the Standard Approach Breaks Down
Tighter governance often increases operational overhead, requiring organisations to balance faster provisioning against stronger review and revocation discipline. There is no universal standard for this yet, especially where autonomous systems, vendor-managed integrations, and cross-team shared identities overlap.
The biggest edge case is the identity that outlives the team, project, or vendor contract that created it. In those situations, lifecycle events can fire correctly while the actual risk stays unchanged because the relationship was never revalidated. Another common exception is machine-to-machine access inside CI/CD or integration pipelines, where one service account may support multiple workloads and a clean one-to-one ownership model does not exist.
That is why current best practice is evolving toward continuous, relationship-aware control rather than periodic checkbox review. The Top 10 NHI Issues research and the regulatory and audit perspective both support this shift: what matters is not whether a joiner-mover-leaver ticket was closed, but whether the identity still has a defensible relationship to the access it retains. In practice, many organisations find drift only after a review, a breach, or a failed audit reveals that the directory still trusts an old relationship.
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 AI RMF and 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 | Covers lifecycle and ownership drift for non-human identities. |
| OWASP Agentic AI Top 10 | Relevant where autonomous workloads make static access assumptions unsafe. | |
| CSA MAESTRO | Addresses governance for dynamic, multi-system agent and workload relationships. | |
| NIST AI RMF | GOVERN | Supports accountability and ongoing oversight for identity-driven risk decisions. |
| NIST CSF 2.0 | PR.AC-4 | Least-privilege and access management are central to preventing entitlement drift. |
Define explicit workload relationships and recheck access whenever the operating context changes.
