A common mistake is assuming approval ends the risk. Access should be reviewable, traceable, and revocable as roles and business needs change. Without that, licenses remain active after work is finished, request decisions lose accountability, and teams miss the chance to remove unused access before it becomes waste or exposure.
Why Organisations Misread Approval as Risk Closure
Access requests are often treated like a ticket that ends when someone clicks approve, but approval is only the start of control. For non-human identities and privileged workflows, the real question is whether access remains necessary, traceable, and revocable over time. NHI Mgmt Group notes that only 20% of organisations have formal processes for offboarding and revoking API keys, which shows how often “approved” becomes “forgotten” in practice.

Security teams get this wrong when they optimise for request throughput instead of lifecycle control. A one-time approval model assumes the access need is static, but business context changes, workloads end, project scopes shift, and credentials outlive the justification that created them. That is a weak fit for OWASP Non-Human Identity Top 10 style risks, where standing access and weak revocation create exposure long after the business event has passed. In practice, many teams discover this only after dormant access is exploited, rather than through intentional review.
How Access Should Behave as an Ongoing Control
Good access governance treats approval as a time-bound decision with continuous validation. The control should answer four questions at runtime and review time: who or what is asking, why the access is needed, whether the request still matches policy, and whether the access can be removed immediately when the purpose ends. That is consistent with NIST guidance on least privilege and access accountability in NIST SP 800-53 Rev. 5 Security and Privacy Controls.
For NHIs, this usually means tying approval to an identity record, an owner, a purpose, and a review schedule. For example, a service account or API key should have a defined business sponsor, expiry date, rotation trigger, and a revocation path that works even if the original requester has left. The practical pattern is simple: grant the minimum access needed, validate usage against policy, and remove or renew access when the underlying task changes. NHI Mgmt Group’s Ultimate Guide to NHIs — Key Challenges and Risks highlights how poor visibility and delayed offboarding turn short-lived access decisions into long-lived exposures.
- Approve access with an explicit purpose, owner, and expiry.
- Review usage patterns to confirm the access is still justified.
- Automate revocation when the task, project, or role ends.
- Record who approved, who owns, and who can remove the access.
- Rotate secrets when the approval basis changes, not only on a calendar.
This breaks down in environments with fragmented ownership and no authoritative inventory, because access cannot be reviewed or revoked reliably when no one can prove what is still active.
Where One-Time Approval Fails in Real Operations
Tighter approval workflows often increase administrative overhead, requiring organisations to balance control against speed and user friction. That tradeoff becomes more visible when access is needed quickly for incident response, CI/CD, or third-party integrations, where manual approvals can slow delivery and encourage shadow access. Current guidance suggests time-boxed access and automated revalidation are better than permanent approval, but there is no universal standard for this yet.
The edge case is not only “too much access,” but also stale approval logic. A request may have been valid for one sprint, one vendor engagement, or one support session, yet remain active for months because no later checkpoint exists. That is why organisations should treat approval as a reusable control state, not a one-off event. In NHI-heavy environments, this is especially important when access is granted to service accounts, tokens, or external automations that can keep operating without human attention. Related incidents such as the 52 NHI Breaches Analysis show how expired intent and persistent access often travel together.
Best practice is evolving toward continuous ownership checks, short-lived credentials, and scheduled recertification. Where organisations still rely on ticket approval alone, the result is usually access drift, weak accountability, and delayed removal of privileges after work is done.
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, NIST SP 800-63, NIST Zero Trust (SP 800-207) 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 | Addresses stale NHI credentials that stay active after approval. |
| NIST CSF 2.0 | PR.AC-1 | Access permissions must be governed beyond the initial approval event. |
| NIST SP 800-63 | Digital identity assurance depends on lifecycle control, not just issuance. | |
| NIST Zero Trust (SP 800-207) | Zero Trust requires continuous verification instead of once-approved trust. | |
| NIST AI RMF | Ongoing oversight is needed when AI or automation holds access over time. |
Set expiry, review, and rotation rules so approved access is not left standing indefinitely.
