Manual queues make access feel expensive, so teams approve broader grants to reduce repeat tickets. Over time, that creates persistent access that no longer matches actual need. The fix is not just faster ticketing. It is a workflow that can approve narrowly scoped entitlements without forcing users or reviewers into exceptions.
Why This Matters for Security Teams
Manual access requests often turn temporary need into durable entitlement. When reviewers are asked to process the same request repeatedly, the path of least resistance is to approve broader access once and leave it in place. That shifts the control objective from “grant what is needed now” to “reduce ticket volume,” which is how standing privilege creeps into service accounts, API keys, and human access alike.
This is not just an operational nuisance. Standing privilege expands blast radius, weakens separation of duties, and makes later review harder because the original justification is buried in old tickets. NHI Mgmt Group notes that 97% of NHIs carry excessive privileges, and that risk is amplified when approvals are manually handled instead of bound to a narrow, time-limited workflow in the first place. For broader background, see the Ultimate Guide to NHIs and the OWASP Non-Human Identity Top 10.
In practice, many security teams discover standing privilege only after an access review or incident reveals that “temporary” access was never removed.
How It Works in Practice
Manual queues create friction in three places: requester effort, approver effort, and remediation effort. Each step encourages shortcuts. Requesters ask for more than they need so they do not have to return later. Approvers broaden scope so they can move tickets faster. Administrators keep access persistent because revocation is easy to postpone and hard to verify. The result is a privilege profile that drifts away from actual business need.
A better workflow separates approval from permanence. Current best practice is to approve the smallest useful entitlement, attach a clear purpose, and make the grant expire automatically. For NHI and agentic workloads, that usually means just-in-time provisioning, short-lived secrets, and workload identity rather than long-lived static credentials. NHI Mgmt Group’s research shows that only 20% of organisations have formal processes for offboarding and revoking API keys, which is one reason stale access survives long after the original request is forgotten. See the 52 NHI Breaches Analysis and the Ultimate Guide to NHIs — Key Challenges and Risks.
- Use pre-approved policy boundaries so reviewers confirm context, not permanent entitlement.
- Issue access with a short TTL and revoke automatically on task completion or expiry.
- Bind approval to workload identity, so the request is tied to what the workload is, not just who asked.
- Log purpose, duration, and resource scope so reviews can verify whether the grant matched the request.
These controls tend to break down in legacy environments where applications cannot tolerate token rotation, shared accounts mask the real user, or downstream systems only support coarse role grants.
Common Variations and Edge Cases
Tighter approval workflows often increase operational overhead, so organisations have to balance speed against control. That tradeoff is real: a highly manual process can slow delivery, while an overly broad self-service model can normalise standing privilege. Current guidance suggests that the answer is not fewer approvals, but smarter approvals with narrower scope and automatic expiry.
Some environments need special handling. Shared admin accounts usually require additional compensating controls because it is hard to attribute one request to one outcome. High-churn CI/CD pipelines may need policy-driven issuance rather than ticket-driven approval, because manual queues cannot keep up with runtime demand. For agentic systems, the risk is even higher because autonomous behaviour is not predictable enough for static role design. The practical fix is to evaluate access at request time with context, not to grant once and hope review will catch the excess later. Related governance patterns are discussed in the Ultimate Guide to NHIs and the OWASP Non-Human Identity Top 10.
There is no universal standard for this yet, but the direction is clear: reduce manual exception handling, shorten entitlement lifetimes, and make standing privilege the exception rather than the default.
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 | Manual requests often create stale or excessive NHI access that this control targets. |
| NIST CSF 2.0 | PR.AC-4 | Least privilege and access governance address permission creep from manual approvals. |
| NIST Zero Trust (SP 800-207) | Zero trust reduces reliance on durable trust from one-time manual approvals. |
Grant NHI access with narrow scope and automated expiry, then remove any lingering standing privilege.
