Governance becomes inconsistent because approvals are hard to verify, removals are easy to miss, and audit evidence is scattered. Over time, entitlement creep grows faster than review cycles, and access becomes a record of old decisions rather than current business need. That is a control failure, not just an operational inconvenience.
Why This Matters for Security Teams
When access decisions stay in tickets and spreadsheets, they stop behaving like controls and start behaving like stale records. That creates a gap between what was approved and what is still valid, which is especially dangerous for service accounts, API keys, and other NHIs that do not self-correct. Current guidance from the OWASP Non-Human Identity Top 10 treats this as a governance failure because entitlements, secrets, and offboarding need continuous state, not periodic paperwork.
The operational risk is not just delay. Manual tracking makes it hard to prove who approved what, whether removal actually happened, and whether a change request reflects current business need. NHI Management Group research shows how often this breaks down in practice: the Ultimate Guide to NHIs notes that only 20% of organisations have formal processes for offboarding and revoking API keys. In practice, many security teams encounter over-privilege only after an audit, a failed offboarding, or a secrets exposure has already occurred, rather than through intentional control design.
How It Works in Practice
The practical fix is to move from document-driven approvals to system-enforced access state. That means identities, entitlements, and secrets should live in authoritative platforms where changes are logged, time-bound, and revocable. For NHIs, this usually includes secrets managers, IAM, PAM, CI/CD policy gates, and workload identity mechanisms that can be evaluated at runtime rather than at the end of a review cycle. NHI Mgmt Group’s Ultimate Guide to NHIs — Key Challenges and Risks highlights why this matters: manual handling creates blind spots across rotation, offboarding, and visibility.
A more durable workflow typically includes:
- Authoritative ownership for each NHI, with a named system or team responsible for approvals and removal.
- Short-lived credentials or JIT issuance for task-specific access, so approval does not become standing privilege.
- Automated deprovisioning on role change, service retirement, pipeline completion, or inactivity thresholds.
- Central logging of entitlement changes, secret rotation, and revocation events for audit evidence.
- Policy checks at request time, not just at review time, so access reflects current context.
This aligns with the control intent in the OWASP Non-Human Identity Top 10 and the broader lifecycle focus in NHI governance. The goal is not to eliminate approvals, but to ensure approvals result in machine-enforced state change rather than an entry in a spreadsheet. These controls tend to break down when access is shared across multiple legacy systems because no single system can reliably enforce or revoke the full entitlement set.
Common Variations and Edge Cases
Tighter access governance often increases administrative overhead, so organisations have to balance auditability against operational speed. That tradeoff is real in environments with many temporary integrations, vendor connections, or high-churn CI/CD pipelines, where manual review can become a bottleneck if automation is missing.
There is no universal standard for every workflow yet, but current guidance suggests treating exceptions as time-bound and explicitly owned, not as informal approvals stored in email or chat. Legacy systems may still require ticket-based workflows for traceability, but those tickets should trigger enforced changes in IAM, PAM, or secrets tooling rather than serve as the source of truth. This is where spreadsheet-led governance tends to fail: it records intent, not state.
For organisations trying to reduce risk quickly, the most practical starting point is to identify where approvals, secrets, and revocations are still disconnected. NHI Mgmt Group’s 52 NHI Breaches Analysis is useful for understanding how often governance gaps turn into exposure, while OWASP’s NHI guidance helps translate that insight into repeatable control design.
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 |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-03 | Manual approvals hinder rotation and revocation, which this control addresses. |
| NIST CSF 2.0 | PR.AC-4 | Access permissions must be managed and reviewed continuously, not manually tracked. |
| NIST AI RMF | GOVERN | Stale access records undermine accountable governance for machine identities. |
Replace spreadsheet-based approvals with enforced NHI rotation and revocation workflows.
