They often treat them as convenience features instead of governance controls. A catalog is only useful if the app list is current, the approval path reflects real business need, and high-risk apps can be restricted or removed when review findings require it.
Why This Matters for Security Teams
App catalogues and access request workflows are often presented as user experience improvements, but they are actually control points for entitlement governance. If the catalog is stale, the approval chain is ceremonial, or risk-based restrictions are missing, the process becomes a fast lane to over-privilege. That is especially dangerous for non-human identities, where service accounts, API keys, and automation can accumulate access faster than human reviewers can track.
NHIMG’s Ultimate Guide to NHIs notes that 97% of NHIs carry excessive privileges, which shows how quickly convenience can outrun governance. The control problem is not just who can request access, but whether the catalogue reflects the true application estate and whether approvals are tied to business purpose, data sensitivity, and downstream privilege. The OWASP Non-Human Identity Top 10 frames this as an identity assurance issue, not a workflow issue alone.
In practice, many security teams discover catalogue drift only after a review, incident, or audit has already shown that “approved” access no longer matches the actual risk.
How It Works in Practice
A strong app catalogue should function as the front door to policy, not a static menu of software. Teams need current inventory, ownership metadata, risk classification, and enforcement hooks that determine whether access is approved, time-bound, or denied. For NHI use cases, the catalogue should also capture whether an app is machine-to-machine, whether it uses secrets or workload identity, and what downstream systems it can reach. That matters because a request for a simple integration can translate into broad token scope, lateral movement, or privileged API access.
Current guidance suggests separating request intake from approval logic. The request form may be simple, but the decision should be context-aware: business justification, data class, environment, and target privilege should all influence the outcome. This is where Ultimate Guide to NHIs — Key Challenges and Risks is useful, because the biggest failure is often not initial approval but the inability to revoke, rotate, or reclassify access when the app’s use changes.
- Use the catalogue as the authoritative source for app ownership and risk tier.
- Map request approvals to actual business need, not just manager sign-off.
- Require expiration or review dates for sensitive access, especially for NHIs.
- Connect catalogue records to enforcement so restricted apps can be hidden, disabled, or removed.
Well-run access request processes also link to evidence: who approved, what control was invoked, and whether the access was later used as intended. These controls tend to break down when application ownership is unclear across mergers, shadow IT, and CI/CD-driven provisioning because the catalogue no longer reflects the real system of record.
Common Variations and Edge Cases
Tighter catalogue governance often increases administrative overhead, requiring organisations to balance speed of request fulfilment against confidence that access is justified. That tradeoff becomes sharper in large enterprises, partner ecosystems, and DevOps-heavy environments where applications appear and disappear faster than normal review cycles.
One common edge case is “temporary” access that becomes de facto standing access because no one owns the removal step. Another is catalogue sprawl, where duplicate entries, deprecated apps, or environment-specific variants obscure which control path should apply. Best practice is evolving, but there is no universal standard for this yet: some organisations use policy-as-code to gate approval, while others rely on GRC workflows plus quarterly recertification. The right answer is the one that can actually remove access when the business case ends.
For teams building stronger governance, the key question is not whether an app can be requested, but whether the request process can prove the app exists, the approver is accountable, and the entitlement can be revoked cleanly. The NHI lens helps here because catalogue weakness often shows up first in machine access, not human access.
That pattern is visible across 52 NHI Breaches Analysis, where weak identity and entitlement hygiene repeatedly outlasts the original approval event.
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-01 | App catalogues fail when NHI inventory and ownership are incomplete. |
| NIST CSF 2.0 | PR.AC-4 | Access requests should enforce least privilege and approved entitlement changes. |
| NIST AI RMF | Risk governance applies when workflows control autonomous or automated access decisions. |
Use AI RMF governance to define approval accountability, review triggers, and revocation criteria.
