How should organisations design an access request catalog so users request the right access without exposing unnecessary permissions?

How to structure a requestable access catalog

An effective catalog is a governed product list, not a raw dump of every entitlement. The design goal is to make the right request easy and defensible, while making excessive access hard to obtain by accident. That means every item should have a business-readable name, a clear owner, a known approval path, and enough context for a requester to understand what they are asking for before they submit it.

The catalog should be organised around requestable access units, such as roles, access bundles, or templates, rather than individual permissions wherever possible. That reduces cognitive load, keeps approvals meaningful, and avoids exposing internal privilege structure that ordinary users do not need to see. Good catalog design also separates stable, repeatable access from sensitive, exceptional, or administrative access so the self-service experience stays safe by default.

For the underlying identity and governance model, it helps to anchor the catalog to IAM and IGA Basics, because request design only works when entitlement naming, ownership, approval logic, and review cycles are aligned. If the catalog is built on the same governed access model as provisioning and access review, users see fewer choices, approvers see clearer context, and the organisation exposes less unnecessary privilege.

What belongs in the catalog, and what should stay hidden

A good catalog shows only access that a requester can meaningfully choose, justify, and receive without specialist interpretation. That usually means business roles, application bundles, environment-specific templates, and preapproved access patterns. It does not mean every entitlement, every inherited permission, or every administrative pathway should be visible to the average user.

Keep privileged access, break-glass access, orphaned entitlements, obsolete permissions, and highly technical control items out of ordinary self-service unless there is a tightly controlled exception process. This prevents users from requesting access they cannot assess properly and reduces the chance that the catalog itself becomes a discovery mechanism for excess privilege. The cleaner the list, the less likely it is that requesters will choose the wrong item simply because it looks available.

Grouping matters because users think in tasks, not in permissions. A well-designed catalog maps access to job functions, systems, or business outcomes, then resolves that request into the correct downstream entitlements. That approach also makes approvals more consistent, because approvers can evaluate whether the requested access fits the role, the project, or the exception reason instead of having to interpret technical permission names.

How to keep the catalog from creating privilege creep

Catalogs drift when they are treated as a static list. Over time, new applications, duplicate roles, legacy permissions, and convenience-based exceptions accumulate, and the catalog starts to expose more access than people actually need. That is why catalog design has to be tied to periodic entitlement rationalisation, ownership checks, and removal of items that no longer have a clear business justification.

A smaller, better-governed catalog usually produces better outcomes than an exhaustive one. Stable templates should be updated when applications or responsibilities change, and any request path that repeatedly requires exception handling should be converted into a governed role or removed from self-service. If a catalog item is difficult to approve, difficult to explain, or difficult to review later, it is probably too granular or too risky for general request use.

There is also a security benefit in reducing the discoverability of excess access. The fewer raw entitlements users can browse, the less opportunity there is for “shopping” for powerful permissions or for normalising access that should remain exceptional. That is why mature access request programs pair a curated catalog with strong review of both what is requested and what is published.

Risk and Threat Considerations

An overexposed catalog can become a privilege escalation path in practice, even if it was intended as a convenience tool. When requesters can see or request more access than they should, the organisation increases the chance of excessive privilege, approval fatigue, and accidental selection of the wrong entitlement.

Failure mechanism: Uncurated catalogs surface too many permissions, making it easier for users to request broad access, for approvers to miss excessive scope, and for legacy items to remain available after their business justification has expired.

Impact: The result is privilege creep, larger blast radius after compromise, and a harder audit story because the requested item no longer clearly matches the business need.

Practitioner Guidance

What to prioritise: Start with the smallest set of requestable items that still covers common business needs. If a permission is too technical for a business user to judge, it should usually be wrapped in a governed role or kept out of ordinary request paths.

What to verify: Every catalog item should have a named owner, a plain-language description, a defined approver, and a review date. If any of those are missing, treat the item as incomplete rather than convenient.

Common mistake: Teams often publish the catalog they have, not the catalog they want users to choose from. That shortcut turns access request into a front door for entitlement sprawl.

Practitioner takeaway: The best catalog is not the most complete one, it is the one that safely narrows choice to access that can be understood, justified, approved, and later defended.
