A structured inventory of the access rights, roles, and permissions that users can request or inherit. Good catalogs make request routing and review possible. Poor catalogs create ambiguity, hidden exceptions, and approvals that do not map cleanly to real application access.
Expanded Definition
An entitlement catalog is the authoritative list of access rights, roles, and permissions that can be requested, approved, provisioned, or inherited across applications and infrastructure. In identity governance, it is the bridge between business language and technical access, because requesters and reviewers need to understand what access actually does before they can approve it responsibly.
For NHI and agentic environments, the catalog must extend beyond human roles to include service accounts, API scopes, workload permissions, and tool access. Its quality determines whether access reviews are meaningful or merely procedural. This is where the distinction from a simple application inventory matters: a catalog describes access semantics, while an inventory only lists systems. That distinction is increasingly important under NIST Cybersecurity Framework 2.0, where governance depends on knowing who, or what, can do what and why. Definitions vary across vendors on whether inherited group membership, application-specific entitlements, and cloud IAM policies belong in the same catalog, but NHI Management Group treats them as part of one control surface when they create reviewable access paths.
The most common misapplication is treating role names as complete access descriptions, which occurs when the catalog omits the underlying permissions, inherited privileges, or non-human execution paths.
Examples and Use Cases
Implementing an entitlement catalog rigorously often introduces maintenance overhead, requiring organisations to balance cleaner governance against the cost of keeping access mappings current as applications and APIs change.
- A finance application catalog entry groups requestable access into clear functions such as invoice approval, refund processing, and report export, so reviewers can approve based on actual duty and risk.
- An NHI catalog includes service-account permissions for database read access, queue publish rights, and vault retrieval scopes, making machine access reviewable alongside human access.
- A cloud platform catalog maps Kubernetes RBAC, cloud IAM roles, and automation credentials to business-friendly labels, reducing confusion during certification campaigns.
- A developer portal uses catalog metadata to route access requests to the correct approver, avoiding ad hoc approvals that bypass ownership controls.
- An organisation aligns catalog entries with implementation guidance from the Ultimate Guide to NHIs and uses the NIST Cybersecurity Framework 2.0 to ensure reviewable, least-privilege access paths.
Where entitlement catalogs are immature, organisations often discover that approvals are attached to vague role names instead of precise permissions, making recertification inconsistent and exception handling opaque.
Why It Matters in NHI Security
Entitlement catalogs matter because NHI risk often grows silently through undocumented permissions, inherited access, and stale service accounts. Without a reliable catalog, access reviews cannot distinguish necessary machine-to-machine permissions from excessive privilege, and zero trust enforcement becomes largely symbolic. This is especially dangerous when secret sprawl or overprovisioned service accounts are already present, because hidden access paths are much harder to contain after compromise.
NHI Management Group reports that Ultimate Guide to NHIs notes 97% of NHIs carry excessive privileges, a statistic that underscores how catalog ambiguity can translate directly into attack surface expansion. An entitlement catalog gives security teams a structured basis for cleanup, review, and offboarding, especially when they need to reconcile human approvals with machine execution rights. It also supports governance evidence for NIST Cybersecurity Framework 2.0 outcomes tied to access management and risk reduction.
Organisations typically encounter the true importance of an entitlement catalog only after a breach review or access audit reveals that a service account had broader permissions than anyone could explain, at which point the catalog becomes operationally unavoidable to address.
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 SP 800-63 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Entitlement catalogs expose excessive and undocumented NHI permissions. |
| NIST CSF 2.0 | PR.AC-4 | Access permissions management depends on knowing what each role or entitlement grants. |
| NIST SP 800-63 | AAL2 | Assurance levels shape how access is granted and reviewed for identities, including NHIs. |
Require cataloged access to align with the assurance level needed for the protected resource.
