Inventory the API you intend to assess
List environments, base URLs, versions, owners, sensitive operations, and excluded services. OpenAPI specifications can help describe operations, but they may be incomplete or out of date. Confirm the live API and agreed boundaries.
Make identities and expectations explicit
Prepare approved accounts for the roles and tenants that matter. Record expected object ownership and permissions. Ask separate questions about reading a record, changing its fields, and calling a privileged operation.
Use a role–resource matrix
For an illustrative invoice API, a member may read their tenant’s invoices, a billing administrator may export them, and a user in another tenant should have neither permission. The matrix defines the expected result before testing begins.
| Identity | Own tenant: read | Own tenant: export | Other tenant |
|---|---|---|---|
| Member | Allowed | Not allowed | Not allowed |
| Billing administrator | Allowed | Allowed | Not allowed |
Validate the security conclusion
A request returning HTTP 200 does not prove a security defect. Review the response content, expected permission, identity context, and impact. Protect tokens and unrelated records in any shared evidence.
Give the owner a focused remediation path
Tie the issue to the affected authorization boundary or behavior. The retest should revisit the original role/object combination and relevant allowed behavior, within the agreed scope.
Discuss coverage with Turix
API assessment is a product focus. Supported specifications, authentication methods, protocol handling, multi-role checks, and reporting are requirements to confirm, not comprehensive capabilities advertised as available today.
