Quality & security

Identity & application security

SSO, OAuth 2.0, OpenID Connect, SAML where required, role-based access, tenant isolation, secret management, and audit trails. Apply least privilege and validate authorization on the server.

Illustrative access model — define your own roles
Operation	Requester	Team manager	Service process
Read own request	Allowed	Within assigned team	Only with explicit scope
Approve a request	Not allowed	Within assigned authority	Not allowed by default
Change organization settings	Not allowed	Not allowed by default	Not allowed by default

Authentication establishes who is calling. Authorization decides what that identity can do to a particular record. Check both the operation and the resource boundary on the server, including tenant ownership.

Follow one protected operation

01
Identity
Validate the session or service credential.
02
Resource
Load the record within the permitted tenant boundary.
03
Policy
Check the role and the requested state transition.
04
Audit
Record the result with an appropriate actor reference.

Why test cross-tenant access explicitly?

A valid user may still be forbidden from another organization’s records. Tests should attempt that access directly, including guessed identifiers and background operations, rather than relying on hidden interface controls.
