A Client Portal Needs Record-Level Access Rules, Not Just Login Roles

A 3PL customer logs in and sees the right dashboard. That does not establish that every shipment document, invoice link, or export is restricted correctly.

The business needs to define access to the underlying records, not only access to screens.

OWASP describes broken object-level authorization as a failure to enforce whether a user may act on a particular object. It recommends checks at the points where records are accessed. OWASP also suggests random, unpredictable record IDs, but lists them alongside authorization checks, not in place of them. OWASP object-level authorization guidance.

Describe access in business terms

Our recommendation is to map four dimensions: role, client or organizational relationship, record, and action.

For example, a hypothetical client user might view their company's shipments but not another client's invoices. A destination operator might update assigned package statuses but not approve billing adjustments. An internal reviewer might need a limited cross-client view.

The actual policy must reflect your operation. “Admin can do everything” should not replace a discussion of responsibilities and sensitive actions.

Include the less visible routes

Apply the requirements to document downloads, search results, bulk exports, notifications, and API access as well as ordinary pages. Define how access changes when staff move roles, a partner relationship ends, or a client account closes.

The application needs server-side enforcement. Hiding a button can improve the interface, but does not establish that the underlying action is restricted.

Review with separate test identities

Ask the delivery team to demonstrate the approved permission matrix in an authorized test environment using different client and operator accounts. Include allowed and denied cases for sensitive records and actions.

Record the expected outcome and verify it again when permissions or integrations change. This is an acceptance requirement, not a request to test systems without authorization.
