An unauthenticated scan sees the public edge of an application. Many material workflows—account management, billing, administration and user-specific data—exist behind login. Authenticated DAST can reach them, but it also introduces state, safety and authorization requirements.
Authentication is a workflow
A scanner may need a form or JSON login, an OAuth browser flow, a recorded browser sequence, an API collection or a reusable test session. Success must be verified through an authenticated marker, not assumed from a successful HTTP response.
Authorization needs more than one identity
Broken object-level and function-level authorization require comparison between users or roles. A response is suspicious only when the scanner can establish what one identity should and should not access. Test accounts and expected permissions must be designed deliberately.
Safety boundaries
Use non-production data where possible. Define allowed methods, domains, rate, destructive-action exclusions and cleanup. Credentials must be scoped, stored safely and excluded from reports and logs.
Evidence and replay
Retain the request shape, identity role, expected decision and redacted response evidence needed to reproduce the finding. Do not expose session tokens or sensitive records.
QFinch authenticated/API DAST remains a controlled-preview capability while broader login formats and replay scenarios are validated.
Next step: Prepare dedicated test identities and an authorization matrix before enabling active authenticated scanning.
