Run authenticated scanning with a session you can verify
An authenticated DAST run is useful only if the scanner reaches the application areas the session was meant to unlock. A saved username, a successful login page, and a completed run are different observations. Record the signed-in workflow before interpreting a clean result.
Give the scanner an identifiable test role
Use a dedicated identity for the approved environment, with synthetic data and the permissions required for the selected workflow. Record the intended role without placing its secret in the report. A broad administrator account can hide the boundary you actually need to examine; an account with too little access can make relevant pages unreachable.
Consider an illustrative customer portal with a billing reader and a billing manager. Both may sign in, but only the manager may change a payment setting. A run using one role does not establish coverage of the other role's behavior. The assessment should name which identity was used for each conclusion.
Check a protected result, not just a login response
Establish what a successful signed-in request looks like. A redirect back to a sign-in page can still end in an HTTP success response. The response status alone therefore does not establish that the protected workflow was reached.
ZAP's authentication documentation describes configuring authentication in an automated run. Its test-request guidance provides a way to check an expected response. Use the relevant tool's actual controls rather than treating one product's settings as universal syntax.
Observe the session during the run
Record a protected page or API response early in the run and check whether the session remains usable later. A session may expire, require a fresh challenge, or lose access after an application change. When that happens, distinguish the work completed under the valid session from the work left incomplete.
If the application uses an external identity provider, establish the allowed navigation and action boundaries separately. A redirect to another host is not permission to test that host. Keep those restrictions in the approved scope and execution configuration.
Preserve a coverage decision
The useful record identifies the account role, application build, approved workflow, reached requests, session-verification evidence, and failures. A route the scanner could not access belongs in the gap list, not in the passed column. Assign the gap to configuration repair, another test method, or an explicit later assessment.
Use the scan checklist to retain the conditions and the coverage guide to interpret what the result supports.
