Configuring Form Authentication in Netsparker Enterprise

When using Netsparker Enterprise to scan a web application that has a form based login, you'll need to configure the credentials and verify the session. Session verification is important, because you need to confirm that the configuration is correct, and that the scanner can differentiate between a logged in and a logged out session.

Session verification allows the scanner to identify a terminated session, so if it happens during a web vulnerability scan, the scanner can automatically log back in again, ensuring all password protected pages are scanned.

How to Configure Form Authentication

  1. Log in to Netsparker Enterprise.
  2. From the main menu, click Scans, then New Scan (or New Group Scan). The New Scan window is displayed.
  3. From the Scan Options section, select Form Authentication. The Form Authentication section is displayed.
  4. Enable the Form Authentication checkbox.
  5. In the Login Form URL field, enter the URL of the login form whose credentials you want to configure.

  1. In the Personas section, click New Persona. A new row is displayed.
  2. In the Username field, enter the username.
  3. In the Password field, enter the password.
You can specify multiple sets of credentials, and select the Active option next to the credentials Netsparker Enterprise should use during the upcoming scan.

  1. Click Verify Login & Logout so the scanner can test the login and determine a pattern to use to automatically detect logged in and logged out sessions.

What Happens When Verifying Form Authentication Configuration and Session

During the session verification process, the Verify Form Authentication window is displayed, showing the progress of the test.

Netsparker Cloud verifying the credentials and the session by logging in on the target web application

During verification, the following happens:

  1. On the left, the scanner logs in to the web application using the supplied credentials and displays a logged in session.
  2. On the right, the scanner displays how the web application looks when not logged in. It also displays the Logout Detection pattern.

Once the test is ready, it is important that you:

  1. Confirm that both logged in and logged out sessions look as expected.
  2. Confirm that the logout detection pattern is correct, since this will be used by the scanner to identify a terminated session and log back in to continue the scan.
