You can perform a pre-scan check to:

• Make sure that Burp Suite DAST can reach your target URLs.
• Review and edit your recorded login sequences, so you can make sure that they log in to your sites successfully.

Burp Suite DAST prompts you to perform a pre-scan check when you add a new web app site. You can also perform a pre-scan check on existing sites at any time.

To perform a pre-scan check:

1. From the top menu, select Sites > All sites.
2. Select the site that you want to perform a pre-scan check for.
3. In the Pre-scan check menu at the top of the main pane, click Run pre-scan check.

The pre-scan check runs the URL connection check, and attempts to run your recorded login sequences where applicable. The pre-scan check captures still images from the recorded login sequences for you to review.

When the pre-scan check is complete, you can review the connection check for your URLs. Expand the Pre-scan check menu and go to the Connection checks tab to see the connection status of your target URLs. You'll see some remedial advice if the connection check fails.

Managing recorded logins

If you have any recorded login sequences for the site, you'll see the Recorded logins tab. This enables you to review and edit your recorded logins. For more information about reviewing recorded logins, see Reviewing a recorded login sequence.

To edit a recorded login:

1. Click the pencil icon next to the recorded login sequence you want to modify.
2. In the Edit recorded login dialog, update the JSON-based script that contains the recorded actions if necessary. You can also change the label for the recorded login.
3. Click Next.
4. Modify the URL and confirmation text used to verify the authentication status during scans.
5. Click Save.
