Create a WAS Scan

Required Additional License: Tenable.io Web Application Scanning

Required Tenable.io Web Application Scanning User Role: Basic, Scan Operator, Standard, Scan Manager, or Administrator

For a demonstration on creating a WAS scan, see the following video:

To create a scan in the new Tenable.io Web Application Scanning interface:

  1. In the upper-left corner, click the Menu button.

    The left navigation plane appears.

  2. In the left navigation plane, in the Web App Scanning section, click Scans.

    The Web Application Scanning Scans page appears.

    Note: If your Tenable.io Web Application Scanning license expires, your web application scans no longer appear in the scans table.

  3. In the upper-right corner of the page, click the add Create Scan button.

    The Select a Scan Template page appears. By default, the Web Application tab is active.

  4. Do one of the following:

    • If you want to save without launching the scan, click Save.

      Tenable.io Web Application Scanning saves the scan.

    • If you want to save and launch the scan immediately, click Save & Launch.

      Tenable.io Web Application Scanning saves and launches the scan.

    Note: Tenable.io limits scan chunks to 10,000 hosts or 150,000 findings. If a scan chunk exceeds either value, Tenable.io does not process the scan and eventually aborts it.

    5. Note: When you launch a scan, the time the scanner takes to complete the scan varies depending on the system load. To prevent unnecessarily lengthy scan times, avoid launching an excessive number of scans simultaneously.

    Excessive numbers of concurrent scans may exhaust the system's scanning capacity. If necessary, Tenable.io Web Application Scanning automatically staggers concurrent scans to ensure consistent scanning performance.

    Note: Tenable.io Web Application Scanning aborts scans that remain in pending status for more than four hours. If Tenable.io Web Application Scanning aborts a scan, modify your scan schedules to reduce the number of overlapping scans. If you still have issues, contact Tenable Support.
