Create a Network

Required Tenable.io Vulnerability Management User Role: Scan Manager or Administrator

Create a custom network only if you want to scan targets in separate environments that contain overlapping IP ranges. If your scans do not involve separate environments with overlapping IP ranges, keep all scanners in the Default network.

To create a new network:

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

    The left navigation plane appears.

  2. In the left navigation plane, click Settings.

    The Settings page appears.

  3. Click the Sensors tile.

    The Sensors page appears. By default, the Nessus Scanners tab is active and Linked Scanners is selected in the drop-down box.

  4. In the drop-down box, select Networks.

    The list of networks appears.

  5. Click Add Network.

    The Settings page appears.

  6. Type a name for the network.

  7. (Optional) Type a description for the network.
  8. (Optional) Configure Asset Age Out:

    Note: By default, the Asset Age Out toggle is enabled and the value is set to 180 days. At that point, Tenable.io deletes all asset records and associated vulnerabilities. These cannot be recovered, and the deleted assets no longer count towards your license.

    • To change the number of days after which Tenable.io deletes unseen assets, in the Delete Assets Not Seen in the Last text box, type the number of days.

    • To disable the Asset Age Out toggle, click the toggle.

  9. In the lower-right corner, click Create.

    Tenable.io creates the new network. The Manage Scanners page appears.
