Modify a Scanner Group

Required Tenable Vulnerability Management User Role: Scan Manager or Administrator

To modify a scanner group:

1. In the left navigation, click Sensors.

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

2. In the drop-down box, select Scanner Groups.

   The list of existing scanner groups you have permission to use or manage appears.

3. (Optional) Search the table for the group you want to modify. For more information, see Tenable Vulnerability Management Tables.
4. In the scanner group table, do one of the following:
   • In the Actions column of the scanner group you want to modify, click the button.

     The action options appear in the row.

   • Right-click the scanner group you want to modify.

     The action options appear next to your cursor.

5. Click Edit.

   The Edit Scanner Group plane appears.

6. Modify any of the following settings:

   Setting	Action
   Name	Type a new name.
   User and Group Permissions	Configure user permissions for the scanner group.

7. (Optional) In the Targets for Scan Routing box, type a comma-separated list of scan routing targets.

   Targets in the list must be in the supported formats.

   This list specifies the targets that scanners in this scanner group can scan if a scan is configured to use the Auto-Select scanner. For more information, see Example: Scan Routing.

   Note: You can specify up to 10,000 individual scan routing targets for an individual scanner group. For example, 192.168.0.1, example.com, *.example.net, 192.168.0.0/24 specifies four scan routing targets. To condense a scan routing target list, Tenable recommends using wildcard and range formats, instead of individual IP addresses.

8. Click Save.

   If Targets for Scan Routing specifies more than the maximum number of targets, an error message appears. Condense the scan routing targets by using wildcard and range formats instead of individual IP addresses, then try again to save the scanner group.

   In all other cases, Tenable Vulnerability Management updates the scanner group with your changes.

To assign scanners to a scanner group:
