Device Security

Manage network segments in Device Security to properly learn devices and attributes that use overlapping IP addresses.

Follow these procedures to manage network segments:

Update the Assigned Firewalls

Update the Assigned Firewalls

Navigate to NetworksNetworks and SitesNetwork Segments Configuration.
Click on the name of the network segment that you want to update to bring up the Edit Network Segment dialog box.
In the Firewall field, add or remove firewalls.

You can search by a firewall's serial number and name, or use the drop-down selector. The drop-down selector shows if firewalls are assigned to a network segment or not, including the network segment you're editing. If you select a firewall that is assigned to a different network segment, it's removed from its existing network segment after saving the configuration. There must be at least one firewall assigned to the network segment.
Select Edit to save your changes and close the dialog box.
Select the check box next to the updated network segment and Reset the network segment.
Optional If you moved a firewall from one network segment to another, select the network segment that the firewall was removed from and Reset that network segment.

Update the Site Assignment from Network Segments Configuration

Navigate to NetworksNetworks and SitesNetwork Segments Configuration.
Click on the name of the network segment that you want to update to bring up the Edit Network Segment dialog box.
In the Assigned to Site (optional) field, select or create the new site that you want to assign the network segment to.

Select or creating a new site replaces the existing site assignment in the Assigned to Site (optional) field. A network segment can only be assigned to one site.
Select Edit to save your changes and close the dialog box.
Select the check box next to the updated network segment and Reset the network segment.

Update the Site Assignment from Sites

Navigate to NetworksNetworks and SitesSites.
Edit the site.
1. In the Sites table, find the site that the network segment belongs to.
2. Click the three vertical dots at the far right of the row and select Edit Site to bring up the Edit Site dialog box.
3. In the Network Segment (Optional) field, add or remove network segments assigned to the site.
  
  If you remove a network segment from the site, the network segment is reassigned to the default site after saving the configuration.
  
  If you add a network segment, it is removed from its existing site after saving the configuration.
Save the site configuration.
Navigate to NetworksNetworks and SitesNetwork Segments Configuration.
Select the check boxes next to the network segments that were removed from a site or added to a new site and Reset the network segments.

Delete or Reset Network Segments

Navigate to NetworksNetworks and SitesNetwork Segments Configuration.
Select the check box next to the network segments that you want to delete or reset.
