User Identification Service | The Forcepoint User ID Service and Integrated User ID Service provide user, group, and IP address information that can be used in transparent user identification. The Integrated User ID Service is primarily meant for demonstration purposes and proof-of-concept testing of user identification services. Select — Allows you to select an existing Forcepoint User ID Service or Integrated User ID Service element. None — Disables transparent user identification. Note: For Forcepoint Network Security Platform version 6.4 or higher, we recommend that you use the Forcepoint User ID Service.
Network Filters section (When a Forcepoint User ID Service element is selected)
IP Ranges (Optional) | To prevent the Security Engine from receiving too many logon events, specify the IP address ranges of networks from which to receive logon events. Click Add to add an element to the list, or Remove to remove the selected element. We recommend adding the IP address ranges of networks for which the Security Engine routes traffic. Note: Network filters do not exclude other IP addresses outside of the specified IP address range if a user has at least one logon in the specified IP address range. The Security Engine might still receive logon events from other IP address ranges.
