Websense Web Security Gateway is a web proxy event source that will send logs to a SIEM.

Before You Begin

Before setting up this event source within InsightIDR, you must configure Websense to send syslog to the InsightIDR collector. You can find instructions here: http://www.websense.com/content/support/library/web/v80/triton_web_help/settings_siem_explain.aspx

Note that when configuring the syslog, select CEF as the log format.

  2. Do one of the following:
    • Search for Websense Web Security Gateway in the event sources search bar.
    • In the Product Type filter, select Web Proxy.
  3. Select the Websense Web Security Gateway event source tile.
  4. Choose your collector and event source. You can also name your event source if you want.
  5. Optionally choose to send unparsed logs.
  6. Choose the timezone that matches the location of your event source logs.
  7. Select a collection method and specify a port and a protocol.
    • Optionally choose to Encrypt the event source if choosing TCP by downloading the Rapid7 Certificate.
  8. Click Save.
