Vulnerability discussion

Disabling isolation on the endpoint is a potential indicator of compromise of insider threat. In production deployments, the ability to disable Bromium isolation is not available to non-privileged users.

Check content

Verify that a syslog destination is configured on the BEC server. 1. From the management console, click on the selection arrow next to "Events". 2. Click on "Destinations". 3. Inspect the list of configured syslog destinations. 4. Verify that the Severity level for the source Isolation Host is minimally set to "Warning". If the Bromium monitoring module installed on the BEC or Bromium vSentry does not generate an event and forward to the events server when anomalies in the operation of the application are discovered, this is a finding.

Fix text

Configure the BEC server to automatically forward events to the desired syslog destination. 1. From the management console, click on the selection arrow next to "Events". 2. Click on "Destinations". 3. Click on "Add Syslog Destination". 4. Configure syslog server parameters and verify that the Severity level for the source Isolation Host is minimally set to "Warning". 5. Click "Save". Additional syslog destinations may be configured for forwarding events to multiple destinations simultaneously.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
