Explanation
Username is not an available filter on the Hosts Management page. The Hosts Management page allows you to view and manage all the hosts in your environment that have Falcon sensors installed. You can filter the hosts by hostname, group, OS version, sensor version, last seen date, health events, detections, and preventions. You can also perform actions such as assigning hosts to groups, updating sensor policies, uninstalling sensors, or isolating hosts1.

Explanation
The report that can be used to determine if Script Based Execution Monitoring (SBEM) is not enabled on a Falcon host due to an old prevention policy is Prevention Policy Debug. The Prevention Policy Debug report allows you to view and compare the prevention policy settings applied to each host in your environment. You can use this report to identify any hosts that have outdated or inconsistent prevention policy settings, such as SBEM, which is a feature that monitors and prevents malicious script execution on Windows systems1.

Explanation
The only place where create host groups is in " Host and setup management > host Groups> Create a group" In Sensor Update policies you can only asign a group of host to the policy not creating a group of hosts.

Explanation
The CID (Customer ID) is located at Hosts setup and management > Deploy > Sensor Downloads and is listed along with the checksum. The CID is a unique identifier for your organization that is required for authenticating your sensor installation and communication with the Falcon cloud. The checksum is a value that verifies the integrity of the sensor download file. You can find your CID and checksum at the top of the Sensor Downloads page1.

Explanation
The place where you can find the history of the successes and failures for any Falcon Fusion workflows is the Workflow Execution log. The Workflow Execution log in the Workflow Management option allows you to view the status and results of workflow executions triggered by detection events. You can filter the log by workflow name, status, start and end time, and detection ID. You can also view the details of each execution, including the actions performed, the output received, and any errors encountered. This log can help you troubleshoot potential failures or issues with your workflows1.
