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 workflows.

User permissions are set in Falcon by assigning pre-defined permissions to sets called roles.
Users can be assigned multiple roles based on job function and they assume a cumulative set of permissions based on those assignments. Roles are collections of permissions that define what users can see and do in Falcon. Permissions are granular actions that allow users to access specific features or functions in Falcon. For example, a user who is assigned both the Falcon Administrator role and the Falcon Investigator role will have all the permissions from both roles.

It is important to know your company's event data retention limits in the Falcon platform because you will not be able to search event data into the past beyond your retention period. The retention period is the amount of time that event data is stored in the Falcon Cloud, and it may vary depending on your subscription plan and settings. The other options are either incorrect or not related to knowing your retention limits.
