prohibited_software_on_endpoint_filter is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.
How To Implement
To successfully implement this search, you must be ingesting data that records process activity from your hosts to populate the endpoint data model in the processes node. This is typically populated via endpoint detection-and-response product, such as Carbon Black or endpoint data sources, such as Sysmon. The data used for this search is usually generated via logs that report process tracking in your Windows audit settings. In addition, you must also have only the
process_name (not the entire process path) marked as “prohibited” in the Enterprise Security
interesting processes table. To include the process names marked as “prohibited”, which is included with ES Content Updates, run the included search
Add Prohibited Processes to Enterprise Security.
