The Events Data Dictionary found in the Falcon documentation is useful for writing hunting queries because it provides a reference of information about the events found in the Investigate > Event Search page of the Falcon Console. The Events Data Dictionary describes each event type, field name, data type, description, and example value that can be used to query and analyze event data. The Streaming API Event Dictionary, Hunting and Investigation, and Event stream APIs are not documentation that provide details about key data fields and sensor events.

Discovering internet-facing servers is an example of actor actions during the RECONNAISSANCE phase of the Cyber Kill Chain.

This is the correct answer for the same reason as above. The Events Data Dictionary provides a reference of information about the events found in the Investigate > Event Search page of the Falcon Console, which is useful for writing hunting queries.

In the Powershell Hunt report, the score signifies a cumulative score of the various potential command line switches that were used in the PowerShell script execution. The score is based on a weighted system that assigns different values to different switches based on their potential maliciousness or usefulness for threat hunting. For example, -EncodedCommand has a higher value than -NoProfile. The score does not signify the number of hosts that ran the PowerShell script, how recently the PowerShell script executed, or the maliciousness score determined by NGAV.

This is the correct answer for the same reason as above. The Hunting and Investigation guide provides sample hunting queries, select walkthroughs, and best practices for hunting with Falcon. It does not provide a detailed tutorial on writing advanced queries, a detailed summary of event names and descriptions, or recommended platform configurations and prevention settings.
