Processes and Services is one of the information that is shown in Host Search. Host Search is an Investigate tool that allows you to view events by category, such as process executions, network connections, file writes, etc. Processes and Services is one of the categories that shows information such as process name, command line, parent process name, parent command line, etc. for each process execution event on a host. Quarantined Files, Prevention Policies, and Intel Reports are not shown in Host Search.

Event Search data is recorded with UTC (Coordinated Universal Time) time zone. UTC is a standard time zone that is used as a reference point for other time zones. PST (Pacific Standard Time), GMT (Greenwich Mean Time), and EST (Eastern Standard Time) are not the time zones that Event Search data is recorded with.

This query will return the parent processes responsible for launching badprogram.exe by using a subsearch to find the processrollup2 events where FileName is badprogram.exe, then renaming the TargetProcessld_decimal field to ParentProcessld_decimal and using it as a filter for the main search, then using stats to count the occurrences of each FileName by _time. The other queries will either not return the parent processes or use incorrect field names or syntax.

The OR operator is needed to complete the following query, as it allows to search for events that match any of the specified values. The query would look like this:
event_simpleName=ProcessRollup2 FileName=net.exe OR FileName=ipconfig.exe OR FileName=whoami.exe The OR operator is used to combine multiple search terms or expressions and return events that match at least one of them. The IN, NOT, and AND operators are not suitable for this query, as they have different functions and meanings.
