Explanation
According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the ParentProcessld_decimal field contains the decimal value of the process ID of the parent process that spawned or injected into the target process1. This field can be used to trace the process lineage and identify malicious or suspicious activities1.

Explanation
According to the [CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+], event types are categories of events that are generated by the sensor for various activities, such as process executions, file writes, registry modifications, network connections, etc. There are many valid event types, such as StartOfProcess, ProcessRollup2, DnsRequest, etc. However, EndOfProcess is not a valid event type, as there is no such event that records the end of a process.

Explanation
According to the CrowdStrike Falcon Data Replicator (FDR) Add-on for Splunk Guide, the Full Detection Details tool allows you to view detailed information about a detection, such as detection ID, severity, tactic, technique, description, etc1. You can also view the events generated by the processes involved in the detection in different ways, such as process tree, process timeline, or process activity1. The process tree view provides a graphical representation of the process hierarchy and activity1. You can see children and sibling processes information by expanding or collapsing nodes in the tree1.

Explanation
According to the [Microsoft website], taskeng.exe is a legitimate Windows process that is responsible for running scheduled tasks. However, some malware may use this process or create a fake one to execute malicious code. Therefore, if you notice taskeng.exe involved in a detection, you should investigate whether there are any scheduled tasks registered prior to the detection that may have triggered or injected into taskeng.exe. You can use tools such as schtasks.exe or Task Scheduler to view or manage scheduled tasks.

Explanation
According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Process Activity View allows you to view all events generated by a process involved in a detection in a rows-and-columns style view1. This can be helpful because it creates a consolidated view of all detection events for that process that can be exported for further analysis1. You can also sort, filter, and pivot on the events by various fields, such as event type, timestamp, file name, registry key, network destination, etc1.
