Which field in a DNS Request event points to the responsible process?

In the CrowdStrike Falcon event schema, the ContextProcessIddecimal field contains the Process ID (PID) of the process that performed the action described by the event. For a DnsRequest event, this field identifies the specific process that initiated the DNS query. The decimal suffix indicates the value is the integer-based PID, which can be used to correlate with other events involving the same process on that host. This field is crucial for tracing network activity back to its source process on an endpoint.

A. ContextProcessIdreadable is not a standard field; process identity is typically conveyed through ID, name, and path fields, not a "readable" ID.

B. TargetProcessIddecimal refers to a process being acted upon (e.g., in a process injection event), which is not applicable to a DNS request.

D. ParentProcessIddecimal identifies the parent of the responsible process, not the process that directly initiated the DNS request itself.
