  • Add winlog.logon.id field containing all the logon IDs from the event. This makes it possible to find all events related to a logon ID, including when a user changes to a new user.
  • Copy, rather than move, the TargetUser and SubjectUser fields. This leaves the original fields in event_data.
  • For failure events decode the status codes to winlog.logon.failure.status and winlog.logon.failure.sub_status. And decode the FailureReason to winlog.logon.failure.reason (e.g. make %%2313 into a string).
  • Make the processor chain builder accept other processor chains via the Add() method such that one built chain can be re-used by another.

If anyone tries to run this pipeline on the existing 7.2.0 release you will need to change this line to add .Run like

.Add(copyTargetUser.Run)

and do the same for .Add(copySubjectUser) and .Add(renameCommonAuthFields)
