  SOC Proposal Rules — Appendix A4: Windows / Active Directory
  Simulation profile rule IDs : 100341-100364
  Production profile rule IDs : 110341-110364

  Production rules use specific built-in Wazuh rule SIDs as parents
  to avoid the N×M rule-tree explosion from if_group=windows:
    60105/60122 → event 4625 (auth failure)
    60106       → event 4624 (auth success / logon)
    60109       → events 4720/4722 (account create/enable)
    60113       → events 4728/4732 (group membership change)
    67027       → event 4688 (new process created)
    60103       → event 4794 (DSRM password set)

       Parents are specific built-in Wazuh SIDs (not if_group=windows) to
       avoid N×M rule-tree explosion. Each parent fires for one event ID.
