13-baseline-sysmon

Healthy baseline for detections/windows/win_proc_create.yml using REAL Sysmon EID 1 telemetry from agent 002.

What was done

  • Powered on Windows 11 VM (IP changed to 192.168.88.4), reconnected agent to manager
  • Enabled logall_json + filebeat archives (ILM disabled) — archives now in wazuh-archives-4.x-*
  • 64 Sysmon EID 1 events confirmed from agent 002
  • Built REST probe probe_rest.sh using OpenSearch API

Probe results (healthy)

Probe Value
LIVENESS active
VOLUME 64
FIELD_POPULATE 100%
LAST_MATCH rule 60642 @ 2026-07-07T06:57:46Z

Blockers

  • purple-loop run has no Windows/SSH path — canary hardcodes stale IP. Cannot get DETECTED verdict without source changes.
  • SwiftOnSecurity Sysmon config filters common shells — none of the rule's target images appear
