Overview
This progress update covers the next slice of DCP-005 in the ElliottSecurity Enterprise Homelab: hardening the monitoring platform, validating endpoint observability, integrating threat-intelligence enrichment, and establishing known-good snapshot baselines where capacity allows.

What Advanced
Observability and security validation
Time-sync issues that had dropped Windows telemetry were remediated. A domain-joined Windows lab endpoint is now visible in Observability, and Security functionality was validated against the ingested system and Sysmon path.
Monitoring platform hygiene
Administrative access, unused accounts, API key hygiene, credential rotation, and break-glass practices were tightened through the approved secrets process. Auditing was enabled, and a system-log data view now covers Event Viewer and Sysmon-oriented telemetry.
Threat intelligence
An AlienVault OTX threat-intelligence feed was added to enrich monitoring workflows without publishing operational configuration details.
Reliability baseline
Known-good snapshots were completed for critical monitoring and edge systems. Additional snapshot coverage is blocked until Proxmox storage capacity is expanded by at least 1 TB.
Why It Matters
Telemetry that is enrolled but not visible is not a monitoring program. Validated Observability and Security views, platform hygiene, and recoverability for the SIEM and edge firewall make the lab credible for detection engineering.
Capacity planning is now an explicit reliability dependency: snapshot campaigns cannot outrun storage headroom.
What Comes Next
- Expand Proxmox storage by at least 1 TB and resume broader known-good snapshots
- Broaden endpoint telemetry coverage across additional lab systems
- Validate first detections against ingested Sysmon and Event Viewer data
- Continue Group Policy baselines on the established OU model
