Month 2 – Security Foundations & SIEM Integration
Month 2: Hardening, monitoring, and SIEM integration across your homelab.

Overview What you will accomplish

Month 2 focuses on strengthening your environment and building visibility. You’ll apply baseline hardening, configure centralized logging, deploy a lightweight SIEM, and begin tuning alerts and dashboards.

  • Apply domain‑wide baseline security policies.
  • Enable Windows Event Forwarding (WEF) for centralized logs.
  • Deploy a lightweight SIEM and ingest logs from DC01, WIN10‑LAB, and OPNsense.
  • Create dashboards and tune alerts for authentication, system, and network events.
  • Simulate incidents and validate detection workflows.

Labs Week-by-week breakdown

Week 5 – Baseline Hardening & Monitoring Setup

Create and link baseline GPOs, enable audit policy, verify Windows Defender, and configure Windows Event Forwarding between WIN10‑LAB and DC01.

Week 6 – SIEM Deployment & Log Collection

Deploy a lightweight SIEM (Wazuh, Security Onion, or Splunk Free), configure log sources, and validate ingestion from domain controller, client, and firewall.

Week 7 – Alert Tuning & Dashboard Design

Build dashboards for authentication, system, and network events. Tune alert thresholds and reduce noise to create meaningful detections.

Week 8 – Incident Simulation & Response Workflow

Simulate brute‑force logon attempts and policy changes, observe SIEM alerts, and document your incident response workflow and escalation path.
