- Network segmentation — VLANs via OPNsense to isolate IoT, lab services, and management traffic. Default-deny between zones.
- Storage integrity — ZFS on TrueNAS with ECC RAM, automated scrubs, encrypted datasets, and the 3-2-1 backup rule.
- Access control — WireGuard or Tailscale for remote access. Authelia or Keycloak for SSO. No services exposed without authentication.
- Intrusion detection — Wazuh 4.x agents on every host, Suricata on the firewall, CrowdSec for crowdsourced IP reputation blocking.
- Power protection — UPS with NUT or apcupsd for automated graceful shutdown. Prevents ZFS corruption from power loss.
Learning Path
Build your homelab security from the ground up with this progression:
Foundation
- Choose the right drives (CMR HDDs, NVMe for SLOG) and UPS for your build
- Install TrueNAS SCALE 24.10 with encrypted ZFS pools and automated snapshots
- Set up your first Docker containers with non-root users and read-only filesystems
- Configure automated backups with the 3-2-1 strategy and off-site replication
Network Security
- Deploy OPNsense as your firewall with VLAN segmentation for IoT, lab, and management
- Configure Suricata IDS/IPS rules on the firewall for real-time threat detection
- Set up Traefik or Nginx Proxy Manager with automatic Let’s Encrypt TLS certificates
- Implement DNS-level blocking with Pi-hole or AdGuard Home
Service Hardening
- Deploy Wazuh 4.x for centralized log analysis and file integrity monitoring
- Add Authelia for multi-factor authentication in front of all web services
- Harden SSH: key-only auth, fail2ban, and YubiKey FIDO2 resident keys
- Run WireGuard or Tailscale for encrypted remote access with split tunneling
Advanced Operations
- Build dashboards with Grafana and Prometheus for real-time resource and security monitoring
- Self-host AI inference with Ollama for local LLM workloads without cloud dependency
- Deploy CrowdSec for community-driven threat intelligence and automated IP blocking
- Implement Proxmox or Kubernetes for workload orchestration across multiple nodes
Why This Guide Exists
I run a homelab built on TrueNAS SCALE with 96 TB of ZFS storage, OPNsense firewalling, and over twenty self-hosted services. Every guide in this collection comes from something I actually configured, broke, debugged, and fixed in my own environment. Homelabs are uniquely vulnerable: they sit on residential networks, they run 24/7, and most homelab operators do not have a security team reviewing their configurations. One exposed service or one unpatched container can turn your learning environment into an attacker’s foothold.
This guide is for engineers, sysadmins, and tech enthusiasts who want to run self-hosted infrastructure without compromising on security. You do not need enterprise budgets — just discipline and the right architecture. Whether you are setting up your first NAS or expanding to a multi-node cluster with proper monitoring, the articles below cover every layer of the stack.
Building a homelab is one of the most rewarding investments in your tech career. But without proper security, your homelab becomes a liability instead of an asset. This comprehensive guide brings together everything you need to know — from choosing the right hardware and storage to implementing enterprise-grade security with zero trust architecture.
Whether you’re running TrueNAS, Docker, or Kubernetes at home, each guide below dives deep into a specific aspect of homelab security. Start anywhere, or read them all for the complete picture.
