Homelab Security and Privacy Hardening: Build a Secure Self-Hosted Infrastructure with Zero Trust Architecture. VPNs, Firewalls, Encryption, Network S (Paperback) (ISBN-13: 9798271587610)

Build a secure self-hosted stack that resists exposure, blocks lateral movement, and recovers fast when things go wrong.

Running services at home is rewarding, but flat networks, guessable defaults, and quick fixes can leave gaps that scanners and malware will find. This practical guide shows how to apply Zero Trust thinking at homelab scale so access is verified, admin planes are gated, and failures are visible and recoverable.

You will design a segmented network that works for real households, put identity in front of control planes, standardise TLS policy, add high-signal detection, and prove that restores work. Every step is concrete and testable, with configs you can adapt to your gear.

• plan VLANs for admin, servers, users, iot, and guest, write default-deny east west rules, and keep casting working with scoped mdns reflection and acls
• run a hardened resolver with dnssec and qname minimisation, block egress dns bypass, and pin browser doh using firefox and chrome enterprise policies
• configure pfsense or opnsense interfaces and rules, add egress filtering, policy routing, geo and bogon strategy, and enforce anti spoofing and rpf on the edge
• enable remote access without exposure using wireguard on the gateway with proper keys peers and routing, or mesh access via tailscale or headscale with device identity
• centralise identity with keycloak, issue short lived tokens, adopt webauthn passkeys for admins, and protect legacy apps through oauth2 proxy or pomerium
• standardise tls with tls 1.3 preference hsts and modern cipher suites, automate acme for public and private names, use a local ca, and enforce mtls for admin planes
• use caddy or traefik forward auth to pass oidc headers so apps inherit strong logins without code changes
• deploy suricata in ids or inline mode with eve json, add zeek protocol logs for dns tls http and mqtt, and build turnkey nsm with security onion from a tap or mirror port
• harden hosts with cis baselines, lock down ssh, and encrypt disks with luks or zfs native encryption with sound key handling
• manage secrets with vault or sops using age keys so infra-as-code stays safe in git
• secure containers with docker or podman hardening, prefer rootless where practical, and sign images with cosign
• generate sboms with syft, scan images with grype, and fail builds on known issues
• run a small kubernetes with k3s on talos, enable pod security admission, and apply default deny networkpolicies
• gain ebpf visibility with cilium and hubble and add runtime enforcement with tetragon
• protect data with zfs snapshots, replication via zfs send and zrepl, and encrypted backups using restic or borg with repository checks
• run disaster recovery drills for bare metal and vms, time your restores, and fix what slows you down
• adopt ipv6 with a clear plan, ula inside and pd outside, apply nptv6 when needed, and lock down lan with ra guard dhcpv6 guard and router preference
• operate with confidence using loki for logs and grafana dashboards, route alerts with prometheus alertmanager, and keep noise under control with paging hygiene
• follow incident playbooks for suricata high severity and zeek notices, collect first hour artefacts, and communicate impact and next steps clearly
• keep quality high with continuous validation synthetic checks and configuration drift alarms that catch regressions early
