Kurzbeschreibung des Verlags

Secure your smart home and IoT network with OpenWrt-without sacrificing usability, automation, or performance.IOT SECURITY WITH OPENWRT is a practical, hands-on guide to building a production-ready smart-home and edge security architecture using OpenWrt 25.12+, VLANs, firewall4, nftables, WireGuard, MQTT, Matter, Thread, Home Assistant, DNS filtering, and zero-trust segmentation.

Instead of placing cameras, smart TVs, voice assistants, sensors, plugs, guests, and trusted computers on one flat network, this book shows you how to separate devices by trust level, restrict unnecessary communication, control internet access, and validate every security boundary with real tools and repeatable tests.

You will learn how to: Deploy and harden OpenWrt 25.12+ as a secure IoT gatewayBuild Management, Trusted, IoT, Camera, Automation, Guest, and Quarantine VLANsConfigure DSA bridges, VLAN tagging, DHCP, IPv4, and IPv6Create dedicated IoT SSIDs with WPA2/WPA3 and wireless isolationBuild least-privilege firewall policies with firewall4 and nftablesSecure MQTT brokers with authentication, ACLs, and controlled cross-VLAN accessEnforce DNS policy and integrate filtering solutions such as AdGuard HomeSecure Home Assistant without exposing the entire automation networkIntegrate Matter, Thread Border Routers, Zigbee, and Z-Wave gatewaysIsolate cameras, smart TVs, speakers, voice assistants, and low-trust appliancesProvide secure remote access with WireGuard instead of dangerous port forwardingDetect DNS bypass, suspicious outbound traffic, and unexpected device behaviorQuarantine compromised or unknown IoT devicesTroubleshoot with logread, nftables counters, tcpdump, Wireshark, Nmap, and conntrackImprove network responsiveness with SQM and CAKE>The book follows a practical WHY → HOW → IMPLEMENT → BREAK IT → FIX IT → VALIDATE IT approach. Every major topic is reinforced with hands-on projects, troubleshooting guidance, validation steps, and a complete end-to-end capstone.In the final project, you will build a portfolio-grade architecture: Internet → OpenWrt → Management → Trusted → IoT → Cameras → Automation → Guests → Quarantine>This book is ideal for: OpenWrt usersSmart-home enthusiastsHome Assistant usersNetwork and security engineersDevOps, SRE, and platform engineersHomelab buildersSMB administrators>If you want to move beyond a basic home router and build a segmented, observable, recoverable, and security-focused IoT network, IOT SECURITY WITH OPENWRT gives you the architecture, tools, and practical workflows to do it properly.
