Zero-Trust IoT Security with Raspberry Pi:
Design and Build a Secure Smart Home Using Zero-Trust Architecture and Practical Home Lab Techniques
What happens when a single compromised smart bulb can see your laptop, your camera feeds, and your personal files?
Most smart homes are built on a dangerous assumption: if a device is inside your Wi-Fi network, it's safe. But IoT devices are small computers with exposed services, cloud connections, and inconsistent update models. One weak device can quietly become a bridge to everything else.
Zero-Trust IoT Security with Raspberry Pi shows you how to replace implicit trust with enforceable architecture.
This practical guide walks you step by step through designing and building a secure smart home using Zero-Trust principles, network segmentation, and a hardened Raspberry Pi security node. Instead of relying on vendor promises, you'll create clear boundaries between Trusted and IoT zones, apply least-privilege policies with nftables, monitor device behavior, and validate your defenses through structured threat testing.
This is not theory. It's a working home lab.
Inside, you'll learn how to: Inventory and profile every IoT device on your networkAssign stable device identities using DHCP reservations and labelingBuild segmented network zones to prevent lateral movementEnforce firewall policies that allow only required servicesMonitor traffic with tools like nmap and tcpdumpTest your architecture with controlled attack simulationsMaintain and evolve your Zero-Trust home as new devices are addedBy the end, you won't just have a "secure Wi-Fi." You'll have a deliberately engineered environment where devices can only talk to what they must, and where unexpected behavior becomes visible immediately.
Whether you're a home lab enthusiast, a networking professional, or someone who simply wants stronger smart home security, this book equips you with repeatable techniques grounded in real Zero-Trust architecture.
If you care about IoT security, network segmentation, Raspberry Pi firewall implementation, and practical home network protection, this guide gives you the blueprint.
Stop assuming your smart home is safe.
Build one that proves it.
