IoT & Hardware Security Guide

Welcome to the AppSec Atlas guide on IoT & Hardware Security! As physical devices become increasingly connected, securing the Internet of Things (IoT) is a critical domain spanning hardware, firmware, network protocols, and cloud applications.

🌟 Overview

This guide provides a comprehensive deep dive into securing IoT devices and underlying hardware architectures. You will learn about typical IoT architectures, firmware reverse engineering, hardware-level debugging interfaces (UART, JTAG), communication protocols (MQTT, BLE), and essential defenses like Secure Boot and secure Over-The-Air (OTA) updates.

🎯 Learning Objectives

By completing this module, you will be able to:

Understand the 3-layer IoT architecture (Perception, Network, Application) and their unique attack surfaces.
Extract, analyze, and reverse engineer firmware images using tools like binwalk.
Identify vulnerabilities in IoT protocols like MQTT, CoAP, and BLE.
Understand and secure hardware debugging interfaces like UART, JTAG, SPI, and I2C.
Design Secure Boot mechanisms and robust, signed Over-The-Air (OTA) updates.
Identify hardcoded secrets (keys, passwords) within device filesystems.

⚙️ Prerequisites

To get the most out of this guide, we recommend having:

Basic understanding of Linux command-line tools.
Familiarity with networking concepts and basic cryptography (TLS, PKI).
Python programming for interacting with IoT protocols and writing analysis scripts.
Optional: A basic understanding of embedded systems (microcontrollers, flash memory).
