# Performing IoT Security Assessment ## When to Use - Evaluating the security of IoT devices before deployment in enterprise or critical infrastructure environments - Assessing consumer IoT products for security vulnerabilities as part of product security review or certification - Testing industrial IoT (IIoT) devices for vulnerabilities that could affect operational technology environments - Analyzing firmware for backdoors, hardcoded credentials, and known vulnerabilities in embedded components - Evaluating the security of the complete IoT ecosystem including device, cloud backend, and mobile companion app **Do not use** against IoT devices without written authorization, for modifying firmware on devices you do not own, or against medical devices or safety-critical systems without specific medical device testing authorization and safety protocols. ## Prerequisites - Physical access to the target IoT device(s) for hardware analysis and testing - Hardware tools: USB-to-UART adapter (FTDI), Bus Pirate, logic analyzer, JTAG debugger (Segger J-Link), SPI flash programmer (CH341A) - Firmware analysis tools: Binwalk, Firmwalker, Firmware Analysis Toolkit (FAT), Ghidra, QEMU for emulation - Network analysis: Wireshark, tcpdump, Bluetooth tools (Ubertooth, nRF Connect), Zigbee tools (KillerBee) - Soldering equipment for accessing hardware debug points if needed ## Workflow ### Step 1: Device Reconnaissance and Hardware Analysis Examine the physical device and identify attack...
