What You Will Learn

A growing trend in recent years has seen small-form factor computing devices increasingly accessing networks to provide connectivity to what typically used to be disconnected devices. While we can debate if your home appliances truly need Internet access, there is no debate that the Internet of Things (IoT) is here to stay. It allows for deeper connectivity of many devices that are indeed useful, with great benefits to homes and enterprises alike.

Unfortunately, with this proliferation of connected technology, many of these devices do not consider or only minimally consider security in the design process. While we have seen this behavior in other types of testing as well, IoT is different because it utilizes and mixes together many different technology stacks such as custom Operating System builds, web and API interfaces, various networking protocols (e.g., Zigbee, LoRA, Bluetooth/BLE, WiFi), and proprietary wireless. This wide range of diverse, poorly secured technology makes for a desirable pivot point into networks, opportunities for modification of user data, network traffic manipulation, and more.

SEC556 will familiarize you with common interfaces in IoT devices and recommend a process along with the Internet of Things Attack (IoTA) testing framework to evaluate these devices within many layers of the Open Systems Interconnection (OSI) model. From firmware and network protocol analysis to hardware implementation issues and all the way to application flaws, we will give you the tools and hands-on techniques to evaluate the ever-expanding range of IoT devices. The course approach facilitates examining the IoT ecosystem across many different verticals, from automotive technology to healthcare, manufacturing, and industrial control systems. In all cases, the methodology is the same but the risk model is different.

Once weve been empowered to understand each individual challenge, we can understand the need for more secure development and implementation practices with IoT devices.

You will be able to:
  • Assess IoT network-facing controls, web applications, and API endpoints with an IoT focus
  • Examine hardware to discover functionality and find interaction points and use them to obtain data from the hardware
  • Uncover firmware from hardware and other means, and explore it for secrets and implementation failures
  • Sniff, interact with, and manipulate WiFi, LoRA, and Zigbee wireless technologies and understand security failures in implementation
  • Interact with Bluetooth Low Energy (BLE) for device manipulation
  • Automate recovery of unknown radio protocols to perform replay attacks and additional analysis
You will receive with this course:
  • BusPirate 3.6a and cable
  • SPI Flash integrated circuit
  • Solderless breadboard
  • HackRF One with antenna
  • HackRF ANT500 antenna
