Internet of Things for Architects

By: Perry Lea

Overview of this book

The Internet of Things (IoT) is the fastest growing technology market. Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. An architectural guide is necessary if you want to traverse the spectrum of technologies needed to build a successful IoT system, whether that's a single device or millions of devices. This book encompasses the entire spectrum of IoT solutions, from sensors to the cloud. We start by examining modern sensor systems and focus on their power and functionality. After that, we dive deep into communication theory, paying close attention to near-range PAN, including the new Bluetooth® 5.0 specification and mesh networks. Then, we explore IP-based communication in LAN and WAN, including 802.11ah, 5G LTE cellular, Sigfox, and LoRaWAN. Next, we cover edge routing and gateways and their role in fog computing, as well as the messaging protocols of MQTT and CoAP. With the data now in internet form, you'll get an understanding of cloud and fog architectures, including the OpenFog standards. We wrap up the analytics portion of the book with the application of statistical analysis, complex event processing, and deep learning models. Finally, we conclude by providing a holistic view of the IoT security stack and the anatomical details of IoT exploits while countering them with software defined perimeters and blockchains.

The IoT Story

Anatomy of IoT cyber attacks


The area of cybersecurity is a broad and massive topic beyond the scope of this chapter. However, it is useful to understand three types of IoT-based attacks and exploits. Since the topology of the IoT consists of hardware, networking, protocols, signals, cloud components, frameworks, operating systems, and everything in-between, we will now detail three forms of prevalent attacks:

  • Mirai: The most damaging denial of service attack in history that spawned from insecure IoT devices in remote areas.
  • Stuxnet: A nation-state cyber weapon targeting industrial SCADA IoT devices controlling substantial and irreversible damage to Iran's nuclear program.
  • Chain Reaction: A research method to exploit PAN area networks using nothing but a lightbulb—no internet needed.

By understanding the behaviors of these threats, the architect can derive preventative technologies and processes to ensure similar events are mitigated.
