IoT and Edge Computing for Architects - Second Edition

By: Perry Lea

Overview of this book

Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. An architectural guide is needed 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 IoT devices. IoT and Edge Computing for Architects, Second Edition encompasses the entire spectrum of IoT solutions, from IoT sensors to the cloud. It examines modern sensor systems, focusing on their power and functionality. It also looks at communication theory, paying close attention to near-range PAN, including the new Bluetooth® 5.0 specification and mesh networks. Then, the book explores IP-based communication in LAN and WAN, including 802.11ah, 5G LTE cellular, Sigfox, and LoRaWAN. It also explains edge computing, routing and gateways, and their role in fog computing, as well as the messaging protocols of MQTT 5.0 and CoAP. With the data now in internet form, you'll get an understanding of cloud and fog architectures, including the OpenFog standards. The book wraps up the analytics portion with the application of statistical analysis, complex event processing, and deep learning models. The book then concludes by providing a holistic view of IoT security, cryptography, and shell security in addition to software-defined perimeters and blockchains.

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 DoS attack in history, which spawned from insecure IoT devices in remote areas.
  • Stuxnet: A nation-state cyber weapon targeting industrial SCADA IoT devices controlling uranium enrichment centrifuges and causing substantial and irreversible damage to Iran's nuclear program.
  • Chain Reaction: A research method to exploit PAN 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...
