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.

Cybersecurity vernacular

Cybersecurity has an associated set of definitions describing different types of attacks and provisions. This section briefly covers the jargon of the industry as presented in the rest of this chapter.

Attack and threat terms

The following are the terms and definitions of different attacks or malevolent cyber threats:

  • Amplification attack: Magnifies the bandwidth sent to a victim. Often an attacker will use a legitimate service such as NTP, Steam, or DNS to reflect the attack upon a victim. NTP can amplify 556x, and DNS amplification can escalate the bandwidth by 179x.
  • ARP spoof: A type of attack that sends a falsified ARP message resulting in linking the attacker's MAC address with the IP of a legitimate system.
  • Banner scans: A technique typically used to take inventory of systems on a network that can also be used by an attacker to gain information about a potential attack target by performing HTTP requests...
