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.

IoT security best practices

Security for IoT needs to be considered from the start of design and not retrofitted at the end of a program or in the field. At that point, it is too late. Security also needs to be viewed holistically from the hardware to the cloud. This section illustrates a simple IoT project from the sensor to the cloud and illustrates the "blanket" of security to consider. The intent is to deploy a system with various levels of safeguards, all there to increase the attacker's work function.

Holistic security

Narrowly focusing on one segment of IoT doesn't provide security and establishes a weak link in the security chain. One needs to establish security from the sensor to the cloud and back—a holistic approach. Each component in the chain of control and data should have a checklist of security parameters and enablers. The following diagram illustrates an example of the layers of security from the sensor to the cloud to consider...
