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.

Software-Defined Perimeter

Earlier in the book, Chapter 9, Edge Routing and Networking, the concepts of software-defined networks and overlay networks were discussed. Overlay networks and their ability to create microsegments is extremely powerful especially in mass IoT scaling and situations where a DDoS attack can be mitigated. An additional component of software-defined networking is called Software-Defined Perimeter (SDP) and is worth a discussion in terms of the overall security picture.

SDP architecture

An SDP is an approach to network and communication security where no trust model exists. It is based on the Defense Information Systems Agency (DISA)'s black cloud. Black cloud means information is shared on a need-to-know basis. An SDP can mitigate attacks such as DDoS, MITM, zero-day exploits, and server scanning, among others. Along with providing an overlay and micro-segmentation for each attached device, the perimeter creates an invitation-only (identity...
