Mastering IOT

By: Colin Dow, 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. We’ll begin our journey with an introduction to Raspberry Pi and quickly jump right into Python programming. We’ll learn all concepts through multiple projects, and then reinforce our learnings by creating an IoT robot car. We’ll examine modern sensor systems and focus on what their power and functionality can bring to our system. We’ll also gain insight into cloud and fog architectures, including the OpenFog standards. The Learning Path will conclude by discussing three forms of prevalent attacks and ways to improve the security of our IoT infrastructure. By the end of this Learning Path, we will have traversed the entire spectrum of technologies needed to build a successful IoT system, and will have the confidence to build, secure, and monitor our IoT infrastructure. This Learning Path includes content from the following Packt products: Internet of Things Programming Projects by Colin Dow Internet of Things for Architects by Perry Lea

Software defined perimeter


Earlier in the book, in Chapter 8, Router and Gateways, the concept of software-defined networks and overlay networks was 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.

Software-Defined Perimeter architecture

A Software-Defined Perimeter (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...
