Overview of this book

In our modern, internet-connected world, where billions of devices constantly collect and send data to systems to be stored and processed, it’s surprising how the intricacies of data transmission and storage are often overlooked in the IoT domain. With Arduino Data Communications, you'll bridge the knowledge gap and become an expert in collecting data from IoT sensors, transmitting data, and configuring your own databases. This book is an exploration of IoT’s inner workings, guiding you through the process of setting up an end-to-end system that you can employ to prototype your own IoT solutions, using easy-to-follow examples. It begins with a general overview of the Arduino ecosystem, acquainting you with various sensors and shields and unveiling the art of data collection. You’ll then explore data formats and methods to store data, both locally and on database servers. As you progress through the chapters, you’ll learn how to set up REST and MQTT infrastructure to communicate with databases and get hands-on with LoRaWAN, Ethernet, cellular, HC-12, and RS-485. The final chapters are your training ground for real-world projects, imparting the essential knowledge you need to tackle complex challenges with confidence. By the end of this Arduino book, you'll have seamlessly configured an end-to-end system, all while immersing yourself in practical scenarios that bring the world of IoT to life.

Enforcing edge security

Your edge devices are computers. A lot of the things that apply to VMs apply to the computers that you will be setting up and deploying. However, you will not have the support of the cloud providers when you set up your edge devices, so you need to take care of everything yourself.

Operating system

The choice of the operating system that you install on your edge device is critical. You will want to avoid bleeding-edge and beta software. If possible, go for long-term support (LTS) variants of any operating system. Also, consider operating systems that will only run signed software. This will ensure that the computer will not run malicious software. One example of this is Ubuntu Core, which is designed for embedded applications and optimized for security.

Login and access control

Your computer can be accessed physically, so you want to ensure that bad actors can’t brute-force their way onto the computer. The way to avoid this is by disabling...
