Hands-On Edge Analytics with Azure IoT

By: Colin Dow

Overview of this book

Edge analytics has gained attention as the IoT model for connected devices rises in popularity. This guide will give you insights into edge analytics as a data analysis model, and help you understand why it’s gaining momentum. You'll begin with the key concepts and components used in an edge analytics app. Moving ahead, you'll delve into communication protocols to understand how sensors send their data to computers or microcontrollers. Next, the book will demonstrate how to design modern edge analytics apps that take advantage of the processing power of modern single-board computers and microcontrollers. Later, you'll explore Microsoft Azure IoT Edge, MicroPython, and the OpenCV visual recognition library. As you progress, you'll cover techniques for processing AI functionalities from the server side to the sensory side of IoT. You'll even get hands-on with designing a smart doorbell system using the technologies you’ve learned. To remove vulnerabilities in the overall edge analytics architecture, you'll discover ways to overcome security and privacy challenges. Finally, you'll use tools to audit and perform real-time monitoring of incoming data and generate alerts for the infrastructure. By the end of this book, you'll have learned how to use edge analytics programming techniques and be able to implement automated analytical computations.

An overview of the Internet-of-Things security

Starting in September 2016, the Mirai botnet launched a distributed denial of service (DDoS) attack using the Internet of Things (IoT) devices on some of the biggest websites in the world, including Reddit, Airbnb, and Netflix. Flooding the DNS provider of these websites with more than 1 TB of data per second from captured devices, the cyber attack was one of the biggest DDoS attacks ever recorded.

So, what exactly is a DDoS attack and how are IoT devices involved? The following diagram shows what a DDoS attack with IoT devices might look like:

DDoS is an attack on a website that overwhelms it with excessive traffic, causing the website to fail. This type of attack is beneficial to the website's competitors. In the case of the Mirai botnet, the attack was designed by students interested in disabling competing Minecraft servers...
