In this chapter, we will discuss the Internet of Things (IoT) and how this emerging technological concept has changed network communication. This chapter will define what the IoT is and how it functions. Next, we will talk about how cyber security has changed because of the IoT. We will then move on to exploring the vulnerabilities of the IoT. We want the readers to be able to understand how botnets are being enhanced tremendously by the IoT. This chapter will also cover how the Mirai botnet has impacted network security. The next topics we will elaborate on are, the IoT's role in home automation, wearable devices, medical equipment, drones, driverless cars, and smart cities. After reading this chapter, the reader will acquire a solid understanding of what the IoT is and how it is changing the world.

Overview of this book
Computer networks are increasing at an exponential rate and the most challenging factor organisations are currently facing is network security. Breaching a network is not considered an ingenious effort anymore, so it is very important to gain expertise in securing your network. The book begins by showing you how to identify malicious network behaviour and improve your wireless security. We will teach you what network sniffing is, the various tools associated with it, and how to scan for vulnerable wireless networks. Then we’ll show you how attackers hide the payloads and bypass the victim’s antivirus. Furthermore, we’ll teach you how to spoof IP / MAC address and perform an SQL injection attack and prevent it on your website. We will create an evil twin and demonstrate how to intercept network traffic. Later, you will get familiar with Shodan and Intrusion Detection and will explore the features and tools associated with it. Toward the end, we cover tools such as Yardstick, Ubertooth, Wifi Pineapple, and Alfa used for wireless penetration testing and auditing. This book will show the tools and platform to ethically hack your own network whether it is for your business or for your personal home Wi-Fi.
