If you don't already know what the TCP three way handshake then here's a simple explanation. When a host device (such as your computer) attempts to communicate with a server with reliable connection because it needs to error check and be capable of reestablishing the connection then likely it will choose the TCP protocol over UDP (which is connectionless). Let's go over some basics for a moment and look into what a successful handshake would look like. First a host, such as your computer, initiaties a TCP connection by providing a TCP SYN packet to the destination host (let's just say it's a file sharing server for this example). After the server receives the TCP SYN it returns to a packet back in response with SYN ACK. Now, once your computer intercept the SYN ACK, it will send out one more packet to establish the connect with the ACK.

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.
