Applied Network Security

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.

How to Crack Wi-Fi Passwords

This chapter will have three main objectives for the reader to learn. The first objective is to create an understanding of the vulnerabilities found within Wi-Fi technology. We will cover the different methods that a hacker might use to gain a victim's Wi-Fi password. The reader will be introduced to new Wi-Fi hacking terminology and definitions. This chapter will have a hands-on lab. This lab will demonstrate the process of cracking a WPA2 Wi-Fi password. We will focus on using the aircrack-ng suite to crack passwords with. There will also be screenshots for each step so that the reader can follow along. The syntax of the aircrack-ng suite will also be explained. To complete the lab in this chapter you will need a router and Kali Linux (use a virtual machine to run Kali Linux. VMware Player is free and has good stability). We have recommended the most compatible Wi-Fi adapters...
