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.

Lab 2

Another tool used for network scanning is Sparta. The following lab demonstrates how this tool works. For this lab, we are using Kali Linux running in VMware.

Sparta is built into Kali 2.0, but if you don't have it, you can get it from the Kali repository by typing kali > apt-get install Sparta:

  1. To get started, open a terminal window and type sparta. The following screenshot demonstrates the first screen you will see:
  1. When you click on it, a GUI resembling the following will open:
  1. Once Sparta has started, we need to add some hosts. If we click on the space that says Click here to add host(s) to scope, it opens a window where we can add IP addresses or the range of IP addresses we want to scan. We are also able to use CIDR notation to indicate an entire subnet, such as 192.168.181.0/24:
  1. After adding our IP host range in the window, click Add to scope. Sparta will start scanning your hosts...
