Applied Network Security

By: Arthur Salmon, Michael McLafferty, Warun Levesque

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.

Sniffing the Network

In this chapter, we will focus on the various tools and methods used to monitor network traffic. The objective for this chapter is to help the reader gain an understanding of Nmap, Wireshark, and the importance of monitoring a network for potential attacks. This chapter will provide the most common commands used in Nmap. We will provide screenshots and demonstrate how to use the syntax. In this chapter, we will mostly focus on two main network monitoring tools. We will discuss Nmap first because it is a command-line-based tool. Nmap also has a GUI-based version, known as Zenmap. There are advantages to developing your skill with command-line-based tools. They will allow you to gain a better understanding of how the tools function and allow you more flexibility, dependability, and control. GUI-based monitoring tools such as Wireshark also have advantages; we will discuss this in this chapter...
