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.

Wi-Fi cracking tools

Cracking Wi-Fi usually requires multiple tools or suites. One of the best tool suites available is the aircrack-ng tool suite. This tool suite was designed for conducting wireless network assessments. The tool suite focuses on four different aspects of network security.

The first aspect is monitoring network traffic. Putting your wireless adapter into monitor mode will record all network traffic within range of the adapter's wireless radio. It will then write the data to a text file (pcap file) for other tools to further analyze. The tool used for monitoring is called airmon-ng. This tool is used to put the wireless interface controller into monitor mode. Monitor mode disables filtering at the physical layer of the OSI model. This allows anything the adapter's wireless radio can pick up to be captured. Usually wireless cards only see and receive network traffic intended for them. This...
