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.

What is an evil twin?

An evil twin is a fake wireless access point set up by an attacker to imitate a real wireless access point. The evil twin looks identical to the real access point, so most users will not notice any difference when signing on. Evil twins are often used to setup MITM attacks against unsuspecting victims. Many hackers will set up cloned versions of real Wi-Fi access points and have the victim log into the fake access point through a cloned landing page. An unauthorized access point not controlled by the network admin is called a rogue access point. After the victim connects to the evil twin, they are redirected to a fake landing page prompting them for credentials. When the victim logs into the landing page, the attacker begins harvesting the victim's username and password. Attackers will also sometimes hide a payload within the Accept terms button on a fake Wi-Fi landing page.
