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 detect an evil twin?

Now that we have a better understanding of what an evil twin is, we can now discuss how to detect them. One of the best evil twin detection tools is called EvilAP_Defender. This tool helps cyber security teams detect and prevent evil twins from attacking users of the wireless network. When EvilAP_Defender detects an evil twin, a notification is sent to your e-mail. When a rogue access point is discovered EvilAP_Defender can execute a DoS attack on users to prevent them from connecting to the rogue access point. The DoS attacks allows for more time to plan a more calculated response to end the evil twin attack. The DoS attack will only target SSIDs with the same name as the real access point. To detect evil twins, EvilAP_Defender uses specific criteria. EvilAP_Defender will scan for access points with the same BSSID as the real access point. Next, the attributes of both access points will...
