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 offensive security?

Due to the rapid rise in cybercrime, network security has been evolving. More companies are starting to realize that if you want to stop a hacker you must think like a hacker. This mindset has created a new way of protecting networks, by approaching cyber security from a different perspective. Offensive security can best be described as taking proactive measures to neutralize and hunt down threats to a network. According to www.techtarget.com, "offensive security measures are focused on seeking out the perpetrators and in some cases attempting to disable or at least disrupt their operations." Practicing offensive security involves, gathering cyber threat intelligence, using port scanning tools, deploying honeypots, setting up intrusion detection systems, applying network sniffers, and using threat-hunting platforms.

Offensive security also requires the study of the tools hackers...
