Overview of this book

Every organization has its own data and digital assets that need to be protected against an ever-growing threat landscape that compromises the availability, integrity, and confidentiality of crucial data. Therefore, it is important to train professionals in the latest defensive security skills and tools to secure them. Mastering Defensive Security provides you with in-depth knowledge of the latest cybersecurity threats along with the best tools and techniques needed to keep your infrastructure secure. The book begins by establishing a strong foundation of cybersecurity concepts and advances to explore the latest security technologies such as Wireshark, Damn Vulnerable Web App (DVWA), Burp Suite, OpenVAS, and Nmap, hardware threats such as a weaponized Raspberry Pi, and hardening techniques for Unix, Windows, web applications, and cloud infrastructures. As you make progress through the chapters, you'll get to grips with several advanced techniques such as malware analysis, security automation, computer forensics, and vulnerability assessment, which will help you to leverage pentesting for security. By the end of this book, you'll have become familiar with creating your own defensive security tools using IoT devices and developed advanced defensive security skills.

Summary

In this chapter, we started by reviewing the different phases of a cyber attack. Then we learned how to use Nmap to check for vulnerabilities in our infrastructure and make the scanning phase of an attack harder for an attacker.

Then we reviewed the most common Wi-Fi vulnerabilities and how to address them. Additionally, we also learned how to create a Wi-Fi user security guide to reduce risks when using a wireless network. This is a great asset that you can leverage to support your network security strategy and educate users.

After that, we moved to a more technical topic and learned how to use Wireshark to find vulnerabilities and even did a couple of labs to see in real time how attackers can capture your data (including passwords) when you use insecure protocols.

And finally, we closed this journey through network security by doing an overview of IDS and IPS, what they are, some examples of them, and a comparison between them for you to better understand the differences...
