Mastering Defensive Security

By: Cesar Bravo

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.

Creating cybersecurity hardware using IoT-enabled devices

Raspberry Pi is one of the most famous IoT devices used today to create prototypes.

In fact, there are hundreds of cool projects on the internet that you can create with this powerful device.

As seen in Figure 10.9, Raspberry Pi is a very powerful device with a lot of computing power, packed with all the ports that you need, plus some I/O pins to easily connect a plurality of modules and sensors.

There are two main versions: the normal Raspberry Pi (currently at version 4), and Raspberry Pi Zero. This is a miniature version of Raspberry Pi that is portable and consumes very little power. This could be great for some projects:
