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.
Table of Contents (23 chapters)
Section 1: Mastering Defensive Security Concepts
Section 2: Applying Defensive Security
Section 3: Deep Dive into Defensive Security


We did a comprehensive overview of the top 21 types of automated attacks that are currently being used by attackers so that you can do an assessment of your organization to determine which of those attacks are a possible threat to your infrastructure and organization.

But we also learned that we can take advantage of automation, so we reviewed some Python libraries that you can leverage to perform automation in tasks related to forensics, web scraping, and network security.

And before closing the chapter, we learned how to take advantage of the famous Raspberry Pi to create some very cool cybersecurity gadgets that enable us to automate some tasks such as gathering malicious addresses to include in our blacklist and two different methods to test the speed and stability of an internet connection.

I hope this last part inspires you to do some extra testing and research to develop your own cybersecurity gadgets and prototypes like a master!
