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.

Section 3: Deep Dive into Defensive Security


In this chapter, we covered a lot of very interesting and important topics that you can apply to your defense strategy.

First, we learned how to create a vulnerability assessment, including an overview of the most common types of vulnerabilities to help you create the best assessment. Then, we expanded into one of the core aspects of cyber defense: risk management. Here, we learned how to manage cybersecurity risks, and also looked at one of the most famous frameworks in cybersecurity: the NIST Cybersecurity Framework.

Additionally, as discussed in the previous chapter, availability is one of the core principles in cybersecurity. Therefore, to avoid downtime, we learned how to create a BCP, including a deep dive into its most important components: the BIA and the DRP.

We also learned the details behind one of the most common and dangerous vulnerabilities, that is, the famous (or infamous) USB HID vulnerabilities. Here, we learned about the most common attack vectors...
