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.

Cybersecurity automation with the Raspberry Pi

In Chapter 10, Applying IoT Security, we covered a lot of cool cybersecurity projects that you can do with the Raspberry Pi, including the following:

  • Detection of a rogue access point
  • Creating an Intrusion Detection System (ISD) and a firewall with the Raspberry Pi
  • Creating a machine to safely copy information from a Universal Serial Bus (USB) device
  • Creating a honeypot
  • Creating a network monitoring device
  • Creating an ad blocker
  • And even creating a system to detect a rogue Raspberry Pi in your network and how to disable it

Now, in this section, we will do an overview of Raspberry Pi projects that will help you to automate some cybersecurity tasks.
