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.

Hardening database services

Getting access to the databases is probably the most wanted treasure for an attacker.

And this is not just because of the data they can access, but because by getting access to those databases, the attacker may gain access to other systems, create new users, and more.

Now, you have to consider that when talking about databases, we are talking about a huge field in which each system and technology may have its own hardening steps. Therefore, it is better for you to understand agnostic best practices that apply to most databases, as presented here:

  • Basic security settings such as encryption and auditing must always be on.
  • Use advanced tools to monitor, detect, and deny access to data (if possible, look for new solutions that include AI components to enhance the detection of intrusions).
  • Administrative accounts (such as DBA accounts) must use a stronger password criteria (when possible, 60+-character passwords and a password manager).
  • ...
