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.

Dealing with vulnerabilities

As we saw in Chapter 2, Managing Threats, Vulnerabilities, and Risks, there is a process to manage vulnerabilities at the company level that includes identification, analysis, assessment, and remediation.

Now, that process is what we called the management side of the story. Now, it's time to understand how that is achieved from the operational (day-to-day) point of view.

Who should be looking for vulnerabilities?

If you have a large enough budget, you must assign this task to either internal or external (third-party) Red Teams (as explained in Chapter 1, A Refresher to Defensive Security Concepts).

On the other hand, if your budget is limited, you can encourage people within your company to report any vulnerability on your infrastructure. To make this effective, you must establish and communicate a process for that purpose and, when possible, provide incentives to the people that find and report those vulnerabilities.
