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.

Securing Kubernetes and APIs

Kubernetes is one of the most used platforms to deploy cloud applications. Due to its popularity, it is important that you understand the basics of securing Kubernetes to enhance the protection of your cloud environment.

Cloud-native security

To better understand how Kubernetes security relates to cloud security, let's look at the following figure, which explains the layered model of the four Cs of cloud-native systems:

Figure 11.6 – The four Cs of cloud-native security

As seen in the preceding figure, this is a layered model based on the Defense in Depth (DiD) model, designed to enhance the security of cloud-based developments.

The first line of defense is the cloud itself (a topic that we just covered), however, there are some specific aspects that you may take into consideration that are related to each cloud provider, so the best practice here is to check the page of your cloud provider to better understand...
