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.

Types and categories of malware analysis

There are a considerable number of tools that can be used for malware analysis, so to better understand them, let's start by describing the three types (actually, two) of malware analysis tools.

Static malware analysis

This type of analysis is based on a review of the code to determine the potential indication of threats. Those indicators can be hashes, IP addresses, code signatures, code patterns, strings, functions, and so on.

The main characteristic of this analysis is that it does not execute the code, and while this is an advantage in terms of resources, the scope is also limited because it will not fully test the impact and actions executed by the malware.

Another downside is that sophisticated malware may include advanced features aimed to bypass this static analysis.

Dynamic malware analysis

This type of testing requires more resources in terms of skilled professionals, but also in terms of technology because...
