Overview of this book

Cybersecurity – Attack and Defense Strategies, Second Edition is a completely revised new edition of the bestselling book, covering the very latest security threats and defense mechanisms including a detailed overview of Cloud Security Posture Management (CSPM) and an assessment of the current threat landscape, with additional focus on new IoT threats and cryptomining. Cybersecurity starts with the basics that organizations need to know to maintain a secure posture against outside threat and design a robust cybersecurity program. It takes you into the mindset of a Threat Actor to help you better understand the motivation and the steps of performing an actual attack – the Cybersecurity kill chain. You will gain hands-on experience in implementing cybersecurity using new techniques in reconnaissance and chasing a user’s identity that will enable you to discover how a system is compromised, and identify and then exploit the vulnerabilities in your own system. This book also focuses on defense strategies to enhance the security of a system. You will also discover in-depth tools, including Azure Sentinel, to ensure there are security controls in each network layer, and how to carry out the recovery process of a compromised system.

A terminology that has been growing substantially over the years is the concept of a zero trust network. The whole idea of this name is to debunk the old mentality that there are "trusted networks". In the past, most network diagrams were created by using a perimeter, the internal network (also known as a trusted network) and the external network (also known as an untrusted network). The zero trust network approach basically means: all networks (internal and external) are not trustable, all networks by nature can be considered a hostile place, where attackers may already reside.

To build a zero trust network you need to assume that threats exist, regardless of the location, and that user's credentials can be compromised, which means that attackers might already be inside of your network. As you can see, a zero trust network is more a concept and approach to network security than a technology per se. Many vendors will advertise their own solution...
