Cybersecurity – Attack and Defense Strategies - Second Edition

By: Yuri Diogenes, Dr. Erdal Ozkaya

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.

Best cyber defense strategies (Blue Team)

The last line of cybersecurity often comes down to the defense systems that an organization has in place. There are two defense strategies that organizations commonly use; defense in depth and defense in breadth.

Defense in depth

Defense in depth, also referred to as layered securing, involves employing stratified defense mechanisms to make it hard for attackers to breach into organizations. Since multiple layers of security are employed, the failure of one level of security to thwart an attack only exposes attackers to another security layer. Due to this redundancy, it becomes complex and expensive for hackers to try and breach into systems. The defense in depth strategy appeals to organizations that believe that no single layer of security is immune to attacks. Therefore, a series of defense systems is always deployed to protect systems, networks, and data. For instance, an organization that wishes to protect its file server might deploy...
