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.

Exploiting a vulnerability

Since organizations are quickly adding layers of security to their IT infrastructures and developers have been building software resistant to known threats such as SQL injection, it has become somewhat difficult to attack systems using traditional hacking techniques. This is why hackers are switching to exploiting vulnerabilities in systems to easily breach otherwise secure systems. Vulnerabilities fetch high prices on the black market and this is where many hackers buy what they need.

Hackers have been known to take the time to study the systems used by targets in order to identify any vulnerabilities. For instance, WikiLeaks has often said that the NSA does the same thing, and currently a database of vulnerabilities exists on computing devices, commonly used software systems, and even everyday devices. At times, hackers breach into such agencies, steal these vulnerabilities, and use them to attack systems. The hacking group The Shadow Brokers regularly...
