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.

Detection capabilities

Since the current threat landscape is very dynamic and it changes rapidly, it requires detection systems that can quickly adjust to new attacks. The traditional detection systems that rely in manual fine-tuning of initial rules, fixed thresholds, and fixed baselines will most likely trigger too many false positives, and that's not sustainable for many organizations nowadays. When preparing to defend against attackers, the Blue Team must leverage a series of techniques that include:

  • Data correlation from multiple data sources
  • Profiling
  • Behavior analytics
  • Anomaly detection
  • Activity evaluation
  • Machine learning

It is important to emphasize that some of the traditional security controls, such as protocol analysis and signature-based anti-malware, still have their place in the line of defense, but primarily to combat legacy threats. You shouldn't uninstall your anti-malware software just because it doesn't have any...
