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.

Active Sensors

Now that your network is segmented, you need to actively monitor to detect suspicious activities and threats, and take actions based on that. Your security posture won't be fully completed if you don't have a good detection system; this means having the right sensors distributed across the network, monitoring the activities. The Blue Team should take advantage of modern detection technologies that create a profile of the user and computer, in order to better understand anomalies and deviations in normal operations. With this information, preventative actions could be taken.

In this chapter, we are going to cover the following topics:

  • Detection capabilities
  • Intrusion detection systems
  • Intrusion prevention systems
  • Behavior analytics on-premises
  • Behavior analytics in a hybrid cloud
