Overview of this book

Azure Sentinel is a Security Information and Event Management (SIEM) tool developed by Microsoft to integrate cloud security and artificial intelligence (AI). Azure Sentinel not only helps clients identify security issues in their environment, but also uses automation to help resolve these issues. With this book, you’ll implement Azure Sentinel and understand how it can help find security incidents in your environment with integrated artificial intelligence, threat analysis, and built-in and community-driven logic. This book starts with an introduction to Azure Sentinel and Log Analytics. You’ll get to grips with data collection and management, before learning how to create effective Azure Sentinel queries to detect anomalous behaviors and patterns of activity. As you make progress, you’ll understand how to develop solutions that automate the responses required to handle security incidents. Finally, you’ll grasp the latest developments in security, discover techniques to enhance your cloud security architecture, and explore how you can contribute to the security community. By the end of this book, you’ll have learned how to implement Azure Sentinel to fit your needs and be able to protect your environment from cyber threats and other security issues.

Scenario mapping

For the final section of this chapter, we are going to look at an important part of SOC development: scenario mapping. This process is carried out on a regular basis to ensure that tools and procedures are tuned for effective analysis and have the right data flow and that responses are well defined to ensure appropriate actions are taken upon detection of potential and actual threats. To make this an effective exercise, we recommend involving a range of different people with diverse skill sets and viewpoints, both technical and non-technical. You can also involve external consultants with specific skills and experience in threat hunting, defense, and attack techniques.

The following process is provided as a starting point. We encourage you to define your own approach to scenario mapping and improve it each time the exercise is carried out.

Step 1 – Define the new scenarios

In this first step, we articulate one scenario at a time; you may want to use...
