Mastering Azure Security - Second Edition

By: Mustafa Toroman, Tom Janetscheck

Overview of this book

Security is integrated into every cloud, but this makes users put their guard down as they take cloud security for granted. Although the cloud provides higher security, keeping their resources secure is one of the biggest challenges many organizations face as threats are constantly evolving. Microsoft Azure offers a shared responsibility model that can address any challenge with the right approach. Revised to cover product updates up to early 2022, this book will help you explore a variety of services and features from Microsoft Azure that can help you overcome challenges in cloud security. You'll start by learning the most important security concepts in Azure, their implementation, and then advance to understanding how to keep resources secure. The book will guide you through the tools available for monitoring Azure security and enforcing security and governance the right way. You'll also explore tools to detect threats before they can do any real damage and those that use machine learning and AI to analyze your security logs and detect anomalies. By the end of this cloud security book, you'll have understood cybersecurity in the cloud and be able to design secure solutions in Microsoft Azure.

Log Analytics design considerations

You've already learned that Microsoft Defender for Cloud and Microsoft Sentinel rely heavily on Azure Log Analytics. But there are some important considerations to make before you start your security monitoring journey in the cloud.

The three most important paradigms in this context are as follows:

  • Use as few Log Analytics workspaces as possible.
  • Use regional workspaces to avoid Azure bandwidth costs.
  • Use different workspaces for security and performance monitoring

From a technical point of view, it's best to only use a single, central workspace so all the data resides in one place. Having a single workspace, you can easily, efficiently, and quickly correlate your data to get the respective insights. You also only need to take care of a single role-based access control (RBAC) model for this workspace. However, fine-grained RBAC models demand more effort.
