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.

For example, you may want to only allow your Azure administrators to create Azure resources in the North Europe and West Europe Azure regions, or you may only want to have a certain VM SKU size in one of your Azure subscriptions. In these cases, you can create a policy. Once this policy is created and activated, new and existing resources are evaluated for policy compliance. New resources can be prevented from being created if they are non-compliant and existing resources...
