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.

Using Conditional Access

MFA, the feature we discussed in the previous section, is the perfect option for better protecting your cloud identities. But it is still kind of an on/off decision. Either you activate a user account for MFA, or you don't. Wouldn't it be great to dynamically react to authentication attempts and then decide whether an MFA challenge is needed? With Conditional Access, there is a feature that enables us to define authentication conditions that require more or fewer challenges in the authentication process.

Conditional Access gives customers a broad variety of options to include or exclude in a policy. For example, you could enforce the usage of MFA for specified directory roles, such as Azure AD Global Administrators, and in addition to that, require that the login is performed on a corporate-owned device, or you could exclude your normal Office 365 workers from being challenged by MFA, but only if they are working from a corporate office.
