The adoption of the Cloud brings many security challenges. Securing identities, data, and workloads while trying to stay on the right side of compliance regulations has become a priority for organizations. Mastering Azure Security is your essential handbook for defending applications and data against a complex threat landscape.

Starting with the fundamentals, this book guides you through Azure security from the ground up. You will begin with core concepts like the shared responsibility model and Zero Trust, then apply these to secure key service layers, such as identity and access with Entra ID, networks with NSGs and Azure Firewall, compute for VMs and containers, and data with encryption and access controls. Furthermore, you will look at security governance, learning to manage your environment at scale using Azure Policy and Azure Landing Zones. Finally, you will learn about posture management with Microsoft Defender for Cloud and detect threats using Microsoft Sentinel.

By the end of this book, readers will gain an understanding of Azure security and develop the practical skills required to design, implement, and maintain a secure and compliant cloud infrastructure. Whether you are trying to nail down compliance, make systems more resilient, or know how to handle the latest threats, this book will give you the skills to make it happen.
