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.
