Episode 46 — Defense in Depth and Layered Protection
This episode explores Azure’s defense in depth strategy, a multilayered approach to securing resources against evolving threats. Learners are introduced to the concept that no single security measure is sufficient—protection must span multiple levels including physical, identity, network, application, and data. Azure implements each layer with integrated controls such as Microsoft Entra ID for identity protection, Azure Firewall and Network Security Groups for perimeter defense, and encryption for data security. Understanding these layers is essential for AZ-900 candidates, as the exam often tests comprehension of how Azure structures its holistic security framework.
The episode provides clear examples of how layered protection works in practice. A web application, for instance, may rely on network controls to restrict traffic, authentication policies to validate users, and application gateways to filter malicious requests. The discussion highlights how monitoring and incident response tie all these layers together, providing visibility and rapid mitigation when anomalies occur. Learners come away understanding that defense in depth is not about redundancy—it is about resilience, ensuring that if one layer fails, others continue to protect the environment.
