The shared responsibility model is a crucial concept to understand when working with cloud platforms like Azure. Microsoft's model segregates the ownership of the platform, operating system, application, identity, and data between the service provider and its customers.

In Azure's shared responsibility model, the physical security of data centers is completely owned by Microsoft, while the remaining security responsibilities above the stack are either shared or completely owned by the customer and/or Microsoft, depending on the resources being used.

As a customer, you own OS-level security, patching, and vulnerability management when deploying VMs in an IaaS model. This means you're responsible for securing your operating system, applying patches, and managing vulnerabilities.

In contrast, Microsoft manages security in PaaS services like WebApps, while you take care of the stack above the OS, including your application, data, identity, etc. It's essential to understand which security aspects are your responsibility to avoid security loopholes.

To help you navigate this, here are some key points to remember:
