A company deployed a web app to Azure and manages user identities, permissions, and multi-factor authentication for app access. Under the Shared Responsibility Model, which customer responsibility does this represent?

Account and Access Management is a customer responsibility under the Shared Responsibility Model. The company is actively managing user identities, permissions, and multi-factor authentication, which directly falls under controlling who can access their applications and resources. Azure provides the tools and services for identity management, but the customer is responsible for configuring and utilizing them to secure their data and applications. Physical Network Security is an Azure responsibility, as they manage the physical infrastructure. The Operating System of the Host is also an Azure responsibility for PaaS and SaaS services, though it can be shared or customer responsibility for IaaS. Virtualization Layer Management is entirely an Azure responsibility, as they manage the underlying hypervisors and virtual infrastructure.
