Cloud Security and the Shared Responsibility Model

This lesson introduces cloud security as a practical operating discipline, not just a set of tools. You will learn how cloud risk differs from traditional data center risk and why identity, configuration, automation, visibility, and governance matter from the first day of a cloud environment.

The core focus is the shared responsibility model: what the cloud provider secures, what the customer secures, and how responsibilities shift across IaaS, PaaS, SaaS, and managed services. By the end, you should be able to explain ownership boundaries, spot common misunderstandings, and use the model to guide security decisions.
