Cloud security combines technologies, policies, protocols, controls, best practices, and services that secure the cloud platform's data, applications, and infrastructure.
Cloud Security is in a shared responsibility model, which means your security team maintains some responsibilities for security as you move applications, data, and workloads to the cloud. At the same time, the provider takes some responsibility, but not all. Defining the line between your responsibilities and those of your providers is imperative for reducing the risk of introducing vulnerabilities into your public, hybrid, and multi-cloud environments.
