Container security is the practice of applying security tools, processes, and policies to protect container-based workloads. However, to be secure, containers must be properly isolated from each other and from the host system itself. What is container security?

Cloud application security is a combination of policies, processes, and controls that aim to reduce the risk of exposing cloud-based applications to compromise or failure from external or internal threats. This process can delay deployments or cause developers to skip security testing completely to meet project deadlines.
