The present disclosure provides a computer-implemented method, computer system and computer program product for data protection. According to the method, a first container may be created before an application container is ready for running. The first container is configured to: receive a first key from a key management device; obtain first encrypted data for the application container from a storage device; decrypt the first encrypted data using the first key to obtain first decrypted data; and mount the first decrypted data into the application container. The first container may be exited, and then the application container may be switched to ready for running.

Data protection implemented by container lifecycle hooks
