Final answer:
Objects in File gateways are encrypted at rest, and data transfers from on-premise to Amazon S3 are secure with encryption in transit.
Step-by-step explanation:
Objects encrypted in File gateways are typically encrypted at rest. This means that the data is secured while it is stored on the gateway devices. Encryption at rest helps protect the data from unauthorized access in case the physical devices are compromised.
Data transfers from on-premise to Amazon S3 are secure through encryption in transit. This means that the data is encrypted while it is being transferred between the on-premise environment and Amazon S3. Encryption in transit helps prevent interception or tampering of data during transmission.
