AWS Certified SysOps Administrator Practice Exam

What encryption method does AWS Storage Gateway use for data transfer between the gateway appliance and AWS storage services?

1. Only client-side encryption is used.

2. Data is encrypted with Amazon S3-Managed Encryption Keys.

3. No encryption is applied for data in-transit.

4. Storage Gateway uses SSL/TLS for data encryption during transfer.

The correct answer is: Storage Gateway uses SSL/TLS for data encryption during transfer.

The correct answer is that Storage Gateway uses SSL/TLS for data encryption during transfer. This method ensures that data sent between the gateway appliance and AWS storage services is securely transmitted over the network. SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are protocols designed to provide a secure communication channel over a computer network, and they protect data by encrypting it during transmission, thereby preventing unauthorized access. Using SSL/TLS helps to safeguard sensitive information and maintain confidentiality during the data transfer process, which is especially crucial when dealing with potentially sensitive data. It ensures that the information is not easily intercepted or tampered with by malicious entities while in transit. It is important to understand that SSL/TLS operates at the transport layer and is distinct from other encryption methods such as client-side encryption or server-side encryption. These alternatives focus on different stages or aspects of data management rather than the transport layer, where SSL/TLS is specifically utilized to protect data during its transfer to and from the storage services.
