AWS Certified Data Analytics Specialty 2021 – Hands-On - S3 Encryption

The video tutorial covers various encryption methods for Amazon S3 buckets, including server-side encryption with S3 managed keys, KMS, and customer-provided keys, as well as client-side encryption. It also discusses encryption in transit using SSL/TLS, emphasizing the importance of secure data transmission. Each method's specificities, advantages, and potential limitations are explained, providing a comprehensive understanding of when and how to use each encryption type.

Which encryption method uses AWS-managed keys for server-side encryption?

• Client-side encryption

• SSE-S3

• SSE-KMS

• SSE-C

What is a key advantage of using SSE-KMS over SSE-S3?

• Faster encryption process

• No need for API calls

• User control over encryption keys

• Lower cost

What is a potential limitation of using SSE-KMS for high throughput applications?

• API call throttling

• Limited key management options

• Insecure key storage

• Increased latency

What must be used to transmit keys securely when using SSE-C?

• FTP

• HTTPS

• SMTP

• HTTP

In client-side encryption, where does the encryption and decryption process occur?

• On the AWS server

• On the client side

• In the S3 bucket

• In the AWS KMS

What is the primary purpose of encryption in transit?

• To encrypt data at rest

• To secure data during transmission

• To manage encryption keys

• To reduce data size

Which encryption method requires the use of a client library for implementation?

• SSE-KMS

• SSE-S3

• Client-side encryption

• SSE-C
