AWS Certified Data Analytics Specialty 2021 – Hands-On - Encryption 101

The video tutorial explains encryption mechanisms, focusing on encryption in flight using TLS/SSL, server-side encryption at rest, and client-side encryption. It highlights the importance of securing data during transmission and storage, using examples to illustrate how encryption keys are managed and applied in different scenarios.

What is the primary purpose of using TLS or SSL in network communication?

• To allow multiple users to access data simultaneously

• To ensure data is encrypted during transmission

• To increase the speed of data transmission

• To reduce the cost of data storage

Why is server-side encryption at rest important?

• It allows data to be accessed by multiple servers

• It ensures data is stored securely and only decrypted when needed

• It reduces the need for data backups

• It speeds up data retrieval processes

In server-side encryption, what is the role of a data key?

• To allow data to be shared with third parties

• To increase the speed of data transmission

• To encrypt and decrypt data on the server

• To compress data for storage

What distinguishes client-side encryption from server-side encryption?

• Data is shared with multiple servers

• Data is only encrypted during transmission

• Data is stored in plain text on the client side

• Data is encrypted and decrypted on the client side, not the server

Why might a client choose to use client-side encryption?

• To reduce the cost of encryption

• To increase the speed of data processing

• To ensure the server cannot decrypt the data

• To allow the server to manage encryption keys
