AWS Technical Essentials 2025 – 400 Free Practice Questions to Pass the Exam

The correct approach to data protection under the AWS Shared Responsibility Model emphasizes that while AWS manages the security of the cloud infrastructure, security in the cloud is the responsibility of the user. Encryption is a crucial aspect of this responsibility because it safeguards data both at rest and in transit. By leveraging encryption, users can ensure that their data is encoded and can only be accessed by authorized individuals or systems, thus maintaining data confidentiality and integrity.

Encryption aligns with the user’s responsibility in the model because it requires active participation in implementing the appropriate measures to protect their information. This involves selecting appropriate encryption technologies and managing keys effectively. While AWS may provide tools and services to facilitate encryption, the ultimate responsibility for ensuring that data is properly encrypted lies with the user.

The other options, such as decryption, authentication, and authorization, while essential elements of a comprehensive security strategy, are not positioned within the framework of the AWS Shared Responsibility Model as direct user responsibilities for data protection. Decryption relates to the process of accessing encrypted data and may fall under the user’s scope depending on their implementation strategy. Authentication concerns verifying user identity, and authorization deals with granting permissions, both of which are vital to security but do not specifically pertain to data protection in the same manner that encryption does.
