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

AWS ensures data security through a comprehensive approach known as the shared responsibility model. This model emphasizes multiple layers of security that are implemented to protect data in the cloud.

One of the key components of AWS's approach is the use of various security measures, including physical security at data centers, network security, identity and access management, and data encryption. Each of these layers addresses different aspects of security, ensuring that even if one layer is compromised, others are in place to protect the data.

For example, physical security measures protect the facilities where the data is stored, while network security controls help to prevent unauthorized access and attacks. Identity and access management provides a way to define who can access specific resources, and data encryption protects the data itself from being accessed by unauthorized users.

This layered approach greatly enhances the overall security posture of AWS, making it difficult for any one vulnerability to lead to a full compromise of data. Thus, the correct answer highlights the fundamental strategy AWS employs to maintain data security across its services.
