________________ Pillar of the AWS Well-Architecture Framework focuses on protecting data in transit and data at rest.

The pillar of the AWS Well-Architected Framework that focuses on protecting data in transit and data at rest is known as the Security Pillar.

Explanation:

The Security Pillar encompasses best practices and guidelines to help you manage risks associated with your data in the cloud. It emphasizes the importance of protecting data both while it is being transferred (in transit) and when it is stored (at rest).

In transit, data encryption techniques such as SSL/TLS can be employed to safeguard information traveling over networks. This ensures that data is accessible only by the intended recipients and is protected from eavesdropping or man-in-the-middle attacks. For data at rest, strategies include using encryption protocols like AES to secure stored data, employing access control mechanisms, and maintaining compliance with industry regulations.

To summarize, the Security Pillar is vital for any architecture strategy in AWS as it upholds the confidentiality, integrity, and availability of data, aligning with broader organizational security policies and frameworks.
