A company has an Amazon S3 bucket that contains sensitive dat a. The data must be encrypted in transit and at rest. The company encrypts the data in the S3 bucket by using an AWS Key Management Service (AWS KMS) key. A developer needs to grant several other AWS accounts the permission to use the S3 GetObject operation to retrieve the data from the S3 bucket.

How can the developer enforce that all requests to retrieve the data provide encryption in transit?

A.
Define a resource-based policy on the S3 bucket to deny access when a request meets the condition "aws:SecureTransport": "false".
Answers
A.
Define a resource-based policy on the S3 bucket to deny access when a request meets the condition "aws:SecureTransport": "false".
B.

Answers
C.

D.
Define a resource-based policy on the KMS key to deny access when a request meets the condition of "aws:SecureTransport": "false".
Answers
D.
Define a resource-based policy on the KMS key to deny access when a request meets the condition of "aws:SecureTransport": "false".
Suggested answer: A

Explanation:

Amazon S3 supports resource-based policies, which are JSON documents that specify the permissions for accessing S3 resources. A resource-based policy can be used to enforce encryption in transit by denying access to requests that do not use HTTPS. The condition key aws:SecureTransport can be used to check if the request was sent using SSL. If the value of this key is false, the request is denied; otherwise, the request is allowed. Reference: How do I use an S3 bucket policy to require requests to use Secure Socket Layer (SSL)?
