Question

a company is using amazon s3 to store frequently accessed data. the s3 bucket is shared with external users that will upload files regularly. a solutions architect needs to implement a solution that will grant the bucket owner full access to all uploaded objects in the s3 bucket. what action should be done to achieve this task?

Answer 1

To grant the bucket owner full access to uploaded S3 objects, implement a bucket policy that sets s3:x-amz-acl to bucket-owner-control. This ensures the bucket owner has permissions to manage and access all data.

Step-by-step explanation:

To ensure that the company owning the Amazon S3 bucket has full access to all uploaded objects, the solutions architect should implement a bucket policy that includes a clause granting the bucket owner full control. One way to achieve this is by adding the following bucket policy statement:

{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": "*",
"Action": "s3:PutObject",
"Resource": "arn:aws:s3:::bucket-name/*",
"Condition": {
"StringEquals": {
"s3:x-amz-acl": "bucket-owner-control"
}
}
}
]
}

By setting the s3:x-amz-acl condition to bucket-owner-control, any objects uploaded by external users automatically grant full control to the bucket owner. This approach ensures that the bucket owner maintains permissions to manage and access the data regardless of who uploads it.
