How can AWS S3 Bucket policy be utilized to enable IAM user access to Cloudfront?

edit

To enable IAM user access to CloudFront using AWS S3 bucket policy, follow the steps below:

1. Open the AWS S3 console and select the bucket that contains the objects you want to distribute through CloudFront.

2. On the bucket’s properties page, select “Permissions.”

3. Under “Bucket Policy,” click on “Edit.”

4. To grant CloudFront permission, add the following JSON to the bucket policy document:

{ "Version":"2012-10-17", "Statement":[ { "Effect":"Allow", "Principal":{ "AWS":[ "arn:aws:iam::cloudfront:user/CloudFront Origin Access Identity ABC123" ] }, "Action":"s3:GetObject", "Resource":"arn:aws:s3:::bucket-name/*" } ] }

Note that in the above JSON, replace “bucket-name” with your actual bucket name and “ABC123” with your actual CloudFront origin access identity.

1. Click on “Save Changes.”

2. Make sure that the IAM user accessing CloudFront has permission to access the S3 bucket.

3. Create a CloudFront distribution with the S3 bucket as the origin.

4. Test the access to the CloudFront URL.
