CloudFront Origin Path

Question

I do have a S3 bucket with 2 directories on top level:

- public
- private

and I want do use CloudFront to serve only a the files of the "public" directory so I've setup the "Origin Path" of my distribution to that folder. It works like expected but I'm wondering if the "private" directory is also distributed (but not reachable due to that specific origin path of the CF distribution)?

I really don't want the private folder to get distributed or be public reachable in any way.

So the question is: does only the stuff under "origin path" gets distributed or the whole S3 bucket?

Best regards
Daniel

Accepted Answer

Assuming that the S3 bucket is private and that an OAI has been created. In the bucket policy, add the prefix "public" to the ARN :

```
"Resource": "arn:aws:s3:::mybucket/public/*"
```
You could also add an explicit deny statement:

```
{
    "Effect": "Deny",
    "Principal": {
        "AWS": "arn:aws:iam::cloudfront:user/CloudFront Origin Access Identity ABCDEFGHIJ1234"
    },
    "Action": "s3:*",
    "Resource": "arn:aws:s3:::mybucket/private/*"
}
```
