Is there an S3 policy for limiting access to only see/access one bucket?

Question

I have a simple bucket that looks like images.mysite.com on my S3 and other buckets containing backups, etc.

I want to allow a specific user to be able

Answer 1

A nice simple solution we came up with is to block the user to login to the root directory. So they must login with remote path set to desired folder.

 {
"Statement": [
    {
        "Effect": "Allow",
        "Action": "s3:*",
        "Resource": "arn:aws:s3:::folder-name*",
        "Condition": {}
    }
]
}
