Access to Amazon S3 bucket

To grant a specific user access to an Amazon S3 bucket, you should add a policy to the IAM User .

Here is a sample IAM policy from User policy examples - Amazon Simple Storage Service :

{
   "Version":"2012-10-17",
   "Statement":[
      {
         "Effect":"Allow",
         "Action": "s3:ListAllMyBuckets",
         "Resource":"*"
      },
      {
         "Effect":"Allow",
         "Action":["s3:ListBucket","s3:GetBucketLocation"],
         "Resource":"arn:aws:s3:::awsexamplebucket1"
      },
      {
         "Effect":"Allow",
         "Action":[
            "s3:PutObject",
            "s3:PutObjectAcl",
            "s3:GetObject",
            "s3:GetObjectAcl",
            "s3:DeleteObject"
         ],
         "Resource":"arn:aws:s3:::awsexamplebucket1/*"
      }
   ]
}

The above policy allows the user to list the names of all buckets, and upload/download to the awsexamplebucket1 bucket.

Access to CloudFront

Anybody can access a CloudFront distribution via HTTP. Access is not restricted via IAM.

If you have private content, you can Serve private content with signed URLs and signed cookies - Amazon CloudFront .

IAM is only used to grant permission to users to manage the distribution (eg change the configuration). It is not used to control access to the content.
