S3 Bucket Policy - use "Any Authenticated User" or bucket policy?
<p>I've set up an S3 bucket and an IAM user who has full access to the bucket.</p>

<p>Im confused about how to restrict access to the bucket so only this user and cloud front can access it. The cloud front policy was auto generated for me in the cloudfront control pannel.</p>

<p>But as for allowing only my IAM user access, do I:</p>

<ul>
<li><p>Allow "Any Authenticated User", does this refer to my IAM user or to any AWS user in general?</p></li>
<li><p>Or do I need to amend the bucket policy?</p></li>
</ul>
