Remarks
Each bucket and object in Amazon S3 has an ACL that defines its access control policy. When a request is made, Amazon S3 authenticates the request using its standard authentication procedure and then checks the ACL to verify the sender was granted access to the bucket or object. If the sender is approved, the request proceeds. Otherwise, Amazon S3 returns an error.
An ACL is a list of grants. A grant consists of one grantee and one permission. ACLs only grant permissions; they do not deny them.
For convenience, some commonly used Access Control Lists are defined in S3CannedACL.
Note: BucketName and object ACLs are completely independent; an object does not inherit the ACL from its bucket. For example, if you create a bucket and grant write access to another user, you will not be able to access the user's objects unless the user explicitly grants access. This also applies if you grant anonymous write access to a bucket. Only the user "anonymous" will be able to access objects the user created unless permission is explicitly granted to the bucket owner.
Important: We highly recommend that you do not grant the anonymous group write access to your buckets as you will have no control over the objects others can store and their associated charges. For more information, see Grantees and Permissions
