Explanation:
Amazon S3 provides a set of operations to work with the Amazon S3 resources. Managing S3
resource access refers to granting others permissions to work with S3. There are three ways the
root account owner can define access with S3:
S3 ACL: The user can use ACLs to grant basic read/write permissions to other AWS accounts.
S3 Bucket Policy: The policy is used to grant other AWS accounts or IAM users permissions for
the bucket and the objects in it.
User Access Policy: Define an IAM user and assign him the IAM policy which grants him access to
S3.
