A statement within a policy that allows or disallows access to a particular resource. You can state any permission like this: "A has permission to do B to C where D applies." For example, Jane (A) has permission to read messages (B) from John's Amazon SQS queue (C), as long as she asks to receive only a maximum of 10 messages from the queue at a time (D). Whenever Jane sends a request to Amazon SQS to use John's queue, the service checks to see if she has permission and if the request satisfies the conditions John set forth in the permission.
