That is really a very generic search. DDoS comes in many forms and a number of existing policies will cover the issue. 
 you appear to be looking for a simple answer to a very complex issue. A search of the forums will provide you with some more answers. Basically you cannot stop DDoS attacks because they come from unknown source/s external to your control. If an attacker saturates your line then there is nothing you can do about it.
