Sophisticated low-bandwith Attack - Sophisticated low-bandwidth DDoS attacks use less traffic and increase their effectiveness by aiming at a weak point in the victim's system design, that is, the attacker sends traffic consisting of complicated requests to the system. While it requires more sophistication and understanding of the attacked system, a low bandwidth DDoS attack has three major advantages in comparison to a high bandwidth attack: a) lower cost - since it uses less traffic; b) smaller footprint - hence it is harder to detect; and c) ability to hurt systems which are protected by flow control mechanisms.


An example of such attacks is an attack against HTTP servers by requesting pages that are rarely requested (forcing the server to search in the disk). Similar attacks can be conducted on search engines or on database servers by sending difficult queries that force them to spend much CPU time or disk access time. In fact, an example of such a sophisticated attack can be seen even in the classic SYN attack which aims hurting the TCP stack mechanism at its weakest point, the three-way- handshake process and its corresponding queue.
