Denial-of-Service (DoS) attacks pose an increasing threat to the network systems in recent years as they are simple to implement, hard to prevent, and difficult to trace. An improved dynamic probabilistic packet marking algorithm named IDPPM is presented, which not only can reduce the marking overhead of routers near the attackers, but also can locate attack source rapidly and accurately. The challenge of weakest node and weakest link is solved with the price of a little more numbers of packets to reconstruct the attack path. Theoretical analysis and NS2 simulation demonstrate the effectiveness of the algorithm.
