| Popis: | Owing to the increasing threat of malwares and attacks, the defense mechanism design of various attacks becomes an important issue. Currently, there are various kinds of malwares, such as computer viruses, Trojan-horses, spywares, adwares, worms, and zombies, etc. Attacks are like zero-day attack, black-hole attack, Denial of Service attacks, man-in-the-middle attack and so on. The above attacks will be threats to the computer systems. This article focuses on the defense mechanism for Distributed Denial of Service (DDoS) attacks. DDoS attacks use a lot of request packets or garbage packets to occupy network bandwidth and consume performance of the target host. If the attack target is a commercial website, DDoS attacks will cause transmission delay and more seriously they will deny web services. In this paper, we propose a Double Check Priority Queue structure that effectively mitigates the impact of DDoS attacks in order that normal users can still access services. |
