Preventing from Denial of Service Attacks by Using Multi- Layer Algorithm

DOS (Denial of Service) attack is one of the most dangerous attacks to servers. This attack causes the server not to be available anymore and make it shut down. This kind of attack is one of the most unavoidable attacks that are done by using different methods such as Botnet, Zombi. This attack occurs by using a strong server or several altogether the aim server. They do their task (attack) by sending some packet by high speed and high volume. This article helps you to stop this attack by using some ideas on the basis of schedule and information volume. In this method, the multi-layer algorithm is proposed to suppress DOS attacks by any layer are performed. Each layer operations arePerformed to suppress DOS attacks.
