Network attack using TCP protocol for performing DoS and DDoS attacks

In this article a new modified attack using TCP protocol is described. This attack exploits some principles of SYN attack, which has been widely used in several DoS and DDoS attacks around the world. These attacks focused on both small and huge enterprises. A new modification will be described, which significantly increases overall attack effectivity even if some protecting mechanisms are implemented. In the first part of this article IP and TCP protocols are described in order to explain their role in networks. The following part includes explanation of SYN flooding attack and some basic countermeasures in order to understand necessary details regarding this attack. In the following part a new variant is introduced including some experiments and results.
