Hardware-Accelerated Device for Protection Against DoS Attacks

This thesis deals with the development of a firmware for hardware-accelerated device used as a protection against amplification (D)DoS attacks. In the today's world, (D)DoS attacks are very common and cause significant financial damages. Therefore the goal is to create affordable and easy to deploy centralized device that would resolve this issue. To reach this goal, a hardware accelerator is being used for the high-volume data transfer processing through a single commonly used server. Design and implementation of the firmware had been done considering the fact that this device will be used in the networks with 100\,Gbps speed. The whole system had undergone functional verification and its real throughput was verified within the laboratory testing as well. Created device has been already deployed into the CESNET network infrastructure during the time of the writing of this thesis and it has been tested by the network administrators. Based on the received feedback, the development will continue focusing on expanding of the detection of more types of attacks
