Protection Against DoS Attacks Using P4 Language
Vojanec, Kamil ; Fukač, Tomáš (referee) ; Kučera, Jan (advisor)
This thesis focuses on reimplementation of existing DoS (Denial of Service) attack mitigation device with high-level P4 programming language. The main reason for using P4 is to enhance adaptability and functionality to different types of DoS attacks. The created device is designed in a modular way and enables easy alterations by using interchangeable components. The target platform for this thesis is an FPGA acceleration card. The work results in designing several DoS mitigation components and implementing applications composed of these components. Pats of this work have been presented at IEEE ANCS (Symposium on Architectures for Networking and Communication Systems) in September 2019 at University of Cambridge.

Accelerating an Application for DDoS Mitigation
Vojanec, Kamil ; Kekely, Lukáš (referee) ; Kučera, Jan (advisor)
This thesis focuses on optimizing and accelerating an application used for mitigating Denial of Service attacks. The goal is to analyze the existing implementation of DDoS Protector and to identify components which are suitable for optimization or hardware acceleration. Based on the analysis, improved algorithms and data structures utilizing the DPDK open-source framework are designed together with a proposal to offload certain computation elements into hardware using the RTE Flow library. The result of this thesis is a set of modules and an implementation of classification components intended to be used within the DDoS Protector application. The resulting components are then properly tested. Finally, the performance results of the original and new implementations are compared. The application shows as much as five-times improvement in terms of packet rate when using 256 classification rules.
