In the last decade, Distributed Denial of Service (DDoS) has become the tool of choice for malicious people to disrupt online services from any internet connected website. Firewalls are one of the primary tools for a network to guard against any threat and malicious activities including DDoS. They come in two different forms, software based and hardware based. In order to choose the most effective firewall for preventing DDoS attack, firewall performance needs to be tested and the results should be analyzed.
This thesis analyzes the performance differences between a hardware and a software based firewall against different types of DDoS attacks. The performance will be measured based on user access time, firewall resource management and theoretical throughput efficiency.
The result shows that a hardware based firewall better defends against layer 3 and layer 4 DDoS attacks while the software based firewall better defends the network against layer 7 DDoS attacks.
