Generate ICMPv6 and IPv6 packets for load testing using JMeter tool
Šulka, Samuel ; Člupek, Vlastimil (referee) ; Dvořák, Jan (advisor)
The Bachelor Thesis deals with flood attacks using generating of ICMPv6 packets in an environment without IPv4 protocol. A Trafgen configuration file was created, which had the task of sending ICMPv6 packets. For other attacks was used Scapy in Python. A plug-in modul for software Apache JMeter was created for each scenario. Scenarios were tested on real device and the results were documented in write and visual form.

Denial of Service detection methods
Horský, Milan ; Zeman, Václav (referee) ; Sikora, Marek (advisor)
This bachelor thesis deals with a methodology for detecting and describing the Denial of Service (DoS) condition on a web server. The aim of the thesis is to develop and implement methods that enable effective detection of DoS attacks in an experimental network. The theoretical part focuses on the analysis of different types of DoS attacks, including their detection on the application server and network side, and discusses possible reasons for false positives. In the practical part, software tools for monitoring and analyzing server and network resources were developed and then tested against different types of DoS attacks. As a result of the work, the proposed methodology has been validated and implemented in an experimental network, which provides useful tools for improving the security and stability of web servers.

Prostředí pro testování algoritmů potlačení útoků DDoS
Patová, Pavlína ; Šišmiš, Lukáš (referee) ; Kučera, Jan (advisor)
The work is focused on creating a test environment for simulating DoS attacks. This environment is useful for verifying the vulnerability of networks and services against the phenomenon of DDoS attacks, therefore it will be used to test the tools and techniques developed to defend against DDoS attacks. The outputs of these experiments can then be used as recommendations for network administrators to help improve the refensibility of their systems. The resulting tool is implemented in Python using the PyTest module. We were able to implement many of today’s most common DoS attacks, such as floods and amplification attacks. It is thus possible to test services against these most serious DDoS threats. The resulting tool is easily extensible to other methodologies or attack types, so it can also be used for emerging DoS attacks in the future.
