Implementation of plugins for JMeter
Švehlák, Milan ; Člupek, Vlastimil (referee) ; Martinásek, Zdeněk (advisor)
This thesis discusses the load testing tool JMeter and its opportunities for expansion by modules carrying out cyber attacks of the type Denial of Service (DoS). To begin with, there is a theoretical overview of cyber attacks of this type. The following chapter, talks about the JMeter tool, namely its functions and expansion options. After that, it is proceeded to the actual design and realization of the modules. The module implementing the attack HTTP Flood is created first. This module uses internal functions of the program JMeter. This new module is tested. Next chapter folows the procedure of creating modules, that use external generator of network traffic. Modules SYN Flood, ICMP Flood and NTP Flood are implemented using the generator Trafgen. Module implementing attack Slowloris uses a Python script as a generator of the attack. Finally, all the new modules are tested.

Static methods for detection DDoS attacks
Miško, Lukáš ; Dvořák, Jan (referee) ; Blažek, Petr (advisor)
This thesis contains a theoretical basic for solution to issue of network anomalies with use of static methods and it also contains software as a solution for detection of network attacks. The main point of thesis is detection of DoS (Denial of Service) attacks. In thesis is located an analysis of DoS attacks rate categorization. Further in thesis is located analysis of protocols TCP (Transmission Control Protocol) and UDP (User Datagram Protocol), their possible use to attacks SYN flood and UDP flood. Here are analysed three static methods and their detailed description. There is also a analysis of collected data and their comparison in the thesis. Thesis contains description and the results testing of software which is used to detect attacks in network, at the end.

Similarities and differences are both covered. Relation of sonhood, authority and god is crucial, as well as the change of the whole concept of father - son relationship which occurred in the 20th century.
