Monitoring of services within active network elements by Mikrotik
Kamenář, Filip ; Slavíček, Karel (referee) ; Grenar, David (advisor)
This bachelor thesis deals with the monitoring of the VPN services on the networking elements Mikrotik. The theoretical part includes the description of RouterOS system, management options and networking devices used. The thesis consists of the description of the VPN services and analysis of PPTP, SSTP, L2TP and OpenVPN protocols, which are implemented in the practical part of this work. The theory also contains the description of monitoring devices included in the RouterOS system. In comparison, external tools are enlisted. Chosen monitoring tools are therefore implemented in the practical part of the thesis and in the monitoring script. The practical part of the bachelor thesis is focused on the establishment of VPN tunnels and its parameter measurement. The VPN clients are to be found in the Czech Republic, Ukraine and Egypt, which establishes the real conditions for network monitoring status. The final part of the work deals with the script, which is created for the automatic-monitoring of VPN service in the accessible network and sends the gathered data to the operators. The aim of the thesis is to illustrate the usage of integrated monitoring tools in the RouterOS system in the network built on the Mikrotik elements. The chosen monitoring service was the service VPN, which is being used for remote access to the local networks from distant part of the world by the corporations but also individuals. Individual monitored parameters are enlisted and compared depending on client geographic location.

Tool to support DoS testing
Kamenář, Filip ; Gerlich, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
The master thesis deals with denial of service attacks and their implementation in own application, called ptdos, that allows testing of web applications using the implemented attacks. Ptdos is also capable of monitoring the progress of testing as well as its evaluation. In the theoretical part of the thesis, the basic concepts are defined, the classification of attacks into categories is described and the individual attacks are discussed in detail in order to explain how the denial of service should occur in the context of an attack. The practical part of the thesis describes the design of the ptdos application architecture and its subsequent development, including a description of the implementation of all the selected attacks. The last part of the thesis is the testing of the application, which includes the creation of a test network and the analysis of all implemented attacks using different scenarios.

PTDOS:Tool to support DoS testing
Kamenář, Filip ; Martinásek, Zdeněk
Nowadays, cyber attacks are a common part of our lives. Targets of attacks are various, such as obtaining sensitive data, network infiltration, system sabotage or denial of service (DoS). This paper deals with the attacks that target denial of service. The main goal is the custom design and development of the ptdos application, which allows testing of the resilience of network infrastructure and web servers against these types of cyber attacks. The application will be freely available and will contain various types of attacks (both flood and logic) to sufficiently test the system. The purpose of the work is to create a quality and simple tool to enhance cyber security.
