Web Portal for Network Traffic Reporting
Krebs, Lukáš ; Straka, Martin (referee) ; Tobola, Jiří (advisor)
The thesis deals with creating a web portal for generating statistics about the network traffic. There is presented the NetFlow technology, which is used in this thesis. Then there is described tho whole development process from analysis, design and implementation of the system to its testing. The whole program is created in languages XHTML, CSS, PHP and uses a MySQL database for a data storage. For a data mining is used NfDump.

Web Portal for Network Traffic Reporting
Klement, Ondřej ; Žádník, Martin (referee) ; Tobola, Jiří (advisor)
The main subject of this bachelor thesis is an proposal, analysis and implementation of the web portal for network traffic reporting. This work also deals with analysis of creating graphs, tables and statistics from data gained by NetFlow technology. The NetFlow technology itself is the key element in this thesis and this work is based on it. The main goal of this thesis is to make a simple tool for monitoring and analyzing the network traffic by generating complex reports. For the implementation itself, PHP and HTML have been chosen. Reports will be generated as well-know PDF documents.

Detecting P2P Networks Using NetFlow
Starigazda, Michal ; Čejka, Rudolf (referee) ; Matoušek, Petr (advisor)
This thesis addresses the problem of identifying P2P networks within NetFlow traces. There are presented different methods for identifying P2P networks. Their advantages and disadvantages are discussed in compare to a method using NetFlow technology. This method is based on traffic characteristics and behaviour of specific application. The theoretical section presents characteristic features of P2P systems in general. A system based on these and more application-specific features is proposed to detect selected P2P application -- BitTorrent. Finally, a NfSen plugin for detecting BitTorrent protocol within network traffic (using NFDUMP tools) is implemented. Detection targets users of BitTorrent protocol using NetFlow traces without inspecting the payload of the packets.

Protecting Local Network Using NetFlow
Hanousek, Vít ; Polčák, Libor (referee) ; Matoušek, Petr (advisor)
This bachelor's thesis deals with the use of NetFlow data for monitoring local networks. There is an analysis of the best known threads for a local network in the first part of the thesis. Detection algorithms based on signature NetFlow detection were implemented for the chosen threads. Four plugins for an open-source application NfSen are outputs of this thesis. These plugins detects the following threads: vertical and horizontal scans, dictionary based attacks on SSH protocol, spam machines.

Web Portal for Network Traffic Reporting
Dufek, Milan ; Straka, Martin (referee) ; Tobola, Jiří (advisor)
This thesis deals with gathering and analysis of statistic data about network traffic, it also deals with preserving and displaying such a data. The goal of this thesis is simple and quick user interface in web portal. The source of the statistic data is NetFlow technology. We use NfDump tool for reading the gathered data. Implementation is done in PHP, XHTML, CSS and JavaScript. SQLite Database is used for preserving the data.

Information System for Fair User Policy Management
Vykydal, Oldřich ; Žádník, Martin (referee) ; Tobola, Jiří (advisor)
Main goal of this bachelor's thesis is to design and implement information system for the management of Fair User Policy, or abbreviated as FUP. This whole project is based on the use of NetFlow technology to monitor the computer network through the monitoring of network flows. The resulting information system will enable network administrators to set limits to customers in the volume of transferred data and subsequent monitoring of their compliance. If the customer is in breach of these limits, the information system will allow the penalty. The system will also record some statistics on network traffic.
