Detection of Dynamic Network Applications
Oroš, Petr ; Kaštil, Jan (referee) ; Tobola, Jiří (advisor)
This work deals with the detection of dynamic network applications. It describes a general method for detection of any application layer protocol and automatically searches for the detection rules. The practical part deals with general detection protocol to the automatically generated designs. A special section is devoted detect bittorrent protocol.

Torrent Peer Monitoring
Bezděk, David ; Pluskal, Jan (referee) ; Polčák, Libor (advisor)
This master's thesis deals with analysis and implementation of methods for BitTorrent monitoring focusing on the Mainline DHT protocol. The aim of the thesis was to create a system, that will be looking for BitTorrent peers that participe in the illegal file distribution. Another task of the system was to collect and analyze data for counting size of the BitTorrent network. That was achieved by taking over of existing method. The system was designed and implemented as a module for monitoring of cybernetic crime. It also defines an interface for storing and sharing data, that provides data evaluation, easy data manipulation and serves for possible future extensions.

Detection of Peer-to-Peer Communication
Letý, Pavel ; Kováčik, Michal (referee) ; Bartoš, Václav (advisor)
This thesis is focused on issues in detection of P2P network from NetFlow. In the theoretical part of this work are introduced actual techniques in detection of this communication in network. There are presented their advantages and disadvantages too. The biggest attention is focused on the classification scheme of Mr. Bashir which deals with a detection of a protocol BitTorrent and a Skype application from Netflow. Following this scheme is designed a detection module for a modular system of a traffic analysis Nemea, developed by Cesnet organization. In the practical part of this work is introduced the implementation of this module. There are also presented results of experiments with real data.

Detection of Dynamic Network Applications
Burián, Pavel ; Drahošová, Michaela (referee) ; Kaštil, Jan (advisor)
This thesis deals with detection of dynamic network applications. It describes some of the existing protocols and methods of their identification from IP flow and packet contents. It constitues a design of a detection system based on the automatic creation of regular expressions and describes its implementation. It presents the created regular expressions for BitTorrent and eDonkey protocol. It compares their quality with the solution of L7-filter.

Detection and Analysis of P2P Network BitTorrent Sync
Kutlák, Martin ; Polčák, Libor (referee) ; Matoušek, Petr (advisor)
Bachelor's thesis is focused on issues with detection of the P2P network BitTorrent Sync in network traffic. In the theoretical part of this work is introduced architecture of the P2P networks, BitTorrent Sync protocol and possible methods for P2P network detection. On the base of this knowledge is designed tool for detection of BitTorrent Sync network traffic. In the practical part of this thesis is presented implementation of the whole monitoring system. In the end of practical part are presented results of conducted tests with monitoring system.

Visual Home Security System for iOS-Based Mobile Devices
Bajaník, Filip ; Szőke, Igor (referee) ; Herout, Adam (advisor)
The goal of this diploma thesis is to design and implement a mobile application for home security system on the iOS platform. The application introduces a complex solution allowing the transmission of the audio and video streams between the paired mobile devices using WebRTC. The final module represents universal solution for peer-to-peer audio and video communication. The thesis also deals with the field of computer vision, namely efficient motion detection algorithms. The module for motion detection implements ViBe algorithm using Metal. In case that the motion is detected the application notifies a user with a push notification. Synchronization of application data is implemented using Cloudkit and the data persistance using Realm library.

The Copyright Law and its Infringing on Internet
Vlach, Aleš ; Dohnal, Martin (referee) ; Soukup, Tomáš (advisor)
My bachelor thesis "The Copyright Law and its Infringing on Internet" deals with a question of conflict in the area of the copyright law and internet. The thesis attends to most importand legal regulations of the international law, the European Union law and the law of Czech Republic. The work explains concept of the law (a work and its usage, copying, etc.) My thesis analyses particular problems of the law breaking with a view to quickly developing technologies in this area. The work also describes legal protections of technological instruments of creations and its breaking. It gives information on possibilities of sanctions resulted from the copyright law breaking. The work deals with possibilities of current problems solving.

Analysis of WiFi Traffic at the BUT
Lacina, Vojtěch ; Matoušek, Petr (referee) ; Čejka, Rudolf (advisor)
This work inquires into problem of current wifi traffic on VUT. The traffic has been captured with tcpdump program, anonymized and analyzed in process of creating this work. All this in order to get insight into it's nature. Resulting informations imply the need for traffic shaping which is described later in work. This work tries to determine most fitting means of traffic shaping which would result in improved quality of connection for interactive applications as well as greater satisfaction of provider (VUT) and users.

Reducing Peer-to-Peer Network Traffic
Šípoš, Martin ; Tobola, Jiří (referee) ; Žádník, Martin (advisor)
Bachelor thesis deals with peer-to-peer detection watching and reducing bandwith. An application was created for this purpose that is able to detect watch and control such networks at application layer or to block specified ports using opensource utilities. The application was created in Java language and is dedicated to Linux operating system.

Detection of P2P Networks
Vrba, Jindřich ; Kaštil, Jan (referee) ; Tobola, Jiří (advisor)
This thesis deals with peer-to-peer network detection. It describes possible techniques of identification on various ISO/OSI Layers. The goal of the practical part is to examine detection on the L7 layer by means of string patterns. A presentation of the results with graphs on web pages is also included. The application is intended for the GNU/Linux operating system.
