Email Server as a Windows Network Service
Jalůvka, Petr ; Ráb, Jaroslav (referee) ; Očenášek, Pavel (advisor)
Email is one of the most used services on the Internet. It's hard to find a user with less than one own mailbox. These mailboxes are usually located on servers controlled by someone else than mailbox owners. Users trying to create their own email serverhave to install unix system and go through hard configuration process of the email server. Purpose of this work is to familiriaze reader with email history and protocols and then introduce design and implementation of an email server with easy configuration for Windows NT platform.

International Alphabets in Network Traffic Monitoring
Talašová, Irena ; Vrána, Roman (referee) ; Polčák, Libor (advisor)
This work deals with the implementation of support for network identifiers containing national characters in the SProbe software project, which is designed to monitor network flows. It was necessary to test and evaluate the status of selected network applications working over SMTP, POP3, IMAP, FTP or SIP protocols. On the basis of the information obtained, an extension of the current software project SProbe was proposed - a module to support network traffic monitoring with national alphabet characters. The proposed solution was then implemented and the functionality of the entire resulting system was tested. In addition, this work proposes and implements a modification of the test environment for faster and more efficient testing of the system focusing on tests containing diacritics.

Network Protocols Semiautomatic Diagnostics
Svoboda, Ondřej ; Ryšavý, Ondřej (referee) ; Holkovič, Martin (advisor)
This thesis is about semiautomatic network protocol diagnostics and creating protocol description from eavesdropped communication. Several network eavesdropping techniques and some common programs for network analysis are introduced. Well-known network protocols are described, with focus on their communication messages. Some already existing methods for creating models from examples are mentioned and their characteristics defined. Next we design architecture of developed tool and some methods, that create protocol description. After that we explain implementation of this tool and finally the tool is tested and experimented with.

Open Call
Gajdošík, Andreas ; Rathouský, Luděk (referee) ; Sterec, Pavel (advisor)
In diploma thesis Open Call I focus on unequal position of artists in current art world in which, despite the transparent practices like open calls, still persists the cult of name, the power of networking and personal recommendation. This topic I artistically process in form of practical artistic intervention, which is close to the tactics of 1:1 scale of Arte Útil - specifically by creation of software tool called Nomin. Its purpose is to support weakened or marginalized groups of artists. Nomin uses properties of email protocol SMTP to allow its users-spectators to send fake self-recommending emails - from email addresses of famous curators to the inboxes various galleries or other art institutions. During development of program Nomin and its technical background (software documentation, web page etc.) I followed the paradigm of free, libre, open source software (FLOSS) and also the methodology of agile software development in order to provide in this gesamtsoftwerk the users-spectators with fully functional, user-friendly software and give them possibility to influence further development of Nomin or directly participate on it. Created artwork is thus not a single artefact but rather a set of interconnected objects and practices grounded in the network of social bonds and behaviours which balances on the edge of institutional critique, useful art, participatory art and collective performance.

Analysis and Visualization of e-Mail Marketing Campaigns
Urbanczyk, Martin ; Holkovič, Martin (referee) ; Hynek, Jiří (advisor)
The goal of this thesis is evaluating Posílátko.cz application and making extensions on the basis of thorough analysis and comparison of other similar products. This extensions are going to lead into increased user awareness of campagins state, so user can react accordingly. Extensions are going to be founded mostly on statistics data. Next I am going to implement campaign summary documents, where people can find all the data without logging into the application. So user can take this documents and present it easily on corporate consultations.

Traffic detection and analysis using SSL/TLS
Hutar, Jan ; Dvořák, Jan (referee) ; Smékal, David (advisor)
This diploma thesis deals with a detection and analysis of secure connections of electro- nic communication through SSL/TLS protocols. The thesis begins with introduction to SSL/TLS protocols. Thereafter, an analysis of messages used to establish secure con- nections using STARTTLS and postal protocols SMTP, POP3, and IMAP was made. Metadata detection and extraction of secured simplex and duplex connections take place using deep packet inspection tools. The tool of choice is the nDPI library from the Ntop project. The library was extended to detect the connections and extract the metadata based on studies and analysis of transmitted messages. Finally, testing is performed on a training data set and a basic analysis of acquired metadata is made.

Probe for the Application Protocols Monitoring
Fukač, Tomáš ; Košař, Vlastimil (referee) ; Viktorin, Jan (advisor)
This work describes an extension of the Microprobe functionality for detection and filtering of application protocols. The Microprobe is an embedded system designed for monitoring network links at speed 1 Gb/s without loosing any packets. The detection of application protocols requires using of computationally expensive operations, especially string lookup (usually based on regular expressions). Based on the study of several protocols (SMTP, POP3, FTP, SIP) a draft of a new architecture has been created. The new architecture splits this functionality between programmable logic FPGA and processor. The FPGA performs preprocessing of network traffic consisting of a lookup for user identifiers and protocol-specific patterns. The processor verifies that it is the requested communication. The processor does not need to process the entire network traffic but only the part pre-filtered in the FPGA. The software part is extended by a module for the analysis of SMTP which allows processing of more than 5,000 network flows per second. Support for other protocols can be added by an extension of the software part.
