Configurable Security Email Proxy
Židek, Stanislav ; Samek, Jan (referee) ; Cvrček, Daniel (advisor)
This bachelor thesis deals with design and implementation of multiuser configurable system capable of securing communication via electronic mail. Emphasis is put especially on remote configuration. It also describes existing protocols used for this communication and some of the mechanisms that can secure this communication from different points of view.

IMAP Proxy for POP3 Mailboxes
Kružliak, Miroslav ; Burget, Radek (referee) ; Kolář, Dušan (advisor)
This bachelor's thesis deals with retrieving e-mails from different accounts on POP3 servers and their organisation in one account on IMAP server. It also studies settings and configuration of IMAP servers in enviroment of operating system Linux. Protocols IMAP and POP3 are briefly compared here from implementation point of view. Further it studies possibilities of periodical start of processes and secure saving of sensitive information. In this part of my thesis main methods of cryptography are shortly confronted.

Efficient Transport of Electronic Mail with Microsoft Exchange Plugin
Jakubis, Tomáš ; Homoliak, Ivan (referee) ; Kováčik, Michal (advisor)
This project discusses optimization of e-mail and SMTP traffic in proprietary product of Microsoft Exchange 2013 in regard of marine industry. The goal is at first to analyze the requirements of this service on slow and unreliable network connections, SMTP traffic and then the product itself. Afterwards it defines specification for the final product and prepares the test environment. Design and implementation of transport agent using Exchange Management Shell is described for synchronization of two installations of Microsoft Exchange 2013; and focuses on emerged problems during the development, discusses different approaches and possible solutions. Testing shows various shortcomings of found solution. Finally, analysis of final solution shows possible future improvements and a need of security upgrade before applying to production environment.

Startup On-Line Dashboard
Pecsérke, Róbert ; Skála, František (referee) ; Szőke, Igor (advisor)
The purpose of this bachelor's thesis is to analyze, design and develop a web application that allows registered users to create an email account with a random name - dropbox. Users can either redirect emails generated by other services or send their emails to the dropboxes. The application searches for specific data in these emails and to visualize their change over time. This thesis also verifies the interest of users of this type of service.

Implementation of multi-purpose server based on WINDOWS
Depiak, Petr ; Kouřil, Jiří (referee) ; Pfeifer, Václav (advisor)
This thesis puts brain to the pieces of knowledge of the network services which are occurred in the server systems. These services are related to data storing, transport and data interpretation. Basically there are transport services which are used by FTP and SMB protocols. These protocols define them generally and their security too. Next section describes principles and application possibilities of electronic mail. It is based on SMTP, POP3 and IMAP protocols. The important part of this thesis is the World Wide Web service exploiting the HTTP protocol. It also refers to creation of dynamic presentation of electronic document by using the MySQL relational database and PHP script language. Practical part goes out of the theoretical part discussed above and all services are implemented on the MS Windows 2003 Server EE R2 platform. The main scope is oriented to the highest usage of data security within the available software. Other part presents the introduction to hosting of the Novell eDirectory service. It is practically applied on the MS Windows platform. This application also includes the administration of eDirecroty service by using the standard tool. This tool allows the administration though the web interface.

IMAP Implementation in C++
Pohl, Marek ; Janoušek, Vladimír (referee) ; Peringer, Petr (advisor)
This thesis has focused on development of library of IMAP network protocol in C++ programming language. This work has focused on design and on interface of the library. Object design of this library is based on analysis of the IMAP protocol. Developed library contains implementation of a client and server part of the IMAP protocol. This work shows also the another IMAP libraries and evaluates pros and cons of the different solutions. Security of a network transfer is explained here in this thesis. This work deals with authentication methods, which are used to protect user credentials during authentication process. Created library can be easily used by software developers to develop an applications like an email client program and IMAP mail server. Part of this work has focused on testing of this developed library.

Artificial Immune Systems for Spam Detection
Hohn, Michal ; Sekanina, Lukáš (referee) ; Schwarz, Josef (advisor)
This work deals with creating a hybrid system based on the aggregation of artificial immune system with appropriate heuristics to make the most effective spam detection. This work describes the main principles of biological and artificial immune system and conventional techniques to detect spam including several classifiers. The developed system is tested using well known database corpuses and a comparison of the final experiments is made.
