NNTP Server as a Windows Network Service
Loupanec, Josef ; Ráb, Jaroslav (referee) ; Očenášek, Pavel (advisor)
This work includes specification and analysis of requirements, design and implementation of the internet news server. The server controls newsgroups and associated news. It provides availability of the articles by NNTP protocol and HTTP protocol (by web interface). The server supports a user authentication and an optional proxy mode, when all NNTP requests are resent to another remote NNTP server. A mechanism that provides news-downloading from remote NNTP servers and performs distribution function is included too. The application is designed to run on MS Windows NT (and higher version) as a NT service. The server is configurable by a graphic user interface. The work also includes theoretical information needed for successful accomplishment of the above-mentioned requirements.

Transformation of N.e.s.p.i. System into Web Services
Fiala, Jan ; Lukáš, Roman (referee) ; Květoňová, Šárka (advisor)
The diploma thesis describes the analysis, specification, origin and transformation of the current editing system N.E.S.P.I, which is the intellectual property of the company WebRex s.r.o. The main aim is to separate the administration of the web sites from their content, which can be seen on the Internet and by doing so to achieve the unified and complex administration interface for the customers. By bringing the service into work we do not only save time and simplify the work of the programmers, but we are also able to reach the stage when the editing system is not only the intellectual property of the company, but also its physical property, because the customer owns only the web sites, but the possibility to administrative them is offered as further service. The service should also provide the customers with modern access to informational technologies and propose enhanced assistance for their entrepreneurial plans and ideals.

Data Extraction from Dynamic Web Pages
Puna, Petr ; Kunc, Michael (referee) ; Burget, Radek (advisor)
This work contains a brief overview of technologies for representation and obtaining data on WWW and describes selected web data extraction tools. The work designs a new tool for obtaining pages generated by filling in web forms, which allows its user to define data on such web pages and which can extract those data and offer it in a XML format suitable for future machine processing.

System for Remote Monitoring of Electrical Values
Kvasnička, Pavel ; Kněžík, Jan (referee) ; Drahanský, Martin (advisor)
The work deals with the measurement of electrical quantities, distribution of data across the Ethernet network into the Internet and intelligent selection of the required values to be transmitted and stored on a central node. The work describes the communication protocols in scale that is necessary for implementation, discussed the requirements for computational resources and microcontroller control is proposed by flowcharts. Attached are source codes in C programming language for microcontroller and PHP scripts for storing and presenting data on Web server.

System for Supporting Agile Project Management
Liška, Radek ; Burget, Radek (referee) ; Kreslíková, Jitka (advisor)
This project is devoted to using of agile methodologies in the process of the web development. First, the most widely used traditional and agile methodologies of the software development are theoretically examined. Based on the identified procedures are chosen those that solve the biggest problems associated with the project management of the web development. From the findings is given a rough design of the system with usage of agile procedures. In the final part of the project is mentioned design implemented as the system prototype.

Interception of Modern Encrypted Protocols
Marček, Ján ; Korček, Pavol (referee) ; Kajan, Michal (advisor)
This thesis deals with the introduction to the security mechanism.The procedure explains the basic concepts, principles of cryptography and security of modern protocols and basic principles that are used for information transmission network. The work also describes the most common types of attacks targeting the eavesdropping of communication. The result is a design of the eavesdropping and the implementation of an attack on the secure communication of the SSL protocol..The attacker uses a false certificate and attacks based on poisoning the ARP and DNS tables for this purpose. The thesis discusses the principles of the SSL protocol and methodology of attacks on the ARP and DNS tables.

Test Result Repository with Web User Interface
Vlasák, Jaroslav ; Letko, Zdeněk (referee) ; Kočí, Radek (advisor)
This thesis deals with the development of a client-server application for Red Hat company. Client participates in testing process of JBoss platform and gets user-defined performance data which sends during testing to the server application by platform independent communication. The server application allows to analyze the received data which can be also compared by several perspectives. These services for data analysis and comparison are accessible for server users using the web client. The server application supports the import of the performance data stored in the XML file and also their export for qVue portal. The client part of the application is implemented in Java and the server application is based on Java EE platform.

Identification of Useful Data for Lawful Interception
Holomek, Tomáš ; Veselý, Vladimír (referee) ; Polčák, Libor (advisor)
This thesis deals with the identification of useful data in lawful interception. First part summarizes the standards related to computer networks and lawful intercepts. Next part of the project focuses mainly on the HTTP application protocol, which is described in version 1.1. The work also specifies the classes into which the data traffic can be divided according to the importance to law enforcement agency. It introduces several methods of distribution of data streams into the proposed classes. Finally, the implementation of this methods has been tested for usability in network lines used today.

Web Services Security
Kubáni, Tomáš ; Doležel, Radek (referee) ; Malina, Lukáš (advisor)
The bachelor thesis analyzes the current state of Web services and their security. The first chapter describes the construction details, options and features web services, with primary focus on the technologies (SOAP, XML, HTTP, WSDL, etc.) used for communicating and processing information and resources. The most important part of this work is focused on cryptography and security for these services. The essence of cryptography and encryption methods is explained, the main safety requirements and security mechanisms is pointed out, security standards are presented and compared. Finally, the bachelor thesis contains the theoretical and practical proposal of our secure Web Service, according to selected and necessary criteria.

A Tool for Robustness Testing of Web-Services
Zelinka, Tomáš ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This project deals with testing of web services. The result of this work will be a tool for load testing of web services using fault injection in their communication. The first part of the project discusses the basic aspects of testing web services. The second part of the work is more focused on testing high loads in combination with fault injection. The tool will allow automated run of the tests. The distributed model of the tool was designed to simulate real loads. In the last chapter are summarized achieved results.
