Board Game User Interface with a Camera
Cihlářová, Dita ; Hradiš, Michal (referee) ; Zemčík, Pavel (advisor)
Cílem této práce je vytvořit systém, který bude schopen nahradit reálného protihráče ve hře Dostihy a sázky. Hra je snímána kamerou, ze které se obraz přenáší do počítače, kde probíhá zpracování obrazu a identifikace herních objektů. Dále aplikace analyzuje stav hry a rozhodne o svém následujícím tahu. Rozhodovací algoritmus je schopen reagovat na každou herní situaci a tudíž dohrát hru do konce. Aplikaci mohou využít hráči, jež rádi hrají Dostihy a sázky, ale chybí jim protihráč. Aplikace také může najít uplatnění jako demostrace možností počítačového vidění.

Camera Recording Management System
Šulc, Ondřej ; Rychlý, Marek (referee) ; Očenášek, Pavel (advisor)
The aim of this bachelor thesis is to create a network security system focusing on compatibility with the widest possible group of IP cameras from various manufacturers and support for remote access to records even from places outside the local network. This problem is solved using two closely cooperating applications. The first application runs on a device in the local network (in our case miniPC Raspberry Pi). The application creates the records by receiving and storing RTSP transmissions from individual cameras. It then modifies these records into a form usable for display on websites and sends the second application from which the user can access them. This application is referred to in the text as agent or agent application. The second application has a web user interface and serves the end user as a tool to manage agents, IP cameras and captured records. By principle of the application, it is important for it to be accessible on a publicly available domain. This application is referred to in the text as web or web application. The use of this architecture does not violate any of the network communication standards, which include, in particular, the initialization of communication from the network behind the NAT service.

Virtualization of operating systems
Král, Jan ; Malina, Lukáš (referee) ; Komosný, Dan (advisor)
The diploma thesis ’Virtualization of Operating Systems’ deals with a general description of virtualization technology and briefly discusses its use cases and advantages. The thesis also mentions examples of different types of virtualization technologies and tools, including more thorough description of the two technologies used for measurement: Docker and KVM. The second part of this thesis descibes the preparation, installation and configuration of all the tools and services that are necessary for measurement of the influence of the aforementioned virtualization technologies on network services running on the virtual machines, including analysis and discussion of the resulting data. Moreover, a custom application for fully automated measurement of the parameters of network services was created, and is also described in this thesis. The conclusion of this thesis summarizes and discusses the achieved results and acknowledges the influence of virtualization on network services, where the Docker application containers, which are with their low overhead comparable to a "bare" system without any virtualization, managed to achieve much better performance results than the traditional virtual machines on KVM.

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.

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.
