Secure Remote Computer Management System
Heško, Peter ; Hranický, Radek (referee) ; Polčák, Libor (advisor)
Deployment and management of remote systems poses several problems. Their administration and monitoring is much faster and more cost-effective when done remotely than when physical access to the system is required. Software that allows this is in many cases not freely available or has limited functionality. In this work I deal with the analysis of available solutions and then design and implementation of an application that combines all the required features. The result is software that provides secure access to and monitoring of remote computers running Ubuntu 16.04.

Telemetry Data Collection and Evaluation
Spurný, Jan ; Krajsa, Ondřej (referee) ; Číka, Petr (advisor)
This thesis describes design and creation of application which collects and values telemetry data. Thesis consist of design and implementation which describes whole system, server settings as well as approach how to consume any given data. Corner stone of this application is based on given data from telemetry station (sensors) and projecting them on the map background. Application consist of user interface and logic how to project any given data into the map. Graphics interface is created using HTML, JavaScript and CSS programming languages. Logic itself is programmed by using backend language PHP including Laravel Framework in combination with MySQL database. Result of this thesis is working implementation covering administration user interface, working cooperation of MQTT server and APIs. There are also implemented all necessary parts for enablement of user interface with cooperation with map background layer. Implementation creates two possible ways how to install package necessary to run this app on Ubuntu system.

Wireless communication analysis using software defined radio
Štrajt, Martin ; Štůsek, Martin (referee) ; Pokorný, Jiří (advisor)
The work deals with the use of software-defined radio as a probe for monitoring the operation of wireless communication according to the IEEE 802.11a/g standard. In the theoretical introduction, the concept of software-defined radio as a hardware device with software programmable circuits enabling the transmission or reception of signals in theoretically any frequency band is introduced. The introduction also contains adescription of selected devices and the IEEE 802.11 protocol with its most used additionsand modulations. In the first part of the practical part of the work, wireless communication is capturedusing a wireless network card in monitoring mode. The intercepted communication was decrypted and this decrypted traffic was compared with the data captured by the probe within the network. These results then served as acomparative basis for software-defined radio capturing. The focus of this work is to verify the capabilities of software-defined radio and its use for sniffing wireless communicationin the frequency band 2.4 GHz and 5 GHz. The attempt to use a software-defined radio here results from the scalability and adaptability that a wireless card cannot offer due to fixed hardware parameters. LimeSDR mini, LimeSDR and bladeRF 2.0 devices were used for capture. First, the configuration of the operating system, the installation of drivers and programs for control and work with selected devices are described. After verifying the functionality of the software-defined radio, a model of a signal decoder with the parameters of the IEEE 802.11g standard captured from the radio spectrum was put into operation. Finally, the data streams captured by the software-defined radio and the wireless network card were compared side by side. The results showed that the software-defined radio in the used configuration captures only a part of the total volume of transmitted frames.
