Methodology for fault tolerant system state synchronization design and its recovery from faults
Szurman, Karel ; Fišer, Petr (referee) ; Racek, Stanislav (referee) ; Vlček, Karel (referee) ; Kotásek, Zdeněk (advisor)
In this Ph.D. thesis, a new methodology for the fault tolerant system state synchronization design and its recovery from faults is presented. A state synchronization method designed by means of the proposed methodology allows to repair the state of sequential logic elements implemented in the FPGA application logic, which cannot be repaired by the partial dynamic reconfiguration. The proposed methodology describes possible state synchronization design methods with respect to TMR granularity, dependence of the system function on its previous states and the system architecture. The methodology focuses on coarse-grained TMR architectures and state synchronization in the systems controlled by means of finite state machines or a processor. The use of the methodology is demonstrated on the CAN bus control system and the microcontroller NEO430, for which specific synchronization methods were designed. The systems reliability and new ability of the systems for recovery from faults were verified in the presence of simulated SEU faults. The experimental results and the contribution of this thesis are discussed in the conclusion.

Design of methodology for vulnerability assesment
Pecl, David ; Martinásek, Zdeněk (referee) ; Gerlich, Tomáš (advisor)
The thesis deals with the assessment of security vulnerabilities. The aim of this work is to create a new method of vulnerability assessment, which will better prioritize critical vulnerabilities and reflect parameters that are not used in currently used methods. Firstly, it describes the common methods used to assess vulnerabilities and the parameters used in each method. The first described method is the Common Vulnerability Scoring System for which are described all three types of scores. The second analysed method is OWASP Risk Rating Methodology. The second part is devoted to the design of the own method, which aims to assess vulnerabilities that it is easier to identify those with high priority. The method is based on three groups of parameters. The first group describes the technical assessment of the vulnerability, the second is based on the requirements to ensure the confidentiality, integrity and availability of the asset and the third group of parameters evaluates the implemented security measures. All three groups of parameters are important for prioritization. Parameters describing the vulnerability are divided into permanent and up-to-date, where the most important up-to-date parameter are Threat Intelligence and easy of exploitation. The parameters of the impact on confidentiality, integrity and availability are linked to the priority of the asset, and to the evaluation of security measures, which increase the protection of confidentiality, integrity and availability. The priority of the asset and the quality of the countermeasures are assessed based on questionnaires, which are submitted to the owners of the examined assets as part of the vulnerability assessment. In the third part of the thesis, the method is compared with the currently widely used the Common Vulnerability Scoring System. The strengths of the proposed method are shown in several examples. The effectiveness of prioritization is based primarily on the priority of the asset and the security measures in place. The method was practically tested in a laboratory environment, where vulnerabilities were made on several different assets. These vulnerabilities were assessed using the proposed method, the priority of the asset and the quality of the measures were considered, and everything was included in the priority of vulnerability. This testing confirmed that the method more effectively prioritizes vulnerabilities that are easily exploitable, recently exploited by an attacker, and found on assets with minimal protection and higher priority.

The dissertation deals with the assessment of navigation performance of GPS/EGNOS system in user position domain. Examination is based on a static signal in space monitoring and evaluation campaign to assess the ability to provide sufficient performance for new navigation procedures. GPS/EGNOS system is the first primary navigation system to be used in the airspace of Czech Republic. The first part describes the benefits of using new procedures, summarizes navigation development and current status. The second part defines components of GPS/EGNOS primary navigation system being analysed and its characteristics with the potential impact on the quality of approach navigation services to be provided and ensured by EGNOS. Subsequently, the methodology for critical evaluation of GPS/EGNOS signal in space navigation performance in position domain to be monitored by of air traffic services was formulated, using new methods for investigation of accuracy, integrity and continuity with the focus on final approach procedures. Simultaneously supporting software for data analysis against performance requirements in position domain was designed. Based on campaigns of static experimental measurements and detailed analysis of combined GPS/EGNOS performance against the demands, the level of performance is analysed, the findings are presented and conclusions are made. In the last part, the usage of permanent geodetic stations for regular evaluation of GNSS performance for civil aviation purposes is designed and verified, and the conclusions based on navigation performance evaluation of observations from all selected station in the Czech Republic.

Prostorová analýza letní rekreace u vody v České republice
Jansová, Eliška
This diploma thesis is devoted to the spatial analysis of summer recreation in the Czech Republic. The aim was to evaluate the localities of bathing waters that are contained in the database of UZIS in terms of elements of tourist attractiveness based on implementation assumptions. The evaluation of the results took place through a selected geographical analysis based on selected spatial attributes such as distance to the village according to its size, location in protected landscape area or national park, transport accessibility, convenience of services and tourist attractiveness of the area. Subsequently in the work bathing locations are classified into four groups according to the dimension of their importance. The thesis is supplemented by research among operators of bathing locations which are part of the evaluated database. The result of the thesis is that the locations of the water is in PLA/NP significantly affects the offer of services in the location. The best available type of bathing water is swimming polls, and the least available are water tanks. Bathing locations that are part of the municipality and are equipped with services can be found mainly in administrative district of the municipality with extended jurisdiction with a significant or very significant level of tourist intensity.
