The main purpose of the study is to present basic orientation in particular authorizations to represent public law when enforcing road safety regulations. The study is composed of three main chapters devided in relevant subchapters, each of them dealing with different aspects of the administrative law. The first chapter briefly describes the origins of enacting the municipal police as a municipal body, pointing out the past difficulties, followed by the summary of the law regulation establishing the municipal police and controlling its activities by the municipal self-government. It also defines the municipal police as a part of the administrative law. In the main second chapter the single competencies are described, divided into subchapters by its source according to the Municipal police Act and the Road traffic Act. The permition to control speeding and testing the drunk drivers are most widely described, followed by the issue of towing vehicles. The history of each competency is recognized and then the study brings basic description, aims on the practical issues and tries to find legal solutions using the Czech case law. The...

Centralization of Java Security Policy Management
Kalina, Jan ; Rogalewicz, Adam (referee) ; Letko, Zdeněk (advisor)
WildFly is a platform for distributed environment which meets specification of Java Enterprise Edition. This thesis deals with possibilities of centralized management of security policies in this environment. Security policy is a set of permissions to which the Java virtual machine (JVM) limits possibilities of running applications. Just possibilities of security policy using was in WildFly so far heavily restricted. The result of the thesis are extensions of WildFly which add possibility of central deployment of security policies to individual servers, without need for restart that server, into program interface of WildFly and into WildFly management console. Part of result is also patch of core of WildFly, which solve problem of exchange security policy at runtime of JVM.

Automatic configuration of workstations in Cisco academy laboratory
Homolka, Jiří ; Jelínek, Mojmír (referee) ; Komosný, Dan (advisor)
My thesis is focused on the subject of working with distant stations connected with the laboratory control of Cisco academy. Station operations, i.e. laboratory control, have been carried in the environment of the Linux operating systems. The first part of the thesis includes a description of the laboratory, its network architecture and software equipment. Also, the VMware tool is described here. VMware tool is intended for virtualization of computer stations, where the virtual station is created. In this virtual station another operating system may be run. The problems of the command interpreter, its function and possibilities are described here too. Main attention is devoted to the Bash command interpreter and to the creation of the scripts. There are descriptions of the basic tools intended for the network communication with the distant stations. Among the most important parts belong the protected communication, the production of the autentization keys as well as the tool for data recording on more stations at the same time. The description of the access rights to the files and directories is included too. The target of this thesis was to create the scripts in the Bash programming language. The scripts are focused on working with the laboratory stations. They are the sublayers of the common project for this laboratory control. They were developed for the cooperation with the the web interface and MySQL database, created by Bc. Zdeněk Hrabal. The Scripts are intended for the finding information about the stations and virtual systems, and also for the recording images and configuration files of the virtual systems at the distant stations. Recording files and directories is enabled too. The other scripts deal with the erasing and changing of the rights of the particular files and directories. Setting commads with the super-user competence is used at this place. The scripts for the switching on and off the laboratory workstations were created too. To solve the problem described above I chose to develope more scripts. Each of them subserves the particular part of the task. The form of the input and output data of the scripts was select with the reference to the cooperation with the web interface and database. The data are implemented by the form of the input and output files. The output information and the process of the carried operations are displayed through the web interface. The scripts together with the web interface are placed and run from the school server adela.utko.feec.vutbr.cz. In the thesis the settings of the access privileges for the current directories and the files of virtual systems and scripts are presented too.

Comparison of New Approaches to RBAC
Pithart, Josef ; Klas, Jan (advisor) ; Kejkula, Martin (referee)
Hlavním cílem předkládané práce je porovnání vybraných moderních přístupů k Role-Based Access Control (RBAC). Práce v první kapitole obsahuje stručnou charakteristiku RBAC. V další jsou pak vyzdviženy oblasti, na které se vybrané přístupy zaměřují a řeší je. Ve třetí části jsou detailně popsány jednotlivé přístupy. Popsány jsou čtyři přístupy, které se zabývají různými oblastmi uplatnění modelu RBAC. V poslední části jsou pak porovnány vybrané přístupy pomocí různých kritérií a ukázány jejich přednosti a nedostatky. V poslední části jsou také popsány společné charakteristiky a doporučen postup při využití přístupů v praxi.
