Cloud computing - comparison of cloud storages
Tymeš, Radek ; Vaněk, Jiří (advisor) ; Daniel, Daniel (referee)
This thesis deals with the utilization of cloud computing in the field of online data storages for storing and backing up of user data. After defining the target group and its requirements for the service, ten most suitable options from the total set of cloud storages were selected. Selected storages were subsequently tested and analyzed in order to be used in the next stage of thesis. Materials for multicriterial analysis of options were created on the basis of set criteria and their given or measured values. The most appropriate options were calculated by application of the aforementioned mathematical method. These options were then evaluated and described from the viewpoint of commissioning.

A guide to designing optimal method of backup for big volumes of data
Bartoňová, Veronika ; Vychodil, Petr (referee) ; Burda, Karel (advisor)
This diploma thesis deals with backup for big volumes of data. Data backup is a overlooked area of information technology and the data can be lost by trivial user error or breakdown on any components. In this thesis is discussed theory of backup - archive bit and his behavior based on various type of backup (full, incremental, differential or combination thereof), duration and frequency of backups or the point of ultimate recovery. In addition there are mentioned rotation schemes Round-Robin, GFS and Tower of Hanoi, where are described their principles and graphic diagram of rotation. In chapter Strategy of backup describes the backup strategy via choosing the right choice, taking into technical and economic parameters. Impact analysis, which is explained also in this chapter, describes the important moments in data recovery. For select the optimal strategy is necessary to consider not only the whole capacity of the backup data, but also the size of the backup window for data storage or storage location. In chapter Media storage you can acquainted with all backup media and their technical parameters that are available on the market and can be used for data backup. In section Guide methodology of large volumes of data backup is designed a backup plan with the necessary inputs for the actual implementation of the backup. The design methodology puts emphasis on regular backups and check their location. On practical demonstration is shown that the rotation scheme Tower of Hanoi are among the smallest need for backup media. A part of this thesis is also design of methodology for backup small amounts of data.

Teaching of digital safety at the secondary and high school
ZELENKA, Jakub
This thesis deals with the issue of digital security at primary and secondary schools. This means first of all taking into account important aspects of computer security, such as protection of your equipment from dangerous viruses and pirate attacks with security software, the correct backup and manage their data. Furthermore, the focus on prudent behavior on the Internet, including caution against email threats, fraudulent behavior of some users and prudent use of social networks. It also provides password security with an emphasis on strong password management and also the issue of copyright law. The work included content analysis of Czech curricula given to the issue. They are listed here similar studies related to the topic of research theory and the main research of this thesis. In this research included a survey investigating the competence of students of the above schools in teaching computer security, the results are evaluated and compared with the findings of state documents related to the issue of teaching ICT.

Data security of the fire department of the South Bohemian region
REMIÁŠ, František
The thesis is focused on work with the data and information for the Fire and Rescue Service of South Bohemia Region, and its goal is to determine whether the data and information faced by members and employees of Fire and Rescue Service in their work are treated in accordance with applicable legislation, and whether they are adequately secured and protected against misuse and loss. Based on the organizational structure of qualitative research are mapped in detail the security and protection of data on individual departments and workplaces. These information compile risk areas for different types of data and due to this is prepared the risk map for these areas. Due to the findings the specific measures are designed to mitigate the risks for certain fields of work with data and information. The first part explains the basic concepts and definitions of words data, information and knowledge. The next section discusses the historical context of the mapped datastorage and handling of data in paper and electronic form, including the development of information systemsand technologies. Further are described the possible threats by varius effects on these data. Another chapter focuseson describing the current state ofwork with data and description oftechnologies used to it at the Fire and Rescue Service. Afterwards is elaborated an organizational structure focused on work with data. In following part the risk map is prepared for each area and proposesseveral solutions and particular measures to reducethe greatest of the resultingrisks. The benefit of this work is the implementation of several specific solutions to eliminate and reduce the threat of risks when working with dataat Fire and Rescue Service of South Bohemia Region, and several otherproposal measures and stepsfor additional security and data protection.
