The Influence of Cyber Terrorism Threat on the American Security Policy
Rezek, Tomáš ; Calda, Miloš (advisor) ; Mareš, Miroslav (referee) ; Cabada, Ladislav (referee) ; Polčák, Radim (referee)
(English) The aim of this dissertation is to answer the question of whether the U.S. security policy is influenced by the threat of cyber terrorism. The dissertation is divided into chapters that can be regarded as steps in a logical reasoning process. In the first chapter, cyber space is introduced and described to illustrate its importance and complexity. The next chapter analytically compares various definitions of terrorism, and partially rejects the initial hypothesis that cyber terrorism is not included in the general definition of terrorism. The following chapter statistically analyzes the available data on terrorist groups and terrorist attacks to empirically confirm the hypothesis that terrorism is still a real threat to American security. The analysis actually proves that the threat of terrorism has not decreased in relation to the number of terrorist groups. It also shows that the number of terrorist attacks against the U.S. targets has significantly decreased in the United States, while terrorist actions have been increasing constantly on a global level. The analysis shows that the success rate of terrorists attacks does not form a time series, and therefore each terrorist attack has to be examined individually to assess its success probability. The following analysis reviews the...

U.S. Homeland Security: Reality or Myth? Domestic counterterrorism post-9/11
Bernardyová, Alžběta ; Raška, Francis (advisor) ; Anděl, Petr (referee)
Diploma thesis "U.S. Homeland Security: Reality or Myth? Domestic Counterterrorism post-9/11" examines the change in U.S. domestic counterterrorism policy after the terrorist attacks of 9/11. More specifically, it focuses on the U.S. government's reorganization, which led to the creation of the Department of Homeland Security. As outlined in this thesis, the homeland security agenda was aimed at unifying the U.S. efforts to prevent terrorist attacks within the United States, reducing America's vulnerability to terrorism, and minimizing the damage and recovering from attacks that do occur. This thesis sets out to answer two interconnected questions: (1) whether the proposed homeland security agenda led to an efficient and unified system of U.S. domestic counterterrorism measures based on enhanced information sharing; and (2) why, in spite of the unique opportunity created by the 9/11 attacks, a comprehensive reorganization of the U.S. government to create a coherent homeland security agenda did not materialize. Throughout this thesis, it is argued that an efficient U.S. government reorganization was obstructed by three main factors. First, the change was obstructed by the organizational nature of the government agencies. Second, the reorganization was hindered by the "rational choices" of the U.S....

Comparison of knowledge from inhabitants protection at laical and expert community in selected region
JEŘÁBKOVÁ, Iva
Comparison of knowledge of the general and professional public on the protection of the population in the selected region. sufficient knowledge of public, no matter if general public or professionals in area of homeland security are required for preservation of secure environment for living. To process this thesis was first necessary to set goals. The goals of the study were stated as follows: - To define terms related to the protection of the population carried out in the Czech Republic. - To list conditions which the population must be protected from. - To list activities leading to improve homeland security and duties of responsible people. - To identify differences in knowledge of general and professional public on this issue - To compare the level of knowledge of specialists in homeland security and of general population based on proving or disproving the hypotheses about the level of knowledge. Firstly, to achieve the fundamental goal of this thesis was to create a structured overview of exceptional events that endanger life, health and property of population. Then were defined organisational and technical measures that have to prevent life loss, to mitigate the consequences that negatively affect health of population and minimize property damage. Based on the definition of all relevant aspects of homeland security was, under the supervision of a specialist in homeland security area, created a structured questionnaire which was subsequently applied by both the general and professional public. The form has been sent out to the group of 50 specialists and 50 unspecialized people. The existence of normal division of knowledge was verified among general population, while Poisson distribution was tested among specialists. During the measurement was also tested the difference between the knowledge of specialists and common people. To achieve the basic goal of the thesis were set three hypotheses, of which verification was based on descriptive and mathematical statistic methods. Hypotheses were set as follows: H1: The knowledge of homeland security area is spread by Poisson distribution function among specialists H2: The knowledge of homeland security area is spread by normal (Gaussian) distribution function among general population. H3: The level of knowledge of homeland security area of specialists is higher than general population's knowledge. The first hypothesis H1 was proved by 2 test and on its results was hypothesis H1 disproved. According to the statistic calculation the distribution of knowledge among specialists did not correspond to Poisson distribution, but theoretically is closer to Gaussian distribution. As for the second hypothesis, the distribution of the results of statistical measuring was compared to Gaussian distribution and by 2 test H2 was proved. The distribution of knowledge of the general public corresponds to Gaussian distribution. The third hypothesis was tested via a double-choose t-test method and based on its results it was found that there is a statistically significant difference between homeland security knowledge of specialists and general public. Hypothesis H3 was thus proved. The answers of respondents were presented by comparison bar charts of right answers of general and professional public, evaluated in discussion. At some of questions with big different results were described possible causes and offered changes for knowledge expansion. In the meaning of knowledge expansion there was created a feedback, sent backwards to respondents of statistic research. Attached to feedback is this diploma thesis.
