Internet, terror e ciberterrorismo : uma análise comparativa

Alcântara, Bruna Toso de January 2018 (has links)
Com o objetivo de identificar a diferença entre o uso da Internet por terroristas e o uso do ciberespaço com fins políticos para o terror, a pesquisa proposta se desenvolve em cinco capítulos, além da introdução e conclusão. O capítulo 2 busca elucidar como os mundos físico e virtual se entrelaçam, explicando a vulnerabilidade das Infraestruturas Críticas aos ataques cibernéticos que geram o medo sobre o ciberterrorismo. Seguindo, no capítulo 3 explica-se o debate sobre a percepção acadêmica acerca do uso do ciberespaço por terroristas e, no capítulo 4, uma amostra de países relevantes para o combate ao terrorismo é posta em comparação, a fim de se entender as percepções políticas acerca do uso terrorista do ciberespaço. Nesse sentido, o estudo em voga, hipotético-dedutivo com caráter qualitativo em meio às análises e comparações, validou a hipótese de que, embora pertencentes a paletas do mesmo escopo, o uso da Internet por terroristas e o ciberterrorismo possuem diferenças significativas, sendo elas elencadas dentro de quatro categorias analíticas: Utilidade do ciberespaço, Foco Operacional, Uso de violência e Objetivo Último. Por fim, essas diferenças foram postas na conclusão como propostas de tipologias para a definição do fenômeno do ciberterrorismo e do uso terrorista da Internet, partindo da conceituação de terrorismo proposta por Eugênio Diniz (2002). / In order to identify the difference between the use of the Internet by terrorists and the use of cyberspace for political purposes for terror, this research developes itself in five chapters, in which, in addition to the introduction and conclusion, in chapter 2, it seeks to elucidate how the physical and virtual worlds intertwine, explaining the vulnerability of Critical Infrastructures to cyberattacks that generate fear about cyberterrorism. Chapter 3 explains the debate about the academic perception of the use of cyberspace by terrorists and, chapter 4, a sample of countries that are relevant to the fight against terrorism is compared in order to understand the perceptions about the terrorist use of cyberspace. In this sense, the present hypothetical-deductive study with a qualitative character, in the midst of the analyzes and acquisitions validated the hypothesis that although belonging to palettes of the same scope, the use of the Internet by terrorists and cyberterrorism have significant differences, and they are listed within four analytical categories: Usefulness of cyberspace, Operational Focus, Use of violence and Last Objective. Finally, these differences were put in the conclusion as typology proposals for the definition of the phenomenon of cyberterrorism and the terrorist use of the Internet, rooted in the conceptualization of terrorism proposed by Eugênio Diniz (2002).

Ciberativismo: a política em tempos de internet / Cyberactivism: politics in Internet time

Nascimento, Sílvia Ramos Bezerra 17 March 2015 (has links)
O objetivo desta tese foi compreender como o ciberativismo, na condição de práxis centrada no uso programático da Internet, se insere no contexto das manifestações políticas ocorridas na Europa, Oriente Médio, EUA e Brasil, entre os anos de 2010 e 2013. Com isso, buscou-se refletir sobre as transformações da política na contemporaneidade, em face do transcurso da atual crise econômico-ecológica. Por intermédio de análises dos pensadores da teoria crítica (Marx, Adorno, Horkheimer, Debord) e da Nova Crítica do Valor (Kurz, Jappe, Trenkle), este estudo apresenta um modelo teórico que denominamos paradigma do antipoder, que partiu da obra de John Holloway, para entender a esfera pública oposicional praticada na Internet em sua tendência a uma práxis de ação direta, aberta, livre e anticapitalista. / The objective of this thesis was to understand how the cyber activism, on condition of praxis focused on programmatic use of the Internet, fits into the context of political demonstrations occurred in Europe, Middle East, USA and Brazil, between 2010 and 2013. Thus, reflections were made on of the politics transformations in contemporary society, given the course of the current economic and ecological crisis. By means of analyzes of the thinkers of critical theory (Marx, Adorno, Horkheimer, Debord) and New Value Critique (Kurz, Jappe, Trenkle), this study presents a theoretical model that we call paradigm of antipower, which was based work on John Holloway´s work, to understand the oppositional public sphere practiced on the Internet in their tendency to a praxis of direct, open, free and anti-capitalist action.

Internetové pirátství / Internet piracy

Fiala, Jiří January 2012 (has links)
The main objective of this thesis is to describe the Internet piracy phenomenon and to define responsibility of individuals for copyright violations on the Internet from the view of valid Czech legislation. In order to prevent Internet piracy, countries are pushed to swiftly react on continuous development of new technologies used by pirates - these efforts of individual countries are described in several chapters of this thesis that are exploring the most significant court rulings. These rulings have or may eventually have impact on the legislation or approach to the piracy of other countries. This thesis consists of ten chapters. First chapter gives an introduction to the Internet piracy problem. It claims that copyright violation on the Internet might nowadays be the most common unlawful deed. Second chapter provides definitions of three terms which are later frequently used in the thesis. These terms are: work of authorship, Internet, Internet piracy. Third chapter explores copyright and its content (personal and economic rights of the author). Next chapter analyses the legal means of protection of the work of authorship. These means are provided by various areas of law (copyright law, administrative law, criminal law etc.). Fifth chapter explains functioning of peer-to-peer networks which are...
