Direito internacional e ciberguerra: ataques cibernéticos entre nações, manual de Tallinn, por que é mais fácil regular uma ciberguerra do que regular uma cibersegurança? 49 f. Trabalho de Conclusão de Curso (Graduação) - Unidade Acadêmica Especial de Ciências Sociais Aplicadas, Universidade Federal de Goiás, Cidade de Goiás, 2021.http://repositorio.bc.ufg.br//handle/ri/19795This monograph aims to detect how cyberwar has been growing and becoming more and more present in daily life, occupying a gap left by Public International Law, while we do not have international cybersecurity and we still face issues of sovereignty and ways of identifying those responsible for cyber-attacks. Thus, the research analyzes the limitations of sovereignty and accountability faced by the Law and how it leads to a lack of control in cyberspace, taking a turn towards cyberwar, which already has a possible regulation already ready, the Tallinn Manual. Starting from deductive and case studies methods, the historical evolution of sovereignty, concepts of cyberwar, cyberspace and cybersecurity were analyzed, as well elements to characterize international accountability and its difficulties. Through bibliographic review of doctrines, manuals and articles related to the theme, study of the Tallinn Manual and analysis of concrete cases of cyberwar, we seek to promote a study that lists the causes of the difficulties of international cybersecurity. Although we found a good example in cybersecurity cooperation throughout the research, we still seem closer to regulating a cyberwar than having internationally coordinated cybersecurity.porAcesso AbertoCiberguerraCibersegurançaCiberespaçoCiberataqueManual de tallinnCyberwarCybersecurityCyberspaceCyber-attackTallinn manualTCC
