Desafios midiáticos digitais contemporâneos: um estudo da Ciência das Redes como contribuição ao Ministério da Defesa do Brasil sobre as aplicações do terrorismo peer-to-peer

Abstract

This study aims to understand and enhance Brazil's defense strategies against digital terrorism threats in peer-to-peer (P2P) environments through the application of network science principles. The research investigates the dynamics of digital media and their influence on radicalization, adopting an interdisciplinary approach that integrates concepts from security, communication, international relations, and technology. By conducting an in-depth analysis of the properties of complex networks, focusing on decentralization, capillarity, and self-organization, the work characterizes the structures of these networks and their impact on forming extremist communities and disseminating ideological narratives that support terrorist actions. Furthermore, international case studies of P2P terrorist operations are examined to identify patterns, vulnerabilities, and coordination strategies employed by decentralized groups. Based on a comprehensive theoretical review and a documentary analysis of cyber actions, the research develops predictive scenarios to anticipate potential attacks and inform national security policies. The central hypothesis asserts that the systematic application of network science principles, combined with an in-depth analysis of digital media dynamics, can not only improve the protection and resilience of Brazil's critical infrastructures but also transform how defense institutions respond to rapidly evolving threats. Ultimately, this work contributes to the development of more effective digital defense strategies aligned with new power configurations in the cyber environment, fostering a safer, more resilient, and sovereign digital landscape.
