Infraestruturas críticas e ameaças cibernéticas: uma análise da cibersegurança dos cabos submarinos brasileiros

Abstract

Since February 2022, the conflict between Russia and Ukraine has highlighted the strategic relevance of cybersecurity in critical infrastructures in contemporary conflicts, highlighting the global consequences of cyber actions. Critical infrastructure, particularly submarine cables, plays a key role in global connectivity and digital communication. In the Brazilian scenario, the cyber protection of these cables is essential to preserve the integrity of national communications and protect confidential information. This essay analyzes the relevance of cybersecurity in Brazil's submarine cables, considering the associated vulnerabilities and the main cyber threats in cyberspace. The paper includes an analysis of current cybersecurity policies for critical infrastructures, focusing on Brazil's submarine cables, and suggests actions to mitigate possible cyberattacks on these critical infrastructures. The analysis indicates that, although Brazil has a robust submarine cable infrastructure, constant investment in cybersecurity is essential to reduce the dangers of attacks, whether physical or digital. The importance of this study lies in the urgent need to address communication vulnerabilities in an increasingly interconnected world, highlighting the importance of a regulatory framework and solid security practices.
