Proteção Cibernética: Uma proposta para aprimorar a segurança dos sistemas digitais da Marinha do Brasil

Abstract

ABSTRACT Cyber protection: A proposal to improve the security of the Brazilian Navy’s digital systems The number of cyber attacks on the digital systems of government and private institutions is growing. This study aimed to present the main software attacks and vulnerabilities that can affect these digital systems. Furthermore, it explored the Navy's cyber defense structure and its cyber operations, and the development and approval processes of digital systems. To achieve the objective of this work, bibliographic research and interviews were used as data collection methods. From the data analysis, it was possible to see that Cyber War exercises are carried out to strengthen the Navy's skills in facing cyber threats. Also, the system development process does not adopt secure development methodologies, thus potentially compromising the Cyber Protection of the Brazilian Navy network. Therefore, this work proposes a solution to improve the development and approval processes of the Brazilian Navy's digital systems, aiming to increase the security of these systems and, therefore, reinforce the Navy's Cyber Protection. Finally, the implementation of this solution needs to be carried out by the Navy's Directorate of Communications and Information Technology, in a gradual and centralized manner, with the support of Military Organizations that develop digital systems.
