Defesa cibernética:proposta de estrutura para o âmbito da MB: defesa dos sistemas ciber-físicos dos meios operativos de superfície da MB

Abstract

This work aims to highlight potential vulnerabilities in cyber-physical systems in use in the Brazilian Navy surface ships and then propose a way of reducing these same vulnerabilities. For this it analysis a series of incidents in cyber-physical systems that were triggered by actions initiated in the cyber environment, and have generated various kinetic effects on their physical processes under their control. Its relevance stems from the lack, at present, of any systemic tool in Brazilian Navy able to minimize the unwanted effects of adverse actions against cyber-physical systems in use in the operating surface means. In the literature are reviewed the concepts and practices related to the protection of cyber-physical systems, already published in several international standards for industrial control systems. From this, it is proposed to use them in a structure that will serve to enhance the protection of this type of systems currently used in surface ships in the navy. This structure is formed by an implementation program based on concepts and revised practices and procedures already established in the Navy and applicable in this new domain. The solutions indicate a path to the issue of protection of cyber-physical systems used in surface ships, improving their protection and creating a vision of higher level of risk to the discharge of their duties.
