Resumo

A literatura referente aos ataques físico-cibernéticos em Sistemas de Controle em Rede indica que ataques furtivos e acurados devem ser planejados com base em um conhecimento igualmente acurado sobre o modelo do sistema atacado. Neste contexto, a literatura sobre Sistemas de Controle em Rede reconhece o ataque Ativo de Identificação de Sistemas como uma ferramenta capaz de prover tais modelos ao atacante. No entanto, há uma carência de discussão sobre contramedidas para este ataque específico. Nesse sentido, este trabalho propõe o uso de controladores aleatoriamente chaveados como uma contramedida para o ataque Ativo de Identificação de Sistemas. Os resultados de simulação indicam que esta contramedida é capaz de mitigar o referido ataque e executar, simultaneamente, um controle satisfatório da planta.
