Sistemas Operacionais: Implementação e Segurança de Arquivos via Arquitetura de I-nodes e ACLs

Abstract

Este artigo analisa a implementação e a segurança em sistemas de arquivos, abordandoa transição entre o armazenamento físico e a visualização lógica de dados. O problema centralreside na necessidade de garantir o equilíbrio entre velocidade de acesso, aproveitamentode espaço e proteção contra falhas catastróficas. O objetivo é validar a eficiência da arquiteturade I-nodes e o uso de Mapas de Bits para gerenciamento de disco. A metodologia utilizasimulações em ambiente Python no Google Colab para testar algoritmos de alocação e Listasde Controle de Acesso (ACLs). Os resultados demonstram que a separação de metadados viaI-nodes e a implementação de permissões granulares asseguram a integridade lógica e a escalabilidadedo sistema.
