• Resumo

• Complex systems face increasing cybersecurity threats that traditional analysis methods fail to address. This paper proposes a methodological framework that integrates the Architecture Analysis & Design Integrated Approach (ARCADIA) method with the System-Theoretic Process Analysis (STPA) for systemic security analysis. We demonstrate the framework's application through a case study in a real-world system for aerospace simulation. The Loss Scenario Table shows that this synergistic approach effectively identifies four emergent vulnerabilities arising from only one unsafe interactions between components, enabling the implementation of Security by Design principles by linking identified Safety Constraints to architectural elements.
