Abstract: In recent years, concerns about the safety and security of critical infrastructures have increased enormously. The se infrastructures can easily become subjects of physical and cyber attacks. In this paper, we propose a software architecture named Security and Protection Architecture for Physical Infrastructures (SPAPI) for the protection of these critical infrastructures and for other non-military uses. SPAPI has hierarchical, loosely coupled, autonomous management modules for authentication, monitoring and the policy-based control of their respective domains. Due to their autonomous design, each management module works independently according to their predefined policies. In this paper we discuss the design and application of SPAPI in the context of a hypothetical chemical process facility.
