A systems-theoretic security model for large scale, complex systems applied to the US air transportation system
Classical risk-based or game-theoretic security models rely on assumptions from reliability theory and rational expectations economics that are not applicable to security threats. Additionally, these models suffer from serious deficiencies when they are applied to software-intensive, …

Active STPA : integration of hazard analysis into a Safety Management System Framework
… hazard analysis tool based on Systems-Theoretic Accident Model and Processes (STAMP). The Active STPA uses data collected during operations, such as Flight Data Monitoring events and voluntary reporting, to identify leading indicators of increasing risk. The events are compared with the STPA. The …
