Resiliency Policies in Access Control for Emergency and Disaster Response
Natural or man-made disasters pose a unique challenge, whereby previously defined constraints can potentially debilitate an organizations ability to act. It is difficulty to design access control framework in responding to major emergencies, particularly with respect to the on-site coordination of absent of users. Here, we propose techniques which ensure that user-task assignment is both secure and failure resilient The resiliency checking problem can be mapped into SAT problem, so it can be solved with SAT algorithm. To address the absent of important users, we use delegation mechanism that can respond automatically to the absence of appropriately authorized users. We explore the way in which such a mechanism be used for overriding of policy-based authorization decisions.
