摘要: Access control (AC) is one of the most fundamental and widely used requirements for privacy security. Given a subject's access request on resource in system, AC determines whether this permitted or denied based policies (ACPs). This position paper introduces our approach to ensure correctness using verification. More specifically, given model an ACP, detects inconsistencies between models, specifications, expected behaviors AC. Such represent faults (in ACP), which we target at detecting before ACP deployment.
