In this work, researchers addressed assurance challenges in the context of distributed real-time systems (DRTS) by creating tools and techniques to

• express enforceable policies in multiple domains, including logical and timing correctness
• verify correctness of an enforcer implementation against its policy
• combine multiple enforcers and resolve any inconsistencies between their behavior
• verify that enforcers across multiple nodes of DRTS implement a global safety policy
• deploy enforcers so that they cannot be circumvented by a well-defined attacker (i.e., has control of at least one monitored component)
• verify that the enforcers react on time to prevent physical consequences (e.g., aircraft crash)
