Alarms are essential for medical systems in order to ensure patient safety during deteriorating clinical situations and inevitable device malfunction. As medical devices are connected together to become interoperable, alarms become crucial part in making them high-assurance, in nature. Traditional alarm systems for interoperable medical devices have been patient-centric. In this paper, we introduce...
The concept of "system of systems" architecture is increasingly prevalent in many critical domains. Such systems allow information to be pulled from a variety of sources, analyzed to discover correlations and trends, stored to enable real-time and post-hoc assessment, mined to better inform decision-making, and leveraged to automate control of system units. In contrast, medical devices typically...
Interoperable medical devices (IMDs) face threats due to the increased attack surface presented by interoperability and the corresponding infrastructure. Introducing networking and coordination functionalities fundamentally alters medical systems' security properties. Understanding the threats is an important first step in eventually designing security solutions for such systems. Part 1 of this two-part...

Patient-controlled analgesia (PCA) treatment for post-operative pain management is commonly employed in hospitals and its usage is steadily increasing. However, despite the apparent "inherent" safety strategy of requiring active participation of the patient to administer each opioid dose, adverse drug events have been reported. The major reasons for the adverse events are factors such as...
