Center node: "attack graph threat modeling assessment of ambulatory medical devices"
  Abstract: The continued integration of technology into all#R##N#aspects of society stresses the need to identify and#R##N#understand the risk associated with assimilating new#R##N#technologies. This necessity is heightened when#R##N#technology is used for medical purposes like#R##N#ambulatory devices that monitor a patient’s vital signs.#R##N#This integration creates environments that are#R##N#conducive to malicious activities. The potential impact#R##N#presents new challenges for the medical community.#R##N#Hence, this research presents attack graph#R##N#modeling as a viable solution to identifying#R##N#vulnerabilities, assessing risk, and forming mitigation#R##N#strategies to defend ambulatory medical devices from#R##N#attackers. Common and frequent vulnerabilities and#R##N#attack strategies related to the various aspects of#R##N#ambulatory devices, including Bluetooth enabled#R##N#sensors and Android applications are identified in the#R##N#literature. Based on this analysis, this research#R##N#presents an attack graph modeling example on a#R##N#theoretical device that highlights vulnerabilities and#R##N#mitigation strategies to consider when designing#R##N#ambulatory devices with similar components
