The availability of wireless interfaces with the new generation medical devices has spawned numerous opportunities in providing better healthcare support to patients. However, the weaknesses of available wireless communication channels introduce various novel attacks on the medical devices. Since the smart mobile devices, such as smartphones, tablets, laptops are also equipped with the same communication channels (WiFi/Bluetooth), attacks on medical devices can be initiated from a compromised or malware infected mobile device. Attackers can steal confidential medical records from a wireless-enabled medical device. Medical devices or communication channels can also be compromised to feed incorrect medical records to doctors or send life threatening commands to the devices. Moreover, since the compromised mobile devices are already inside the security perimeter of a healthcare network, it is very challenging to block attacks from such compromised mobile devices. In this paper, we systematically analyze the novel threats on healthcare devices and networks, which can be initiated from compromised mobile devices. We provide a detail audit guideline to evaluate the security strength of a healthcare network. Based on our proposed guideline, we evaluate the current security state of a large university healthcare facility. We also propose several mitigation strategies to mitigate some of the possible attacks.
