Medical Imaging Device Security: An Exploratory Study
share
Recent years have witnessed a boom of connected medical devices, which brings security issues in the meantime. As an essential category of medical devices, from our observation, medical imaging devices are under enormous potential security risk. To address it, many works have been done, and effective methods were proposed in the past decades. However, it remains to review current medical imaging devices and evaluate the security and privacy of these devices. We first investigate 15 devices (such as X-Ray, DSA, CT, etc.) which vary in manufacturers and functions to have an overview of medical imaging devices, hacking techniques, their protection mechanisms and the threat model. We further analyse them and have confirmed that all of them have more or fewer security defects, some of which can be attacked by a well-trained hacker. Then, we design a list of criteria and define a multi-level hierarchy for both vendors and government agencies to rate the products. At last, some actionable recommendations are given to help developers to protect these devices.
