Cyber Security Threat Modeling of A Telesurgery System

摘要

Telesurgery allows surgeons to perform surgery on patients remotely with the advancement of surgical robots and network communication technologies. But there are potential issues such as communication latency and cyber security. Researchers found that the use of fifth generation of mobile communication technologies (5G) is a radical change in reducing latency. However, cyber security to protect the telesurgery system from the attackers is still an open issue. In this paper, we have derived a telesurgery system consisting of components, their workflows, and interactions. After that, the Microsoft threat modeling method called STRIDE has been applied to identify and enumerate threats. The resultant threats detail may help to apply appropriate safeguards for the improvement of cyber security in the telesurgery system. Moreover, several defense mechanisms are provided at the end.
