Towards Zero Trust: The Design and Implementation of a Secure End-Point Device for Remote Working
Kemal Biçakcı, Yusuf Uzunay, Mansoor Khan · 2021
COVID-19 pandemic and lockdowns forced employees across the world to work from home. Remote working has become a necessity rather than a choice. However, in order to meet this increasing demand, the most pressing security concerns of organizations should be addressed. In this paper, we present the design and implementation of ProGun, an end-point device (a USB dongle) for remote working. We present the hardware/software co-design of ProGun, by which most security risks due to lack of physical protection could be mitigated. We also discuss choices we made among many alternatives for user authentication and their security and usability implications in a remote working environment.
