This report was authored by TXOne Networks and published in November 2022. It discusses methods for cybersecurity protection of devices in hospitals when they are part of an OT (Operations Technology) network. The first imperative is to separate OT from IT (Information Technology) networks. As noted, IT anti-malware was not designed to protect medical equipment. A challenge is to update older equipment with outdated software that may be too old to upgrade. Methods are being developed to determine which devices can be trusted on an OT network, which devices can be locked down to prevent infection, and which devices need to be cleaned of malware. The security of remote patient monitoring equipment for telemedicine needs to be checked. Cybersecurity threats are summarized in this paper as are OT zero-trust cyber defenses.
