Imminent National Cyber Strategy May Lean on Offense at the Expense of Defense

Megan Stifel
OT cybersecurity expert Mike Holcomb joins the Nexus Podcast live from S4 Conference in Miami to discuss how state actors may be leveraging hacktivists to target operational technology (OT). Holcomb has delineated these groups in what he calls a Converged Actor Framework that categorizes threat actors by the impact and frequency of their incidents. A converged actor is potentially the riskiest given the potential for high frequency high impact incidents.

Adam Jurgensen, Medical Device Security Engineer at Valley Health Systems, brings us inside the roles and responsibilities of those experts overseeing connected devices inside healthcare organizations. Jurgensen describes the restrictions his role faces when it comes to updating and patching connected medical devices, the gamut of which may run from MRIs, CT, ultrasounds, to patient monitors, and defibrillators. Compensating controls, segmentation, and other cybersecurity strategies are key for keeping devices secure and patients safe in the event of an incident.
