Dr. May Wang, CTO of IoT Security at Palo Alto Networks, joins Dave Bittner to discuss their findings detailed in Unit 42's "Know Your Infusion Pump Vulnerabilities and Secure Your Healthcare Organization" research. Unit 42 recently set out to better understand how well hospitals and other healthcare providers are doing in securing smart infusion pumps, which are network-connected devices that deliver medications and fluids to patients. This topic is of critical concern because security lapses in these devices have the potential to put lives at risk or expose sensitive patient data.

Unit 42's discovery of security gaps in three out of four infusion pumps that they reviewed highlights the need for the healthcare industry to redouble efforts to protect against known vulnerabilities, while diligently following best practices for infusion pumps and hospital networks. May walks us through Unit 42's work.
