Empowered Patient Podcast Hospital Network Security Challenges and Strengthening Resilience with Bob Zemke Extreme Networks
Bob Zemke, Director at Extreme Networks, provides network infrastructure and security solutions to help hospitals build resilient and secure networks. Critical security challenges hospitals face in managing networks include the proliferation of connected devices and the vulnerability of medical devices to cyber threats. In addition to education and collaboration between stakeholders, strategies for reducing security risks include network segmentation, AI-powered monitoring, and behavior analysis to help hospitals proactively address possible threats.
Bob explains, "There are multiple factors that we take into play. First, how do we build a resilient network that can handle the amount of devices and traffic types? How do we prioritize the type of traffic flowing through, like the wires of the infrastructure and the wireless connectivity? And then how do we understand through analytics the behavior of those applications so that the healthcare organization, the security team can understand what is standard traffic or potentially rogue behaviors or traffic? What is performance impacting? So, visibility becomes just as important as the segmentation of device types and users on a network."
"It's a security and performance risk. And if you think back to guest WiFi, when we started designing this about 20 years ago, we always laughed. It was like, well, we're building it, but how many people will bring a laptop into a hospital and want to connect as a guest user? Or even how many wireless devices compared to wired would be in a hospital network. Fast forward 20 years, you now have more mobile or wireless connected devices than wired in a given hospital network. So, you have to deal with RF performance management and security. And then you have the personal devices, which again, now with the mobile phone, people expect it."
