IoT Security Ensures a Healthier Security Posture
BayCare Health System is a major not-for-profit healthcare provider serving patients across the Tampa Bay and West Central Florida regions. As one of the largest private employers in the area, BayCare not only delivers outstanding medical care to its patients and the community but also provides an estimated $6.62 billion in annual impact on the state economy. Protecting BayCare from attacks helps bolster both the physical and financial health of the region.
BayCare’s security team understands that in healthcare, downtime simply isn’t an option. To provide consistent, excellent care, they must secure patient information and maintain patient privacy while also protecting the entire organization from cyberattacks, ransomware, and system interruptions. This requires them to secure a growing number of networked medical devices typically running on unpatchable legacy systems.
SECURING TRADITIONALLY UNSECURED MEDICAL IOT DEVICES CALLS FOR A NEW APPROACH
Specialized medical devices often run on older or outdated operating systems, and they usually go unpatched due to the need for FDA validation and certification. In fact, according to Unit 42 research, 83% of medical imaging devices ran on unsupported operating systems in 2019—a 56% increase from 2018. Legacy antivirus and other traditional security solutions often interfere with these devices, potentially disrupting patient care. Furthermore, the machines are networked together to deliver relevant information to providers across the BayCare system, compounding the risk to the organization.
Ralph Oliva, BayCare’s manager of medical device integration and security, knew these medical devices needed to be protected and that he and his team needed visibility into how the machines were communicating with the outside world. He also knew BayCare wasn’t alone in needing to protect unsecured medical devices—it was a problem that had plagued medical systems for years. When talking about their challenges protecting their growing array of medical devices, he shared, “This isn’t a BayCare problem. It’s an industry problem.”
Like so many modern healthcare providers, BayCare needed a security solution that could identify and protect all its unsecured devices, no matter what they were, where they were, or what operating system they used. Oliva and his team were looking for a state-of-the-art system that was:
- Agentless and passive
- Device manufacturer- and operating system-agnostic
- Able to monitor all of the organization’s medical and IoT devices
PALO ALTO NETWORKS IOT SECURITY SPEEDS UP PREVENTION
BayCare identified Zingbox IoT Guardian—now Palo Alto Networks IoT Security—as a security solution that looked to offer exactly what they needed. The team quickly set up a proof of concept (POC) at one of their hospitals to determine the effectiveness of the new technology.
“Within hours of deployment, we discovered and identified thousands of devices, including a few that gave us critical insight, allowing us to take action and implement preventive measures,” Oliva says. “We now receive alerts on various activities which were simply not visible before we implemented this solution.”
Based on this success, BayCare’s information security executive team quickly approved the rollout of the solution to all 15 of its hospitals. Based on the success of the POC, BayCare’s information security VP and chief technology officer Scott Patterson challenged Oliva to see if his team could implement the solution across the system even more quickly than the planned three-month rollout. Oliva and his team had it up and running in all BayCare’s hospitals in just three weeks.
BETTER INSIGHT AND VISIBILITY LEAD TO BETTER PROTECTION
BayCare now uses Palo Alto Networks IoT Security to monitor all IoT and IoMT devices across its environment. After deployment, BayCare received numerous alerts on how the medical devices were behaving. Additionally, BayCare now has insight on medical device usage and the ability to capture that data for utilization analytics reporting. IoT Security has fundamentally changed BayCare’s security posture. “Without it, we simply would not have known about these types of behaviors,” Oliva says.
CONSTANT MONITORING ENABLES QUICKER, MORE TARGETED RESPONSES
Today, if one of BayCare’s devices starts acting outside of its normal behavior, Oliva and his team get notified by text and email as well as on their dashboard and can respond immediately. The BayCare Security & Network Operation Center also actively monitors these same alerts 24/7. To combat alert fatigue and noise, IoT Security categorizes the threats it uncovers and highlights critical ones so the team knows to address them right away. BayCare now uses IoT Security to monitor more than 33,000 devices.
A Cure for an Industry-Wide Problem
Vulnerable medical devices have troubled the entire healthcare sector for too long. With the valuable patient data they hold, healthcare organizations have been subject to an increasing number of attacks.
BayCare used to struggle to secure the ever-growing number of medical and IoT devices across its network. Happily for Ralph Oliva and his security team, Palo Alto Networks IoT Security has finally filled this dangerous vulnerability gap.
