The Challenge of Medical Devices:
Medical devices represent significant exposure and potential vulnerability to healthcare organizations.
There are thousands of medical devices in use even in small medical operations. These devices are generally made to meet a specific use, and not often created with security at top of mind. They are also essential to keep functioning in order for health systems to operate. The volume, use, and design of medical devices combine therefore to present a unique challenge for healthcare security.
So how do you best protect your hospital or health system from the threats posed by unprotected medical devices? We asked our experts, Mark Ferrari, MS, PMP, CISSP, HCISPP, HITRUST Certified Practitioner, and Ryan Patrick, MBA, CISSP, HITRUST Certified Practitioner, for some tips:
Preparedness: Health Organizations need to be prepared for data breaches in their medical devices.
Data breaches should be approached not as a question of if, but of when. Expecting exposure and practicing incident response activities is the most beneficial thing health systems can do for their data’s security. It’s essential to establish a cross-departmental designated CIRT (cyber incident response team) that is responsible for keeping track of potential areas of exposure. It is also important to have formalized governance in place, which includes accurate and timely inventories, change management and configuration management. Adopting a security framework such as NIST or HITRUST will help guide the team’s preparation.
Detection: Organizations need increased risk detection practices and must have a dynamic, automated system for identifying risk in medical devices & the Internet of Things (IoT).
This automated system should have the dynamic capability to identify new devices in your health system environment, their operating systems and patch levels, and consistently compare device behavior to ‘normal behavior’ to detect potential breaches. A complete detection system should include a measurable way to score abnormal behavior in terms of risk, and to isolate devices that are functioning abnormally. Once unusual behavior is detected, the CIRT team will be alerted to begin their incident response plan.
Containment, Eradication, and Recovery: A cross-departmental CIRT should practice incident responses to decrease the damage a breach can do.
When a breach is detected and validated by your incident response team, the question becomes how quickly and thoroughly you can contain the threat, eradicate the danger, and recover any compromised data. We recommend practicing incident response incident response activities on a regular basis to streamline this process. As former military, we are familiar with the army’s use of tabletop activities to establish and practice an efficient response in case of an attack.
Post Activity: Incorporate the lessons learned from a breach into your response plan for future.
As we all know, data breaches will happen, and you need to be prepared when they do. But learning from the breach is important too. It is crucial that the team evaluates where the threat occurred and establish a plan to minimize that risk in future. Investigate the problems you experienced, discuss the lessons learned, and update your plan to include solutions.
