Hospitals that need to make better network security should carefully approach the hundreds of medical devices or tools they are utilizing, involving fetal monitors, electrocardiographs, medical imaging devices, lasers and gamma cameras, to name a few.
Few medical devices hold a sizable rate of information that can be hacked; others do not have much information, but can increase network susceptibility. Infusion pumps, for example, do not have a lot of information but are a doorway to the network and “have become the poster kid for medical device security gone incorrect,” claims Stephanie Domas, an ethical hacker and lead medical device security engineer at Battelle, a huge research and development agency.
Infusion pumps aren’t made for security, and their susceptibilities are famous to researchers, who can conveniently purchase a latest device and assess its level of security.
For years, researchers have been attempting to work with medical devices' manufacturers to make better the security of latest devices being manufactured, mostly without much success, Domas states. But that is initiating to change.
The breakthrough came when researchers issued reports on infusion pump susceptibilities, specifically the Hospira Symbiq Infusion System, and then the Food and Drug Administration warned consumers of the Hospira Symbiq to important cybersecurity susceptibilities and suggested discontinuing utilization of the pumps.
Hospira learned to actively react to researchers, Domas claims, and there is increasing cooperation among manufactures and researchers, with certain researchers having approach to devices under development to reverse engineer and seek for mistakes without running afoul of the Digital Millennium Copyright Act.
Manufacturers also growingly are setting up processes to accept data from outsiders who’ve found susceptibilities in medical devices.
Hospitals themselves mostly are to blame for worse device security, Domas contends, with poor patch management. Services utilize a broad range of devices, which mostly require security patches, and the increased complication is an investing factor to increased susceptibility.
Hospitals are not attempting to be lax about security, but the very number of tools makes it complicated. “They first require knowing where all the equipment is,” she states. “It is actually hard to track what is present and where it is, and to track patching.”
The industry also has several third-party medical device resellers, so a hospital might not have a straight contact to a manufacturer, which might not even know that a hospital purchased its products.
When contributors do purchase medical devices from the manufacturer, they should thoroughly specify the security and safety needs that they hope a device to have, Domas counsels. The Mayo Clinic, for example, has a list of hopes for vendors to meet before making a purchase. More of that can actually assist to drive the industry toward safer and better tools, she adds.
“Both sides are actually attempting to get better. The top objectives for contributors are patient care and safety. But there is a deficiency of great security talent for manufacturers to hire.”
