That's a concern also expressed by Chris Sherman (left), an analyst serving security and risk professionals at Cambridge, Mass.-based Forrester Research. He says hospitals typically have multiple VLANs. Usually a traditional IT network is where medical records reside, he explains. And sometimes there is a separate network for bioengineering or a vendor-specific network for branded medical systems. Complicating the security challenge is complexity at the operating system level. “In traditional IT, you might have to deal with, at most, a few operating systems,” he says. “With clinical engineering, you could have 100 different vendors, many different operating systems and with multiple levels of access control and security vulnerability. So, security is really an operational challenge.”Sherman says IT does not have a lot of alignment with clinical engineering activities, so security, especially when most of the devices are not managed by IT, is often left up to the vendor. “That means you can't really apply things like whitelisting and sandboxing and endpoint visibility control, anti-malware or anti-virus,” he says. Two developments may help. One is a frequently referenced risk framework, IEC 80001-1:2010, application of risk management for IT-networks incorporating medical devices. “The industry is now trying to extend that ecosystem to include mobile health devices,” Sherman explains. The other development is from the FDA. Until recently, he says, the FDA was focused mostly on pre-market guidance for medical device-makers – namely the things you should include in a design to make it more secure. Recently, though, the FDA radically shifted to a lifecycle approach that recognizes the need to address care, maintenance and updates in the field. Clarity from the FDAFor years, medical providers have petitioned the FDA to clarify the rules around cybersecurity and medical devices, says Mike Meikle, CEO of the Hawkthorne Group, a Richmond, Va.-based boutique management and information technology consulting firm. For instance, he notes, device manufacturers often believed they had to re-certify every time they applied an operating system patch or installed endpoint protection. The issue gained more urgency as HIPAA penalties for patient data breaches became more common. The FDA began to provide some clarity for these concerns with its October 2014 release of a guidance document on medical device cybersecurity. Since then, the FDA's approach has evolved with some of that thinking embodied in a workshop and newly published draft guidance in January 2016.
According to Katie Moussouris (left), chief policy officer at HackerOne, a San Francisco-based vulnerability coordination and bug bounty platform, one of the most persistent myths in the industry is that the FDA doesn't act “until the bodies start piling up.” In fact, in recent years they have been operating well ahead of any actual harm, she says.“The goal of proactively addressing cybersecurity risks throughout a medical device's full product lifecycle is simple: to keep patients safe,” explains Suzanne Schwartz, associate director for science and strategic partnerships and acting director of emergency preparedness/operations and medical countermeasures in the FDA's Center for Devices and Radiological Health. While building cybersecurity safeguards into the development and design of a medical device is essential in demonstrating the safety and effectiveness of the product, it doesn't end there, she says. In fact, once devices are on the market, new vulnerabilities can be introduced, “so we need to ensure mechanisms are in place to monitor, identify and address these issues to keep patients safe and protect the public health,” says Schwartz.Getting there has been a slow and laborious process. The FDA has been working with its stakeholders to address medical device cybersecurity for several years, she says. “This is the new reality today: Hospitals and health care systems are under constant attempts at attack and intrusion of their networks,” says Schwartz. Therefore, protection of these systems, which contain highly sought-after personal health information and personal identity information, means that medical devices need to be better secured as well.Now, Schwartz says the FDA is looking to all stakeholders – manufacturers, researchers, government and health care delivery organizations – to work together to collaboratively share information and assess cybersecurity risk “in a trusted and open setting” in order to better address device safety. This is a culture shift and will take a change in attitude and effort, Schwartz expects to see more and more open collaboration among these groups because, she says, she has experienced first-hand the positive effects this shared responsibility has on addressing cybersecurity vulnerabilities before they cause patient harm.Value of data
Russell Jones (left), partner in Deloitte's cyber risk services group (and its resident expert on cybersecurity and medical devices), advises on the FDA cybersecurity guidance. “As far as the FDA guidance goes, it is pretty robust,” he says. Jones contrasts the 2014 guidance, which focused on premarket steps, with the new lifecycle approach that is the focus in 2016. “The FDA is now recommending device manufacturers to follow each device to the end of its life and understand how to support it from a security standpoint,” he explains. Ultimately, though, better across-the-board protection for medical information will require that the value of the data must be understood, says Eric Chiu, president and co-founder of HyTrust, a cloud-focused control and security company. “It's often hard to pursue protection of that which has no perceived value,” he says. “The value of medical data is not as clearly understood as of now, and we're relying on regulations like HIPAA to drive compliance to policies that better protect medical data.”Chiu says when personal or financial information is stolen, people may have to get a new card, make some calls or do some level of repair to their identity and credit, all of which are considered inconveniences. However, if medical devices and the information they use during treatments are compromised, the consequence becomes more than just an inconvenience; it may mean loss of life or significant harm to patients, he notes.Fortunately, many of the same practices that we're familiar with today to reduce risk and protect information can be applied, he says, namely working to identify, test and remove device vulnerabilities during development. Then, ongoing assessment must continue as these tools are deployed, giving consideration to how devices are connected to networks, what devices, people and applications are able to access, and protecting information on devices and in applications by something as simple as encrypting the information.
Finally, notes Jovan Miladinovic (left), acting CISO at Toronto Public Health, the challenges are not unmanagemeable, but “people need to do their homework.” In his view, security processes and technologies have not evolved as much in the last 20 year as the threat. “New technology is coming faster than the governance we need,” he says.When it comes to medical information, Miladinovic laments the excessive caution of some organizations. “There are great applications being developed but they are sometimes not deployed because a chief privacy officer vetoes them,” he says. “The role of privacy and security pros is to assess the risks rather than to simply have knee-jerk reactions.”
