In an Evolving Threat Landscape, Healthcare IT Security Leaders Face the Growing Challenge of IoT Devices

During a recent webinar hosted by the Center for Connected Medicine, healthcare IT security thought leaders examined the proliferation of internet-connected devices in healthcare and parsed the challenges of cybersecurity and the Internet of Medical Things (IoMT) in an evolving threat environment.

The Center for Connected Medicine is a Pittsburgh-based collaborative health care executive briefing center comprised of five founding partners—GE, IBM, UPMC, Nokia and Lenovo Health. The organization hosted the webinar in an effort to help health system executive leaders better understand the risks and solutions of cybersecurity and IoMT. During the webinar, industry thought leaders explored the threats and how the industry is responding.

“It seems like I read new headlines every day about the latest cyber attack targeting health institutions, many of which have involved IoMT devices,” Rasu Shrestha, M.D., chief innovation officer at UPMC and executive vice president at UPMC Enterprises, who moderated the webinar, said during the presentation.

To get a sense of the current healthcare data security landscape, cyber attacks targeting patient data organizations increased 300 percent from 2014 to 2016, according to a report from TrapX Security. The U.S. healthcare industry is currently spending an estimated $6.2 billion a year in fines and other costs related to health data breaches, reports the Ponemon Institute.

As cyber attacks against the healthcare industry continue to evolve, IoMT devices are becoming a bigger target. Data security leaders at patient care organizations now see the vulnerability of IoMT as a top concern in large part because connected medical devices are proliferating in health care.

“The trend is not slowing down,” Shrestha said, noting that in the first quarter of this year, healthcare faced more cyber attacks than any other industry vertical, citing data from Vectra Networks. “As you can see, we’re in the midst of an unprecedented barrage of cybersecurity attacks. The time to take action is now. The industry has recognized the challenge and is responding.”

At UPMC, Shrestha said, cybersecurity is a recurring board-room agenda item. “Across the country, healthcare leaders are placing a greater emphasis on protecting their networks and intrusion. There is more attention and spending allocated to cybersecurity, but there is more that needs to be done.”

Garrett Hall, research director, cybersecurity and implementation services at Orem, Utah-based KLAS Research, recently co-authored a report on the healthcare security landscape, which entailed speaking to almost 200 healthcare professionals about their cybersecurity program. Only about 16 percent said their security program was fully functional, he said. During the webinar, Hall delved into the report’s findings and his take on the current security landscape.

“As a healthcare industry, we’re behind the times. There are a number of different reasons. One is that with all the technology advancements, there have been a lot of other priorities that have taken the forefront, with EMRs [electronic medical records], population health, and some other really valuable aspects of healthcare technology, and that has pushed cybersecurity to the back burner a little bit. In addition, there is some trouble that providers report to us about finding good cybersecurity resources in healthcare to fill the gaps and to help organizations prepare and respond to attacks.”

Hall noted that, according to KLAS’s research, about 41 percent of providers reported their organizations have dedicated less than 3 percent of the IT budget to cybersecurity.

“It just hasn’t been a top priority for the board. The good news is, we’re starting to see more of an emphasis on cybersecurity, and, I think, the IoMT has really helped to push some things to the forefront because of the potential for real harm to be done through these attacks. We see more organizations trying to get out in front of attacks and be proactive. The bad news, we are behind. The good news, I think we are catching up,” Hall said.

When asked how healthcare provider organizations can prepare for evolving cybersecurity attacks, Hall responded, “We are seeing that one of the most important ways to prepare and stay ahead of evolving attacks is to do an annual risk assessment to identify gaps and weaknesses, and once you understand those gaps, take that and build a security program or security plan that will allow you to take proactive steps to prepare for attacks and detect and respond to attacks, rather than just wait for something to happen and then react to it. With the evolution of attacks, and with the valuable nature of healthcare information, these attacks are not going to go away. These attacks will continue to change, so staying on top of it with risk assessments and a proactive security program and plan, those are the foundations of what providers should be doing to prepare for whatever may be coming.”

In addition, advanced organizations are leveraging detection strategies, such as security information and event management (SIEM), to monitor activity on their networks for proactive detection, and then build incident response plans and policies, Hall said.

Shrestha noted that UPMC, one of the nation’s largest integrated health systems, has 1,400 applications to manage and support and during annual system reviews, IT leaders identify vulnerabilities associated with each application. “In a typical year, we find more than 1 million vulnerabilities across our environment, which are prioritized by risk and resolved. In fact, UPMC identified and remediated over 3,000 instances of ransomware this last year alone. We recognize the challenge of keeping up with the hackers,” he said.
