While the FDA has addressed threats to networked medical devices through its guidance and product evaluations, the agency should take more steps to fully integrate cybersecurity into its premarket reviews, according to an HHS report.

The HHS inspector general’s office recommended (PDF) the FDA and manufacturers use presubmission meetings to better address cybersecurity-related questions, and that the agency include cybersecurity as an element in its SMART template used in 510(k) submissions.

In addition, the office urged the agency to begin requiring cybersecurity documentation elements on its refuse-to-accept checklists. The FDA said it concurred with all three of HHS’ recommendations and has begun taking steps to implement them.

“Cybersecurity threats to networked medical devices are on the rise,” the inspector general’s office wrote. “Researchers and hackers have demonstrated that the lack of security controls in these devices makes them vulnerable to cybersecurity attacks, such as ransomware and unauthorized remote access. Such attacks can affect not only a single patient but can also impact a hospital system and disrupt the delivery of healthcare.”

Currently, the agency uses its 2014 guidance (PDF) to conduct its reviews of premarket applications and cybersecurity documentation submissions, including descriptions of a device’s cybersecurity risks, controls to mitigate those risks and lists of the threats considered by the manufacturer.

FDA reviewers take that information, as well as previously known cybersecurity threats, and apply them across their reviews of devices with similar profiles—such as threats that may affect a class of cardiac devices produced by different manufacturers, for example.

The agency often requests additional information and cybersecurity documentation from manufacturers with submissions, HHS said, following its review, and the FDA almost always clears or approves the cybersecurity aspect of networked medical devices following manufacturers’ responses.

However, the 510(k) review template currently does not prompt staff with specific questions, and it lacks a space dedicated for the results of a cybersecurity review, the report said, though the template has included a section on cybersecurity since September 2016.

For the agency’s refuse-to-accept checklist, the FDA plans to include cybersecurity requirements during its next update, after which manufacturer submissions may be turned away for lacking the necessary documentation.
