Cyberattacks in Connected Healthcare: 3 Actions to Protect Your Devices

In today's digital healthcare era, the threat of cyberattacks on connected medical devices is escalating. Recent cyberattacks in connected healthcare highlight the vulnerability of devices like pacemakers and insulin pumps to hacking, posing significant health risks. This growing concern underscores the need for rigorous cybersecurity protocols. The medical community, including manufacturers and healthcare professionals, must collaborate closely, guided by regulatory bodies like the FDA, to fortify defenses against these cyber threats. Ensuring patient safety in this interconnected landscape is a shared responsibility, demanding continuous vigilance and adaptive strategies.

In 2017, a software vulnerability in pacemakers forced a massive recall, putting 465,000 patients at risk. Hackers could have exploited this flaw to drain the battery or alter the pacing rate, potentially causing heart failure or death.

More recently, older model insulin pumps were found to have a chink in their cyber armor, allowing unauthorized access and manipulation of insulin delivery. This could lead to dangerous highs or lows in blood sugar, putting diabetics in immediate danger.

These are just a glimpse of the reality we face with the growing reliance on connected medical devices. Here are three key actions you can take to stay ahead of the curve and protect yourself from cyberattacks on your health:

1. Team Up with an Information Sharing Analysis Organization (ISAO)

Think of ISAOs as neighborhood watch programs for the medical device world. These organizations gather and share intel on cyber threats specific to medical devices, keeping you informed and prepared. Joining an ISAO like the National Health Information Sharing & Analysis Center (NH-ISAC) gives you access to real-time threat alerts, vulnerability reports, and expert guidance – all crucial for staying ahead of the hackers.

2. Befriend Your Risk Management Framework (and Give it a Cybersecurity Makeover)

Remember that trusty risk management plan you already have in place for your medical device? It's time to give it a cybersecurity upgrade. Existing frameworks like ISO 14971 can be adapted to identify and address cyber vulnerabilities. Think of it like installing a digital shield around your device, making it tougher for hackers to breach.

3. Embrace the Art of Continuous Learning and Adaptation

Cybersecurity is a game of cat and mouse, and the bad guys are constantly innovating. To stay ahead, you need to be a quick learner and a nimble adapter. This means:

• Moving from passive monitoring to proactive vulnerability detection: Don't wait for the attack, hunt down the weaknesses before they're exploited.
• Having open conversations about product life cycles and obsolescence: Sometimes, the best defense is a good offense. If a device can't be adequately secured, consider retiring it before it becomes a ticking time bomb.
• Leveraging tools like the Common Vulnerability Scoring System (CVSS): This handy tool assigns severity scores to vulnerabilities, helping you prioritize your patching efforts and focus on the most critical threats.

By taking these steps, we can work together to create a safer future for the millions of people who rely on medical devices every day. Remember, cybersecurity is a shared responsibility, and each of us has a role to play in protecting our health from the invisible dangers lurking in the digital shadows.
