Why TARA Matters in Medical Devices

Why TARA Matters in Medical Devices

As industries quickly move toward digital technology, cybersecurity is no longer optional; it’s essential.

Automotive and medical device industries share the same high-stakes goals:

✔ Protecting lives

✔ Securing data

✔ Keeping systems reliable

✔ Avoiding costly failures

But the way they handle cybersecurity—and the challenges they face—are very different.

I work with TARA every day in the automotive industry. I’ve seen how structured cybersecurity assessments do much more than meet regulations. They help find hidden risks early, guide better design decisions, and most importantly, save lives.

Medical devices are becoming more connected, more complex—and unfortunately, more vulnerable. Yet when I talk to people outside the automotive field, I often hear:

“We don’t really do TARA. We do some risk assessment, but not like you do for vehicles.”

That’s a missed opportunity. In the automotive world, we’ve improved TARA to cover safety, system function, data privacy, and financial risk throughout the entire product lifecycle. I believe the healthcare industry can benefit from the same clear, structured, and proactive approach.

Automotive vs. Medical Device Cybersecurity

Let me show you what I mean. Here’s a quick comparison of how cybersecurity risks are handled in the automotive and medical device industries:

Now, let’s see how TARA can help in the medical device space.

It starts by understanding what the device does, who uses it, and how it connects to other systems.

Then, we identify possible threats—like patient harm, data leaks, or system misuse.

After that, we evaluate how likely and how serious each risk is.

Finally, we apply the right controls and keep monitoring to make sure the device stays safe over time.

Real-World Example: ECG Device & Mobile App Breach

Here’s how TARA could have helped prevent a real-world security incident.

A wearable ECG device sent data to a mobile app. The app's API had no rate limiting or authentication. An attacker exploited this and accessed sensitive health records from multiple patients.
