Cybersecurity in Medicine: Safeguarding Class 2 Medical Devices Against Hacking

class 2 medical device security

In the evolving landscape of cybersecurity, the protection of medical devices has emerged as a critical concern. Class 2 medical devices, which include crucial life-saving equipment such as insulin pumps and pacemakers, have unfortunately been susceptible to hacking, posing significant risks to patient safety. In this blog, we’ll explore real-world instances of these vulnerabilities, the proactive measures taken by the FDA, and how Blue Goat Cyber contributes to fortifying these devices against cyber threats.

What Are Class 2 Medical Devices?

In medical equipment, devices are categorized based on their risk to patients. The U.S. Food and Drug Administration (FDA) defines three classes:

  1. Class 1: Devices with the lowest risk. Examples include bandages and handheld surgical instruments.
  2. Class 2: These are higher-risk devices than Class 1, requiring greater regulatory controls to ensure safety and effectiveness. Examples include:
    • Insulin pumps: Used for continuous insulin delivery in diabetes management.
    • Infusion pumps: Used for controlled delivery of medications, nutrients, and fluids.
    • Diagnostic imaging devices: Such as ultrasound and MRI machines.
    • Blood pressure monitors and ventilators.
  3. Class 3: The highest-risk devices that support or sustain human life. These include heart valves and implantable defibrillators.

The Vulnerability of Class 2 Devices

Given their sophistication and connectivity, Class 2 devices, while essential for patient care, can be prone to cyberattacks. Here are a couple of examples that highlight the vulnerabilities and risks:

  1. Insulin Pump Hacking: As previously mentioned, insulin pumps are susceptible to unauthorized remote access, potentially leading to dangerous alterations in insulin delivery.
  2. Infusion Pump Vulnerabilities: In 2015, the FDA issued a safety alert about certain Hospira infusion systems due to cybersecurity vulnerabilities. Hackers could potentially access these devices and modify the dosage the pumps delivered.

The Importance of Cybersecurity in Class 2 Devices

Given these examples, it’s clear that cybersecurity isn’t just a matter of protecting data – it’s about safeguarding human lives. While beneficial for healthcare delivery, the interconnectedness of modern medical devices also opens doors for cyber threats. It’s imperative for manufacturers, healthcare providers, and cybersecurity experts like Blue Goat Cyber to work collaboratively to address these vulnerabilities.

FDA’s Stance and Initiatives

Recognizing the gravity of these threats, the FDA has been actively involved in enhancing medical device security. In 2018, the FDA released a Medical Device Safety Action Plan, emphasizing the importance of cybersecurity in medical devices. This plan includes:

  1. Pre-Market Guidance: Issuing guidance for manufacturers on incorporating cybersecurity protections during the design and development of medical devices.
  2. Post-Market Surveillance: Implementing robust post-market surveillance to identify and address cybersecurity vulnerabilities promptly.
  3. Collaboration: Collaborating with other government agencies and international partners to develop a unified approach to medical device cybersecurity.
  4. Public Awareness: Increasing awareness among stakeholders, including patients, about the importance of cybersecurity in medical devices.

Blue Goat Cyber’s Role

At Blue Goat Cyber, we understand that the security of Class 2 medical devices is about passive defense and proactive offense. This is where Vulnerability Assessment and Penetration Testing (VAPT) become crucial components of our cybersecurity strategy.

What is VAPT?

Vulnerability Assessment (VA) involves systematically reviewing Class 2 medical devices to identify potential security weaknesses. It’s like a health check-up for devices, seeking out vulnerabilities that cybercriminals could exploit.

Penetration Testing (PT) goes a step further. It’s the practice of simulating cyber-attacks on these devices in a controlled environment. This ‘ethical hacking’ approach tests the effectiveness of security measures in place.

Blue Goat Cyber’s Approach to VAPT

  1. Tailored Assessments: Each Class 2 medical device has unique features and functionalities. We customize our vulnerability assessments to accommodate each device’s specific nature and use, ensuring thoroughness and accuracy.
  2. Real-World Attack Simulation: Our penetration tests aren’t just theoretical. We simulate real-world attack scenarios that these devices might face. This approach helps understand how a device would withstand an actual cyber threat.
  3. Compliance with FDA Guidelines: We align our VAPT procedures with the latest FDA cybersecurity guidelines for medical devices. This ensures not just security but also regulatory compliance.
  4. Reporting and Remediation: Post-VAPT, we provide detailed reports outlining vulnerabilities and potential impacts. More importantly, we don’t just stop at identifying problems; we offer solutions. This involves developing remediation strategies to address the identified vulnerabilities.
  5. Continuous Monitoring and Re-Assessment: Cyber threats evolve, and so do our strategies. We offer ongoing monitoring and periodic reassessment of the devices to ensure they remain secure against new and emerging threats.
  6. Collaboration with Manufacturers and Healthcare Providers: Our work involves close collaboration with device manufacturers and healthcare providers. We believe in a unified approach, where information and strategies are shared to enhance security.


In conclusion, while Class 2 medical devices are pivotal in patient care, their cybersecurity is a paramount concern that requires concerted efforts from all stakeholders. Blue Goat Cyber is at the forefront, offering specialized expertise to secure these devices against cyber threats, ultimately contributing to safer healthcare delivery.

Remember, in healthcare, cybersecurity is not just about protecting information; it’s about protecting lives. Stay tuned to Blue Goat Cyber for more insights and updates on the evolving landscape of medical device cybersecurity.
