The CISO's Guide to Connected Medical Device Security
Every new insulin pump, pacemaker, and glucose meter connected to your network improves patient care. But it also creates a new entry point for cyberattacks. The sheer volume of these devices can stretch even the most talented IT teams thin. This isn't about their skill; it's about the scale of the challenge. You need a clear strategy for connected medical device security. This guide offers practical steps for improving medical device security, exploring how specialized cybersecurity solutions for medical devices can support your team and protect your patients.
While the Food and Drug Administration (FDA) works to protect medical devices against cyber-attacks along with manufacturers, healthcare providers and patients, these risks are still all too likely. A recent report from Ponemon perceived that cybersecurity risk among medical Internet of Things (IoT) devices was very high, with only 21% of respondents reporting a mature stage of proactive security solutions.
An MSSP can assist your organization with various aspects of security management, compliance and prevention.
What is an MSSP (and Why Does Your Practice Need One)?
A managed security service provider (MSSP) delivers IT security services including threat management, vulnerability management, penetration testing, risk analysis, incident response and more. An MSSP can help organizations detect and prevent cyber-attacks before they occur, or respond to an incident swiftly to minimize the damage.
They also provide regulatory compliance guidance to organizations within the healthcare sector, which need to strictly comply with regulations such as HIPAA and ISO 27001.
Are Your Connected Medical Devices Vulnerable to Attack?
Cyber-attacks can take many forms, including malware, hacking, phishing, spamming, DDOS attacks and other methods. These attacks can affect any device connected to the internet, which includes many medical devices. These devices, such as IV pumps, blood glucose meters, and ventilators, are often used by physicians, nurses, and patients at home.
A cyber-attack can compromise connected medical devices by disrupting their normal function. This can lead to life-threatening situations, such as malfunctioning pacemakers or insulin pumps. When medical devices are connected to the internet, there is a risk that malicious actors will be able to access data stored on them, or even inject malicious code into these devices, which could lead to serious consequences.
The Scale of the Security Problem in Numbers
The challenge isn't just theoretical; it's a rapidly expanding reality. With the market for smart medical devices projected to hit over $125.5 billion by 2033, the number of potential entry points for attackers is growing exponentially. This growth is outpacing security measures, as a staggering 53% of connected medical devices in hospitals have known vulnerabilities. To make matters worse, the average device isn't just flawed in one way—it has an average of 6.2 security weaknesses. This creates a massive attack surface that can easily overwhelm internal IT teams, making a robust, specialized cybersecurity strategy more critical than ever to protect patient data and operational integrity.
The Dangers of Legacy and Outdated Devices
One of the biggest headaches for any IT leader in healthcare is the fleet of legacy devices that are still critical to patient care. Many of these older medical devices and their software simply can't be updated, leaving them permanently exposed and turning them into low-hanging fruit for hackers. This isn't a minor issue. In critical departments like oncology and labs, half of the endpoints are running on old software that no longer receives security patches. An attack on these devices isn't just a data breach; it can directly disrupt patient care and threaten safety. Effectively managing this risk requires a proactive approach to IT management that can isolate, monitor, and protect these vulnerable but essential assets.
The High Stakes of a Medical Device Breach
When a medical device is compromised, the consequences extend far beyond a simple IT ticket. The ripple effects can impact patient safety, data integrity, and the very foundation of your organization's reputation. Understanding these interconnected risks is the first step toward building a more resilient security posture. A breach isn't just a technical failure; it's a critical event that can disrupt care, expose sensitive information, and erode the trust you've worked so hard to build with your patients and community. It requires a comprehensive strategy that addresses not only the technology but also the people and processes that rely on it.
Risks to Patient Safety and Care Delivery
Connected medical devices are fundamental to modern diagnosis, monitoring, and treatment, but their integration into hospital networks creates significant vulnerabilities. When these devices are attacked, the risk is no longer just about data; it's about patient safety. A compromised infusion pump could be manipulated to deliver an incorrect dose, or a connected pacemaker could be disabled, leading to immediate and life-threatening harm. These scenarios disrupt the delivery of care and place patients in direct danger. Ensuring the operational integrity of these devices requires continuous monitoring and a rapid response framework, which is why a robust cybersecurity strategy is non-negotiable in a clinical setting.
Exposure of Sensitive Patient Data
Beyond the immediate physical risks, compromised medical devices serve as a gateway for hackers to access vast amounts of sensitive information. Medical databases are a treasure trove of personal, financial, and insurance details that are highly valuable on the black market. A breach can lead to widespread privacy violations, triggering steep regulatory fines under frameworks like HIPAA and inviting costly lawsuits from affected patients. For IT leaders, this represents a massive compliance and financial risk. Protecting this data requires more than just a firewall; it demands a multi-layered security approach that can detect and neutralize threats before they lead to a catastrophic data leak.
Reputational and Operational Damage
A cyberattack can cause severe and lasting damage to a healthcare organization's reputation. Trust is the cornerstone of the patient-provider relationship, and once it's broken, it is incredibly difficult to repair. News of a breach can make current and potential patients question the safety and reliability of your services. Operationally, the fallout is just as damaging. Responding to an incident consumes valuable time and resources, pulling your internal IT team away from strategic initiatives and forcing them into a reactive, firefighting mode. A failure to properly secure medical devices creates a cycle of vulnerability that can ultimately harm your organization's good name and operational stability, underscoring the need for proactive managed IT services.
The FDA's Guidelines for Medical Device Security
The FDA provides guidance to help manufacturers design products to be cyber secure, and has recently released a draft guiding a device’s cybersecurity throughout its life cycle. This draft details how the FDA will apply existing regulatory requirements.
The draft guidance establishes six principles of medical device security:
- Cybersecurity is an integral part of device safety
- Security by design
- Transparency
- Security risk management
- Security architecture
- Testing/objective evidence
This guidance strongly recommends manufacturers minimize the cybersecurity risks associated with the design, safety and use of the medical devices by carefully following the six principles outlined.
Cybersecurity as a Shared Responsibility
While manufacturers are on the hook for building secure devices, they aren't the only ones responsible for protecting them. Securing the medical device ecosystem is a team sport, requiring active participation from regulatory bodies, the manufacturers themselves, and the healthcare organizations that deploy the technology. The FDA has been clear that protecting medical devices is a shared job between all stakeholders, including hospitals and doctors. For IT leaders in healthcare, this means understanding your specific role and responsibilities within this framework. It’s not enough to assume a device is secure out of the box; your organization’s network architecture, user training protocols, and continuous monitoring are all critical layers in a robust defense-in-depth strategy.
The Role of the FDA and Device Manufacturers
The FDA sets the baseline by providing guidance to manufacturers on how to design, build, and maintain secure products. Their focus is on encouraging a "security by design" approach, where cybersecurity is a core component from the very beginning of a product's lifecycle, not an afterthought. Manufacturers are expected to conduct risk assessments, implement security controls, and create a plan for identifying and mitigating new vulnerabilities after a device is on the market. This includes transparently communicating any discovered weaknesses to users. This regulatory push ensures that the devices entering your environment have a foundational level of security, but it's just the starting point for your organization's overall cybersecurity posture.
The Healthcare Provider's Role in Patient Security
Once a device is connected to your network, its security becomes a shared responsibility, with a significant portion falling on your team. Many connected devices, especially older ones, weren't built with modern security standards in mind, creating immediate risks to sensitive patient data and operational stability. As a healthcare provider, your role involves implementing a comprehensive security strategy that includes network segmentation, strict access control, and continuous monitoring. Regularly training medical staff on security best practices is also essential to prevent human error from becoming a major vulnerability. Partnering with a security expert can help you manage these complex tasks, from vulnerability assessments to implementing a robust Managed Detection and Response (MDR) solution to keep a close watch on device behavior and network traffic.
How an MSSP Improves Connected Medical Device Security
Achieve Full Transparency
An MSSP can help to guarantee the integrity of medical device networks by providing real-time visibility into device data, creating a secure perimeter and responding quickly to threats. This can prevent disruptions to patient care and ensure that patients’ data is protected.
MSSPs can also provide cybersecurity training to healthcare professionals who are on-the-ground and responsible for patient care. By improving the overall security posture of medical devices, they can safeguard patients as well as the reputations of providers.
Utilize a Software Bill of Materials (SBOM)
Think of a Software Bill of Materials (SBOM) as an ingredients list for your medical devices. It details every software component and library, including those from third-party vendors. This transparency is crucial because, as research from EY points out, many devices weren't built with security as a top priority, leaving them exposed. A security partner uses an SBOM to shift your organization from a reactive to a proactive security posture. By continuously monitoring every component on that list for new vulnerabilities, they can instantly identify which devices are at risk when a threat emerges. This transforms a simple inventory into an active defense mechanism, giving you the visibility needed to effectively manage your device cybersecurity.
Get Proactive with Risk Management
Risk management services protect their clients by conducting a thorough evaluation of the medical device’s cybersecurity vulnerabilities and threats. They then design and implement a security program that ensures the device is protected from hacking, tampering and loss or theft.
An MSSP can help you find and fix vulnerabilities in your systems, applications, networks and devices before an attacker can get access to them.
Implement Penetration and Application Security Testing
A proactive approach means finding security gaps before an attacker does. This involves rigorous testing that simulates real-world cyber-attacks. Penetration testing, for example, actively tries to exploit vulnerabilities in your connected devices and the networks they rely on. Similarly, application security testing examines the device's software and code for weaknesses that could be compromised. By conducting these controlled attacks, a cybersecurity partner can uncover hidden weak spots in the device itself, its communication protocols, or even the cloud infrastructure it connects to. This process provides a clear, actionable roadmap for remediation, allowing you to fix critical vulnerabilities before they can impact patient safety or data integrity.
Establish Continuous Monitoring and Threat Detection
Securing medical devices isn't a one-time project; it requires constant vigilance. The threat landscape evolves daily, and new vulnerabilities can emerge long after a device is deployed. This is where continuous monitoring becomes essential. By establishing 24/7/365 oversight of your device ecosystem, you can detect suspicious activity and potential threats in real time. A partner offering Managed Detection and Response (MDR) services can provide this constant watch, using advanced tools and expert analysis to identify anomalies that might signal an attack. This allows for a swift response to contain threats, minimizing potential damage and ensuring your internal IT team isn't overwhelmed by the noise of constant alerts.
Pinpoint Threats with In-Depth Risk Analysis
A risk analysis is an examination of the risks a network faces and the weaknesses in the network. An MSSP can conduct a risk analysis to determine a device’s vulnerabilities and provide recommendations for improvement. If a device has a high risk of being compromised, the MSSP can help you replace the device with a more secure version.
For example, a medical device manufacturer may allow a software developer to test the software for security vulnerabilities on their product before it is released to the public. If vulnerabilities are found, then the software developer may begin working with the device manufacturer to address those issues in order to prevent unauthorized access.
Conduct Regular Device Audits
Device auditing is the process of examining a device’s software, firmware, and operational procedures. An MSSP can audit a device’s software and firmware to detect weaknesses. They can also examine the device’s operational procedures to ensure it is being used properly.
Manage the Entire Device Lifecycle
Effective medical device security isn’t a one-time fix; it’s a commitment that spans the entire lifecycle of the device. The FDA emphasizes that cybersecurity is an integral part of device safety, meaning it must be built in from the very beginning, not bolted on as an afterthought. This "security by design" approach ensures that potential vulnerabilities are addressed during development, manufacturing, and deployment. An MSSP can help enforce this by providing continuous vulnerability scanning and threat monitoring from the moment a device is connected to your network, ensuring it remains secure through patches, updates, and eventual decommissioning.
Improve Accountability and Staff Training
Even the most secure device can be compromised by human error. Cybersecurity is a shared responsibility that extends from the manufacturer to the healthcare provider and even the patient. To strengthen this human firewall, it's essential to regularly train medical staff and administrators on current cybersecurity best practices. A knowledgeable team is your first line of defense against phishing attempts and other social engineering tactics. An experienced MSSP can provide tailored cybersecurity training for your healthcare professionals, ensuring they have the skills to recognize and report threats, which is a critical component of our comprehensive managed IT services.
Stay on Top of Regulatory Compliance
Healthcare organizations need to take steps towards regulatory compliance to ensure that the devices they produce continue to be safe and effective.
It’s critical medical device manufacturers and healthcare professionals take steps to prevent cyber-attacks from happening, and regulatory compliance is an important part of this process. It helps ensure that medical device companies comply with all applicable laws and regulations that protect both patients and the overall health care system.

Frequently Asked Questions
My IT team is highly capable. Why would we need an outside partner specifically for medical device security? This isn't about questioning your team's skill; it's about the unique scale and nature of the challenge. Securing medical devices requires a specialized focus that goes beyond traditional IT. An expert partner brings dedicated tools and experience to continuously monitor thousands of devices, analyze specific threats to healthcare, and manage vulnerabilities in legacy equipment that can't be patched. This allows your internal team to focus on their core strategic projects instead of being overwhelmed by the sheer volume of device-specific security alerts.
Many of our critical devices are older and can't be updated. How can they possibly be secured? This is a common and serious concern. While you can't patch the software on these legacy devices, you can build a strong security perimeter around them. A security partner can help by implementing network segmentation, which isolates these vulnerable devices from the rest of your network. This prevents an attacker who compromises an old device from moving laterally to access sensitive data. Continuous monitoring is also key, as it allows for the detection of any unusual behavior from these devices, signaling a potential threat in real time.
What's the first practical step we should take to get a handle on our medical device security? The best starting point is to gain full visibility of what's on your network. You can't protect what you don't know you have. A comprehensive inventory, often facilitated by a security partner, helps identify every connected device. This process should include creating a Software Bill of Materials (SBOM) for each device, which lists all its software components. This "ingredients list" is the foundation for a proactive security strategy, as it allows you to quickly identify which devices are affected when a new vulnerability is discovered.
The FDA and manufacturers have security responsibilities. What is our specific role as a healthcare provider? While manufacturers are responsible for building secure devices, your organization is responsible for how they are used and protected within your own environment. Once a device connects to your network, its security becomes a shared task. Your role includes ensuring the network itself is secure, controlling who has access to the devices, and providing regular security training for your staff. Think of it this way: the manufacturer provides a secure lock for the door, but you are responsible for making sure the door is locked and monitoring who comes and goes.
How does a Managed Security Service Provider (MSSP) do more than just send alerts? A true security partner does far more than just monitor for threats; they provide a complete service that includes proactive measures and rapid response. For example, they conduct penetration testing to find weaknesses before attackers do and manage the entire device lifecycle from deployment to decommissioning. When a threat is detected through a service like Managed Detection and Response (MDR), their team of experts analyzes the threat, contains it, and provides clear guidance for remediation, effectively acting as an extension of your own team.
Key Takeaways
- Treat Device Security as Patient Safety: A compromised medical device isn't just a data breach; it's a direct threat to patient care. Securing these endpoints, especially outdated legacy systems that can't be patched, is a critical clinical responsibility.
- Your Responsibility Starts at the Network Jack: While manufacturers and the FDA have roles, your organization is accountable for protecting devices once they're connected. This requires active defenses like network segmentation, continuous monitoring, and consistent staff training.
- Augment Your Team with Expert Security Management: The sheer volume and complexity of medical devices demand specialized, constant attention. An MSSP acts as a force multiplier for your team, providing proactive risk analysis, continuous monitoring, and lifecycle management to secure your environment.
