Challenges and Risks in Medical Device Vulnerability Scanning
Common Challenges When Scanning Connected Medical Devices
Scanning medical devices isn’t as straightforward as dealing with traditional IT systems. One major hurdle is the prevalence of legacy systems. Many medical devices have lifecycles spanning decades, often running outdated software that no longer gets security updates [3][4]. In fact, about 14% of connected medical devices operate on unsupported operating systems, leaving them vulnerable to known exploits [7].
Another challenge is the lack of an accurate device inventory. Without a clear understanding of what devices are in use, it’s nearly impossible to make informed, risk-based decisions [3]. On top of that, healthcare delivery organizations often face resource constraints - they may lack the specialized staff or budget necessary to implement robust vulnerability management workflows [3].
Adding to the complexity are evolving regulations and the downtime required for testing and applying updates. Some patches might even trigger the need for regulatory re-certification, further delaying implementation [3][5]. Many devices also come with insecure default settings, such as hardcoded passwords, open ports, and enabled remote access, which cannot always be easily altered [6]. Together, these factors create a challenging environment, where improper scanning can lead to significant risks.
What Can Go Wrong with Improper Scanning
The stakes are high when scanning isn’t done carefully. Legacy devices are particularly fragile; their outdated network stacks can crash or reboot under the strain of heavy scan traffic [3]. Such disruptions can interfere with clinical workflows, potentially leading to misdiagnosis or delayed treatments - both of which can directly affect patient safety and outcomes [7].
Consider this: 74% of hospitals using legacy systems reported at least one cyber incident in the past year, and 53% of networked medical devices have at least one critical vulnerability [7]. The most frequently targeted devices include imaging systems (41%), patient monitoring devices (40%), and laboratory equipment (34%) [5][6]. When scans disrupt these systems, the consequences can be immediate and, in some cases, life-threatening.
The FDA has warned that, "Left unpatched or otherwise mitigated, these vulnerabilities could allow unauthorized users to access, control, and issue commands to compromised devices, potentially leading to patient harm" [8]. Alarmingly, only 43% of healthcare security professionals upgraded legacy systems after a ransomware attack, showing that even after experiencing the fallout of poor vulnerability management, many organizations continue to face the same challenges [7].

Beyond the Surface: Understanding Different Types of Vulnerability Scans
Passive vs. Active Vulnerability Scanning Methods
Passive vs Active Vulnerability Scanning Methods for Medical Devices
How Passive and Active Scanning Differ
When it comes to scanning medical devices, healthcare organizations rely on two main approaches: passive scanning and active scanning. Knowing how these methods differ is key to safeguarding both network security and patient care.
Active scanning involves directly interacting with devices by sending probes or queries to detect open ports, services, and potential vulnerabilities [9]. While this approach provides detailed insights into device configurations and hidden risks, it comes with notable challenges. As CyCognito highlights:
Active reconnaissance can also risk disrupting system operations, leading to downtime or other negative consequences [9].
For medical devices that need to function continuously - like ventilators or infusion pumps - such disruptions could pose serious risks to patient safety.
On the other hand, passive scanning works by observing network traffic at the packet level (IPv4, IPv6) without directly engaging with the devices [9][10]. CyCognito describes it as:
Passive reconnaissance focuses on gathering information about a target system without direct interaction [9].
This method is safer for sensitive equipment, as it avoids any risk of interfering with device operations. However, it is less detailed, relying solely on the data available from network traffic.
A practical approach combines both methods. Passive monitoring can help build a complete inventory of devices without causing any disruptions. Active scanning, meanwhile, can be reserved for scheduled maintenance windows, where deeper analysis can be performed with minimal clinical impact. This strategy ensures ongoing visibility while limiting risks during active assessments [9].
Comparing Scanning Methods
| Aspect | Passive Scanning | Active Scanning |
|---|---|---|
| Intrusiveness | Low (observes traffic) | High (sends requests) |
| Comprehensiveness | Less detailed | More detailed |
| Use Case in Healthcare | Initial discovery and continuous monitoring | Targeted assessments during maintenance windows |
| Disruption Risk | Minimal | High (potential for downtime) |
These distinctions guide best practices for secure and effective vulnerability scanning in healthcare settings. By balancing the strengths of both methods, organizations can maintain safety and compliance while minimizing operational risks.
Best Practices for Safe and Compliant Vulnerability Scanning
Preparing for Scans to Meet Compliance Requirements
Before conducting vulnerability scans, it's crucial to manually verify network boundaries in collaboration with biomedical engineering teams. Start with light discovery scans to create a risk-free asset inventory [11]. Joe Agnew from Rapid7 highlights that many teams face challenges in identifying all networked assets [11]. This step is especially important in clinical networks, which can host as many as 25,000 devices [12]. Building an accurate inventory upfront helps address issues like legacy systems and undocumented devices.
Light discovery scans work by identifying and fingerprinting assets using basic details such as open ports, services, and operating system signatures [11]. For a deeper dive, perform aggressive testing in a pre-production environment. This method helps identify potential device failures under scanning conditions before deploying scans in live clinical settings [11].
To minimize disruptions, align scans with existing biomedical maintenance schedules. Conduct scans when devices are already offline for routine checks [11][12]. This approach ensures compliance and avoids interrupting critical patient care. Once these steps are in place, attention shifts to ensuring patient safety during the actual scanning process.
Protecting Patient Safety During Scans
Even with compliance measures in place, safeguarding patient safety remains the top priority during active scanning. Many medical devices are highly sensitive, and scanning them while they are in use could compromise their functionality. The golden rule is straightforward: never scan devices actively treating patients [11][12]. Joe Agnew underscores this principle:
"Information security should never harm a patient" [11].
The fragile TCP/IP implementations in many medical devices make them vulnerable to failures during standard network scans [11]. Such failures could lead to device downtime or even adverse outcomes for patients [11].
To manage risks, prioritize devices using a risk-based framework. Skip Sorrels, Director of Cybersecurity at Ascension, emphasizes this approach:
"If this device is compromised will someone die? If the answer is 'Yes,' it is imperative to put this device at the top of vulnerability remediation" [12].
Rather than relying solely on CVSS scores, consider using tools like the Known Exploited Vulnerabilities (KEV) catalog and the Exploit Prediction Scoring System (EPSS). These resources help focus remediation efforts on vulnerabilities that pose real-world threats [3]. For example, in 2017, nearly 500,000 pacemakers were recalled due to exploitable vulnerabilities, illustrating the critical need for targeted security measures [13].
