Medical Device Cybersecurity Statistics and Impact of Automated Scanning
How Automated Scanning Works for Medical Devices
What is Automated Vulnerability Scanning
Automated vulnerability scanning involves using specialized software to systematically inspect networks and medical devices for security weaknesses, often referred to as CVEs (Common Vulnerabilities and Exposures). This process identifies essential details about each device, such as open ports, running services, and operating system information, creating a digital "fingerprint" for every asset. This fingerprinting is especially critical for medical devices, as many of them do not have dedicated CVE entries in standard vulnerability databases [2].
Once the system gathers the device's details, the software compares them to vulnerability databases, flagging any potential risks. For healthcare organizations managing thousands of interconnected devices, automation is indispensable. The sheer volume of devices and the rapid emergence of new vulnerabilities make manual tracking nearly impossible in 2024 [4].
With this groundwork in place, let's explore how these scans are conducted.
Types of Scanning Techniques
Different scanning methods address various stages of the security lifecycle. Static Application Security Testing (SAST) inspects code or firmware without running it, while Dynamic Application Security Testing (DAST) evaluates live, operational systems [4].
Healthcare organizations often choose between two primary scanning approaches:
- Authenticated Scans: These use login credentials to simulate what a compromised account might access within the system.
- Unauthenticated Scans: These mimic an external attacker’s perspective, focusing on the network's perimeter [3].
For medical devices, light discovery scans have become the norm. These scans are designed to probe devices without overwhelming their often fragile TCP/IP implementations [2]. Together, these methods provide the foundation for consistent, automated monitoring of medical device networks.
Automated vs. Manual Scanning
Understanding the differences between automated and manual scanning highlights the efficiency of automation. The increasing number of CVEs has made manual assessments unfeasible [4]. Automated scanning can run continuous or recurring checks across entire networks at a fraction of the cost of manual penetration testing, which requires highly skilled professionals and is typically limited to specific, targeted assessments [3].
"Vulnerability scans are automated, high-level scans of assets. They find flaws and report them to the security team. Penetration testing, or pen testing, is a manual process." - IBM [3]
While manual testing remains valuable for deep-dive validation, it is typically conducted periodically. The real advantage of automation lies in its scalability. However, even with automation, security teams still spend 30%-40% of their time managing false positives rather than addressing genuine vulnerabilities [4].

Implementing Automated Scanning in Medical Device Workflows
Scanning During the Development Lifecycle
In the pre-production phase, rigorous testing is crucial. Before integrating devices into a network, it's important to create a detailed device fingerprint by identifying open ports, services, and operating systems. This fingerprinting process helps uniquely identify and manage devices during pre-production testing [2].
"Pre-production is the time to try to break things. Scan, attack, throw the kitchen sink at it. It's better to learn a device falls over from a particular type of scan during pre-production, rather than when it's deployed to the network."
– Joe Agnew, Rapid7
Security testing should also be integrated into DevOps pipelines to streamline the process. For example, a Jenkins server can trigger automated security tests alongside functional tests. This approach helps uncover whether a device’s TCP/IP stack or hardware specifications might fail under scanning conditions.
Once pre-production testing is thoroughly completed, the focus shifts to ensuring safe and effective scanning practices in production environments.
Safe Scanning in Production Environments
Insights gained during pre-production are invaluable for scanning in production, but the approach must be handled with care. Under no circumstances should security teams scan devices actively connected to patients. The potential risk to clinical operations and patient safety far outweighs any security gains [2]. Instead, coordinate with biomedical engineering teams to schedule scans during maintenance windows, ensuring devices in use remain unaffected.
For active networks, low-impact scans can identify assets and detect unauthorized devices while minimizing stress on fragile systems. Security teams should also verify network segmentation by physically observing device deployments and reviewing logs and firewall configurations. Relying on assumptions about segmentation can lead to critical gaps.
"Information security should never harm a patient."
– Joe Agnew, Rapid7
Continuous Monitoring and Post-Deployment Scanning
Medical devices often have lifecycles spanning decades, frequently running outdated software that no longer receives security updates [1]. This makes continuous monitoring essential. By extending the fingerprinting process established earlier, ongoing monitoring helps identify and manage legacy vulnerabilities throughout the device’s lifecycle. In healthcare settings, vulnerability scanners are primarily used to track and fingerprint assets, as many medical device vulnerabilities don’t appear in standard CVE databases [2].
When it comes to prioritizing remediation, relying on tools like the Known Exploited Vulnerabilities (KEV) catalog and the Exploit Prediction Scoring System (EPSS) provides better insight into actively exploited vulnerabilities compared to CVSS scores alone [1]. Keeping an up-to-date inventory of device details - such as operating system versions, software versions, and physical locations - ensures efficient tracking and remediation efforts [1].
Meeting Regulatory Standards with Automated Scanning
Medical Device Cybersecurity Regulations
Healthcare organizations face strict rules when it comes to securing medical devices. Under FDA Section 524B of the FD&C Act, manufacturers are required to monitor and address vulnerabilities in devices that include software, connect to the internet, or have features that could be exploited by cyber threats. Similarly, ISO 14971:2019 emphasizes managing risks throughout a device's lifecycle, requiring the identification of cybersecurity hazards and thorough documentation.
For data privacy, regulations like HIPAA and ISO 27799 mandate safeguards such as encryption (both for stored and transmitted data) and access controls to protect sensitive patient health information. Meanwhile, the EU MDR 2017/745 insists on secure design principles and rigorous post-market monitoring. Automated scanning tools play a key role in meeting these expectations by continuously detecting vulnerabilities and creating the necessary documentation regulators demand. These tools simplify compliance by ensuring precise records and smoother workflows.
Here’s why this matters: surveys reveal that 53% to 60% of connected medical devices have critical vulnerabilities [5]. Even more concerning, 73% of networked IV infusion pumps have at least one security flaw [5]. In 2022 alone, medical device vulnerabilities increased by 59% compared to the previous year [5].
"Cybersecurity is directly a patient-safety issue. Unlike typical IT, attacks on medical devices can cause physical harm or death." – Adrien Laurent, IntuitionLabs [5]
Documenting Scans for Regulatory Audits
Given these regulatory demands, maintaining detailed audit trails is essential. Regulators require proof of every scan conducted. Automated scanning tools should produce comprehensive records, including details on what was scanned, when it was scanned, the vulnerabilities identified, and the steps taken to address them. These records must align with your Quality Management System (QMS) to meet FDA and ISO 13485:2016 requirements.
For FDA submissions, it’s crucial to document scan results and remediation plans thoroughly to avoid delays caused by technical screening holds. Organizations working with AI-enabled devices face additional challenges, as scanning must also account for input validation and monitoring for adversarial attacks. This is especially important given that, as of 2025, the FDA has authorized over 1,000 AI-enabled medical devices for marketing [5].
