Why this matters

The FDA's Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions (Feb 3, 2026 final guidance) made cybersecurity documentation a gating criterion for clearance under Section 524B of the FD&C Act. Reviewers now apply this guidance to medical device hazard analysis and critcal control points the same way they apply software lifecycle expectations from IEC 62304 and security risk-management expectations from AAMI TIR57 and ANSI/AAMI SW96:2023.

Gaps in this area are the single most common driver of first-cycle cybersecurity Additional Information (AI) requests. The FDA's FY2024 CDRH performance reports show cybersecurity is among the top deficiency categories cited in 510(k) and PMA AI letters, behind only software documentation and clinical evidence. Treating it as a checklist exercise rather than a design-controlled engineering artifact is what creates the gap.

Understanding Medical Device Hazard Analysis

Hazard analysis identifies and reduces potential risks tied to medical devices. It is a systematic approach that involves evaluating every stage of a device’s lifecycle, from design to disposal.

Definition and Purpose of Hazard Analysis

Hazard analysis identifies hazards a medical device may pose to patients, users, or the environment. The goal is simple: find what can go wrong, then put controls in place to reduce or remove the risk.

Components of Hazard Analysis

Hazard analysis starts with identifying potential hazards tied to a medical device. That means reviewing device design, materials, intended use, and the environment where the device will operate. It also includes assessing the severity of each identified hazard and the likelihood it will occur. That lets teams rank risks and deal with the most serious ones first.

The Role of Hazard Analysis in Medical Device Safety

Hazard analysis supports the safety and effectiveness of medical devices. Manufacturers use it to identify risks early and build devices that meet safety requirements. It also helps healthcare professionals make informed decisions when using medical devices. It guides us away from harm and towards optimal patient care.

Hazard analysis also matters for regulatory compliance. Agencies such as the Food and Drug Administration (FDA) require manufacturers to conduct hazard analysis as part of premarket review. That helps ensure devices entering the market have been evaluated for potential risks.

Hazard analysis is not a one-time task. It continues across the device lifecycle so teams can identify new hazards and respond before they become patient safety issues.

The Concept of Critical Control Points

Critical control points are the places in a device lifecycle where teams can prevent, reduce, or monitor risks found during hazard analysis.

Defining Critical Control Points

Critical control points are specific stages in the development, manufacture, and use of medical devices where control measures can be applied. These measures keep hazards from reaching patients and end users. From design controls to manufacturing practices and post-market surveillance, critical control points help manage risk throughout the device lifecycle.

The Role of Critical Control Points in Risk Management

Risk management depends on putting controls in the right places. Critical control points let manufacturers act before a hazard causes harm. When control measures are applied at the right stages, the chance of patient harm drops.

Identifying Critical Control Points in Medical Devices

Identifying critical control points means reviewing the key processes involved in developing, manufacturing, and using medical devices. The goal is to find the stages that need tighter monitoring and stronger controls.

One example is design controls. During design, engineers review intended use, performance requirements, and possible risks. That is the point where many hazards can be identified and reduced before they carry into production.

Another key control point is manufacturing. This is where the design becomes a real product. Quality controls and inspections are needed to make sure the device matches specifications and meets regulatory requirements. Good manufacturing practices reduce defects and deviations that could create patient risk.

The Interplay Between Hazard Analysis and Critical Control Points

Hazard analysis and critical control points are connected parts of a quality management system. Hazard analysis finds the risks. Critical control points are where those risks are controlled.

How Hazard Analysis Informs Critical Control Points

Hazard analysis gives manufacturers the information needed to place control measures where they matter most. By identifying, assessing, and ranking hazards, teams can focus resources on the control points that have the biggest effect on product safety.

Hazard analysis also includes risk assessment and prioritization. When risks are ranked by severity and likelihood, manufacturers can focus on critical control points with the highest safety impact.

The Synergy Between Hazard Analysis and Critical Control Points

These two processes work together. Hazard analysis identifies risk. Critical control points reduce or contain it. Used together, they help manufacturers meet regulatory requirements and protect patients.

This connection also supports continuous improvement. As new information appears and risks change, manufacturers can update both hazard analysis and critical control points to address new safety concerns and technology changes.

The Regulatory Perspective on Hazard Analysis and Critical Control Points

Regulators expect manufacturers to use hazard analysis and critical control points to support device safety and effectiveness.

Regulatory bodies around the world oversee medical device manufacturing, distribution, and use. They set standards intended to protect patients and healthcare professionals.

FDA Guidelines on Hazard Analysis and Critical Control Points

The United States Food and Drug Administration (FDA) has issued guidance to help manufacturers conduct hazard analysis and implement critical control points.

Under FDA guidance, manufacturers must identify hazards tied to their devices, assess the risks, and establish measures to reduce or eliminate them. Following this guidance improves product safety and reliability and supports regulatory review.

International Standards for Medical Device Safety

Medical device safety is a global issue, and international standards give manufacturers a common framework. These standards set expectations for hazard analysis and critical control point implementation, which helps align safety practices across markets.

Harmonized international standards also make regulatory processes and cross-border market access easier. They show that a manufacturer is following recognized safety and quality expectations.

Challenges and Solutions in Implementing Hazard Analysis and Critical Control Points

Hazard analysis and critical control points are useful, but implementation is not always straightforward. Manufacturers run into process, staffing, and operational issues.

Common Obstacles in Hazard Analysis and Critical Control Points Implementation

Implementation often runs into limited resources, inconsistent processes, and resistance to change. These are common problems, and they slow down risk management work if they are not addressed early.

Global supply chains add more difficulty. Manufacturers may need to coordinate across multiple sites, work through language barriers, and keep practices consistent across teams.

Strategies for Effective Implementation

Manufacturers can improve implementation by investing in training, building a culture of continuous improvement, and using technology where it helps.

It also helps to work with industry peers, stay engaged with regulators, and perform regular audits and reviews. Those steps improve consistency and make the process easier to maintain over time.

The Future of Hazard Analysis and Critical Control Points in the Medical Device Industry

As medical technology changes, hazard analysis and critical control points need to keep pace.

Technological Advancements and Their Impact

Artificial intelligence and the Internet of Things, medical devices are becoming smarter and more interconnected . That creates new ways to improve hazard analysis and critical control points, including real-time monitoring and predictive analytics.

Virtual reality and augmented reality are also changing how healthcare professionals interact with devices and data. These tools can support hazard analysis by simulating scenarios in controlled environments.

The Role of Hazard Analysis and Critical Control Points in Future Medical Device Development

Hazard analysis and critical control points will remain central to future medical device development. New technologies do not reduce the need for risk management. They increase it.

Personalized medicine and wearable medical devices create new risk profiles. That means hazard analysis must adapt to individual patient contexts and changing conditions while maintaining device safety and effectiveness.

Conclusion

Hazard analysis and critical control points help protect patients, users, and the environment from device-related risks. They support safer medical devices and stronger risk management across the product lifecycle.

This work often takes hours or days to uncover a chain of flaws that would allow those controls to be bypassed.

We also assess the physical aspects of the device. That includes checking for alternate ports such as JTAG, UART, other unprotected ports, additional USB ports, and accessible hard drives.

The assessment also covers forensics and post-exploitation movement, including detonating payloads, pivoting, and adjusting operating systems to simulate real-world scenarios that could affect patient care. In addition, we reverse engineer proprietary binaries and programs, searching for sensitive keys to determine whether encryption uses statically set or dynamically created keys.

This penetration test gives you a full view of your medical device’s security weaknesses. The findings support practical recommendations for patching and hardening the device, which improves patient safety and reduces organizational risk.

What is AAMI TIR57?

AAMI TIR57 is a technical information report focused on the principles for medical device security-risk management. It's a guideline from the Association for the Advancement of Medical Instrumentation (AAMI), an organization well-known for its work in medical devices.

Overview

AAMI TIR57, titled "Principles for medical device security-Risk management," offers a structured approach to managing cybersecurity risks in medical devices. This is particularly important because medical devices, like any other connected technology, can be vulnerable to cyber threats. This report provides guidance on implementing security measures throughout a device's lifecycle, from design and development to decommissioning.

The "Why"

TIR57 matters because it focuses on patient safety and data security. As medical devices become more interconnected and software-dependent, they become more exposed to cyber threats. Those threats can affect device functionality and lead to patient harm. TIR57 helps manufacturers and healthcare providers reduce these risks by establishing sound security practices.

Examples and Case Studies

For example, a hospital may use networked medical devices like heart rate monitors or insulin pumps. These devices are critical for patient care. If weak security allows them to be hacked, the result could be anything from a data breach to a life-threatening event. Using the principles in AAMI TIR57, such as thorough risk assessments and cybersecurity review during design, helps prevent that.

For Blue Goat Cyber, understanding and applying AAMI TIR57 supports services that align with recognized standards. That includes risk assessments, guidance on secure device design, and ongoing security support.

Connecting the Dots

AAMI TIR57 is more than guidance. It is a framework for helping secure medical devices and support patient safety. Using its principles in your services positions Blue Goat Cyber as a provider that understands both cybersecurity and the specific demands of medical devices.

Understanding and applying AAMI TIR57 can also help when talking to healthcare cybersecurity decision-makers. They want experts who understand the technical side of cybersecurity and the realities of medical devices.

What is a Cybersecurity Bill of Materials (CBOM)?

A Cybersecurity Bill of Materials (CBOM) is an essential requirement enforced by the FDA from March 29, 2023, onwards for medical devices. It mandates medical device manufacturers to provide a comprehensive and accurate list of software and hardware components used in their devices, including any third-party software and open source components. This list, known as the CBOM, serves as a self-attestation by manufacturers, indicating the accuracy and completeness of the components used in their medical devices. One critical aspect of the CBOM is the inclusion of a Software Bill of Materials (SBOM), which ensures complete transparency regarding software components used in medical devices. Given the crucial nature of medical devices and the potential risks associated with cybersecurity, having a comprehensive and accurate SBOM is particularly vital in maintaining the security and integrity of these devices.

How can Blue Goat help in generating accurate SBOMs?

The terms "Cybersecurity Bill of Materials" (CBOM) and "Software Bill of Materials" (SBOM) are related concepts in the realm of cybersecurity and software management, often used within the context of improving transparency and security of software products and systems, including medical devices. The primary distinction between the two lies in their scope and specific focus:

See also: NeuroTech Cybersecurity Risks: Neurostimulators, EEG, & BCI, The Overlooked Threat in MedTech Innovation, and Mastering Cybersecurity in MedTech.

1. Software Bill of Materials (SBOM): An SBOM is a detailed list that provides an inventory of all components, libraries, and modules that make up a piece of software, including both open-source and proprietary elements. The primary purpose of an SBOM is to give users (which can include end-users, developers, and security professionals) a clear understanding of what software is running in their environment. This transparency is crucial for vulnerability management, license management, and security analysis, enabling users to identify potential security risks, comply with licensing requirements, and perform effective patch management.

2. Cybersecurity Bill of Materials (CBOM): A CBOM extends the concept of an SBOM by including not just software components but also detailing hardware components, network dependencies, and any other elements critical to understanding the cybersecurity posture of a device or system. The CBOM is particularly relevant in contexts where the security of the entire ecosystem, including physical components and network interactions, is critical. For example, understanding the full spectrum of components and dependencies in medical devices or industrial control systems is essential for assessing vulnerabilities, potential attack vectors, and overall system security.

In essence, while an SBOM is specifically focused on software components, a CBOM provides a broader view that encompasses all elements relevant to cybersecurity. Both are tools aimed at enhancing the security and manageability of software and systems, but they do so from slightly different angles. The adoption of SBOMs and CBOMs is encouraged by various cybersecurity frameworks and standards to promote transparency and facilitate better risk management practices.

What is the significance of SBOMs and SPDX in the present and future?

March 29, 2023, marked a significant milestone as the FDA began enforcing cybersecurity requirements for medical devices, urging manufacturers to comply with a Cybersecurity Bill of Materials (CBOM). A crucial element of the CBOM is the inclusion of a Software Bill of Materials (SBOM), which outlines the comprehensive list of software and hardware components utilized within medical devices. This encompasses not only internally developed software but also third-party software and open-source components.

The significance of SBOMs lies in their ability to enhance transparency and accountability in the supply chain of medical devices. By mandating medical device manufacturers to self-attest to the accuracy of their SBOMs, regulators can obtain a holistic view of the components employed in the production of these devices. This promotes better assessment and management of potential security vulnerabilities.

One of the recognized standards for SBOMs is the Software Package Data Exchange (SPDX) format. SPDX provides a consistent and standardized way to document and share SBOMs, enabling efficient communication between various stakeholders, including manufacturers, regulators, healthcare providers, and consumers. This universal language supports interoperability and simplifies the evaluation of SBOMs by allowing for easy comparison and analysis.

The significance of SBOMs and SPDX in the present and future lies in their ability to strengthen cybersecurity practices and improve transparency across industries, not just within the medical field. As highlighted by the National Telecommunications and Information Administration (NTIA), the implementation of SBOMs should extend beyond medical devices, becoming a common practice in other sectors as well. This indicates a growing recognition of the importance of understanding and managing the software components in all connected systems.

With the regulatory enforcement of SBOMs, companies across industries are actively working towards creating compliant SBOMs, with some seeking assistance from third-party providers who specialize in generating accurate and complete SBOMs. These providers, like Synopsys, offer sophisticated tools and solutions that can precisely identify software components used, including third-party and commercial components. They can also ensure that the generated SBOMs align with the specific requirements set forth by regulatory bodies, such as the FDA.

What are the additional elements required by the FDA for an SBOM?

The FDA has established additional requirements for a Software Bill of Materials (SBOM) for medical devices. In addition to the minimum elements defined by the National Telecommunications and Information Administration (NTIA), the FDA mandates including specific information. These additional elements encompass the support level, support end date, and known security vulnerabilities of the software components used in the medical devices.

While open source projects may not have designated support levels or support end dates, these additional elements largely apply to third-party or commercial components integrated within the medical device application. It is crucial to include complete and accurate SBOMs for medical devices, as they enable transparency and focus on cybersecurity.

What is some background on medical device vulnerabilities?

Over the past few years, the Internet of Things (IoT), coupled with the widespread nature of Information Technology, has resulted in an expanding attack surface where rapid solution development and enhanced functionality routinely prevail over security. For example, attackers once disrupted most U.S. internet activity using 61 default IoT usernames and passwords. Consumers failed to change them before activating their devices, effectively turning our gadgets into culprits responsible for one of the largest Distributed Denial of Service (DDoS) in the world’s history.

The healthcare industry is rapidly adopting IoT devices, often called the Internet of Medical Things (IoMT), to improve patient safety and healthcare workers' treatment delivery. From medication administration to remote sensor monitoring, embedded medical devices are improving quality of care and increasing interaction with providers. But the lack of security in product design phases remains a major concern and will likely lead to malicious activity with serious consequences.

The consequences became clear in 2017 as researchers were able to acquire equipment (from $15 - $3,000) and intercept the radio frequencies from cardiac devices. With this capability, they could reprogram the devices to modify the patient’s heartbeat and drain the internal battery. As a result, the FDA recalled almost 500,000 pacemakers and enforced in-person firmware updates. Researchers have also demonstrated similar capabilities on infusion pumps and MRI systems.

Non-networked medical devices may be operating at a higher level of risk. Ease of access and the availability of RFID cloners contribute to a relatively weak physical security posture. In 2018, researchers demonstrated the capability to emulate and alter a patient’s vital signs in real time using an electrocardiogram simulator they found on eBay for $100.

In late 2018, the Department of Health and Human Services Office of the Inspector General (IG) critiqued FDA procedures in assessing post-market cybersecurity risk to medical devices. To support the FDA's core mission “to ensure there is a reasonable assurance that medical devices legally marketed in the United States are safe and effective for their intended uses,” they outlined ongoing efforts to improve medical device security.

According to the FDA, “Healthcare Delivery Organizations (HDOs) are responsible for implementing devices on their networks and may need to patch or change devices and/or supporting infrastructure to reduce security risks. Recognizing that changes require a risk assessment, the FDA recommends working closely with medical device manufacturers to communicate necessary changes.”

Blue Goat can help HDOs transfer that risk by evaluating the cybersecurity posture on your wired or wireless medical devices.

What are some reasons for the lack of security in many medical devices?

The lack of security in many medical devices can be attributed to several key factors. One significant factor is the increased scrutiny over the vulnerabilities of these devices, which ultimately forced regulatory bodies like the FDA to reassess their cybersecurity requirements. A report by the FBI revealed that a staggering 53% of digital medical devices and internet-connected products had critical vulnerabilities, exposing patients and medical providers to various security risks. These vulnerabilities were often found in unpatched and outdated devices, which served as the weak link in the cybersecurity chain. Moreover, research suggests that 88% of healthcare cyberattacks involved an IoMT (internet of medical things) device, further underscoring the urgent need for stronger security measures.

Inadequate security controls in medical devices have long been a serious issue. Many of these devices have been designed with a primary focus on their medical functions, with security measures being added as an afterthought, if at all. These "bolted on" security controls have proven to be less than adequate, leaving vulnerabilities that malicious actors can exploit. Additionally, the lack of mandatory requirements and accountability in the past has contributed to the lax approach towards security in the industry. However, recent changes have brought about a much-needed shift in mindset. The introduction of new regulations and the potential for costly fines for non-compliance have made it clear that the days of overlooking security are over.

What is the purpose of the new cybersecurity regulations implemented by the FDA?

The FDA's new cybersecurity regulations have been put in place to ensure the security of medical devices. Section 524B (c) of these regulations defines a device that falls within the scope of these requirements. According to this section, a device is considered to be within the regulations if it includes software that is validated, installed, or authorized by the sponsor of the device or within it. Additionally, the device must be able to connect to the internet and possess technological characteristics that have been validated, installed, or authorized by the sponsor. This definition highlights the potential vulnerability of these devices to cyber threats. The purpose of these regulations is to address these vulnerabilities and establish a higher level of accountability and responsibility among medical device manufacturers. By mandating compliance and introducing potentially costly fines for non-compliance, the FDA aims to ensure that these regulations have a tangible and meaningful impact on the security of medical devices. The focus on accountability signifies a shift from the previous voluntary compliance approach, making it clear that laxity in cybersecurity measures is no longer acceptable in the medical device industry.

What is the FDA's new requirement for connected medical devices?

The FDA has introduced a new requirement for connected medical devices, which went into effect on March 29, 2023. This requirement focuses on cybersecurity and aims to enhance the safety and security of these devices. One component of this requirement is the implementation of a Cybersecurity Bill of Materials (CBOM).

Under the CBOM, manufacturers of medical devices will need to attest to the accuracy of a comprehensive list of software and hardware components utilized in their devices. This list should include the components developed by the manufacturer and any third-party software and open-source components incorporated into the device.

Specifically, the FDA emphasizes the significance of a Software Bill of Materials (SBOM) within the CBOM framework. An SBOM is essential for connected medical devices as it provides a complete and accurate inventory of all software components used. It allows for better tracking of potential vulnerabilities and aids in efficient response and mitigation of any possible cybersecurity incidents.

By enforcing this new requirement, the FDA aims to ensure that manufacturers prioritize cybersecurity in developing and maintaining connected medical devices. Ultimately, this initiative seeks to enhance these devices' overall safety and security, benefiting healthcare professionals and patients alike.

How can cybersecurity vulnerabilities in medical devices lead to patient data breaches?

Why don't traditional cyber defense tools work with medical devices?

Traditional cyber defense tools are not compatible with network connected medical devices for several reasons. First, these devices often lack the infrastructure needed to support security tools. Unlike standard computers or mobile devices, medical devices have limited processing power, memory, and storage. That makes it impractical, and sometimes impossible, to run resource-intensive security software on them.

Also, applying software modifications to these devices could be viewed as tampering and may affect compliance with regulations, specifically those set by the Food and Drug Administration (FDA). The FDA has emphasized the importance of manufacturers implementing adequate security measures, but restrictions on modifying devices make post-production security improvements harder.

Traditional security tools are also designed for more conventional systems and networks. They may not be built to address the specific vulnerabilities and technical details of medical devices. As a result, they may fail to identify or mitigate threats that specifically target these devices.

Because medical devices are critical and cybersecurity failures can directly affect patient safety, manufacturers need to build proper security tools and controls into the design and production of the device from the start. That also helps with FDA compliance.

Who is responsible for maintaining security within medical devices?

Maintaining security within medical devices is the responsibility of manufacturers. The FDA emphasizes that manufacturers are required to stay diligent in identifying and addressing risks and hazards associated with their devices, including those related to cybersecurity. However, it is noted that not all manufacturers take this responsibility seriously.

What types of medical devices are at the highest risk of being hacked?

The types of medical devices that are most vulnerable to hacking are stationary devices. While it is unsettling to contemplate the possibility of internally embedded medical devices being hacked and tampered with, it is important to note that the primary motivation for hackers is financial gain rather than terrorism. These cybercriminals primarily target stationary devices because they present the highest potential for stealing valuable patient data in large quantities.

What is medjacking and how does it pose a threat to healthcare organizations?

Medjacking, also known as medical device hijacking, is a serious cybersecurity issue that puts healthcare organizations at risk. It involves hackers compromising networked medical devices, including consumer health monitoring devices, wearables, embedded devices, and stationary devices, which are all connected to the internet.

One of the primary reasons why medjacking poses a threat is the valuable patient health data that these devices contain. Stationary devices like medical x-ray scanners and chemotherapy dispensing stations are particularly vulnerable, as they hold sensitive information that cybercriminals can exploit. In fact, medical data carries a higher value in the black market compared to credit card data, making these devices an attractive target for hackers.

The main factor contributing to the vulnerabilities in medical devices is the lack of security prioritization from manufacturers. These devices often do not come with strong built-in security measures, making them easy targets for hackers. Furthermore, the use of cyber defense tools is limited when it comes to medical devices, increasing the security risk.

Making matters worse, the government has not taken strong action against manufacturers or enforced strict security measures to mitigate these risks. This lack of regulatory pressure leaves healthcare organizations more exposed to potential medjacking incidents.

Another challenge in addressing medjacking is the difficulty in patching and fixing vulnerabilities in devices that are constantly in use. Healthcare organizations rely on these devices for critical functions and may face logistical challenges in implementing necessary security updates.

The consequences of medjacking can be severe for healthcare organizations. They are at risk of violating HIPAA regulations, which can lead to legal and financial penalties. Additionally, data breaches resulting from medjacking incidents can have serious implications for patient data security and confidentiality.

To combat the threat of medjacking, healthcare organizations should take proactive measures. This includes remediating infected devices, seeking fixes and updates from manufacturers, consulting with HIPAA experts to ensure compliance, evaluating vendors with a strong focus on cybersecurity, managing device access, isolating devices in secure network zones, and properly disposing of outdated devices.
