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.

Blue Goat has a long-standing record of providing reliable and precise Software Bill of Materials (SBOMs) for its clients for over ten years. We have developed sophisticated tools that enable us to identify components, even at the snippet level, accurately. With our advanced string search algorithms, we can effectively detect all third-party and commercial components. Additionally, Blue Goat offers a comprehensive SBOM-as-a-service solution, which ensures that clients receive complete and accurate SBOMs in standard formats such as SPDX and CDX, which comply with the FDA's requirements. Moreover, Blue Goat can validate internally generated SBOMs or those created by their software supply chain partners, guaranteeing alignment with FDA regulations. By leveraging out expertise and tools, Blue Goat can play a crucial role in assisting organizations to generate reliable and 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:

  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.

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 fortify cybersecurity practices and enhance 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 robust 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.

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.

Over the past few years, the Internet of Things (IoT), coupled with the ubiquitous nature of Information Technology, has resulted in an ever-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 enhance patient safety and healthcare workers' treatment delivery. From medication administration to remote sensor monitoring, embedded medical devices are improving the quality of care and increasing interaction with their providers. While this technology was created with good intentions, the lack of security in product design phases is a major concern that will likely materialize into malicious action with grave 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 fortify 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 their ongoing efforts in enhancing 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.

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 robust security measures.

Inadequate security controls in medical devices have long been a pressing 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. Introducing new regulations and the potential for costly fines for non-compliance have made it clear that the days of overlooking security are over.

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.

Traditional cyber defense tools are not compatible with network connected medical devices for several reasons. Firstly, these devices often lack the necessary infrastructure to support the installation and operation of security tools. Unlike standard computers or mobile devices, medical devices have limited processing power, memory, and storage capacity. This makes it impractical, if not impossible, to run resource-intensive security software on such devices.

Additionally, applying any software modifications to these medical devices could be perceived as tampering and may potentially impact their 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 it challenging to enhance their security post-production.

Furthermore, traditional security tools are typically designed to protect more conventional systems and networks. They may not have been specifically developed or adapted to address the unique vulnerabilities and intricacies associated with medical devices. As a result, these tools may not effectively identify and mitigate the specific threats targeting medical devices, leaving them vulnerable to cyberattacks.

Given the critical nature of medical devices and the potential risks posed by cybersecurity breaches, it is important for manufacturers to integrate proper security tools directly into the design and production of these devices. This would ensure that they are secure from the outset and comply with FDA regulations.

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.

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.

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 robust 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, exacerbating the security risks.

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.

Medical device software testing is a critical process aimed at ensuring that software embedded within or designed to control medical devices functions accurately, reliably, and in compliance with regulatory standards.

  • Compliance Testing: Ensures the software meets all relevant regulatory and industry standards, focusing on safety, quality, and reliability requirements specific to medical devices.

Medical device software testing follows a rigorous methodology that includes planning, requirement analysis, test case development, execution of tests, and thorough documentation throughout the testing cycle. This methodology is designed to identify and address any defects or anomalies in the software architecture, code, or performance before the device reaches the market, thereby ensuring the safety and efficacy of medical devices. The process involves a combination of automated and manual testing techniques and requires a deep understanding of both the technical and regulatory aspects of medical device development.

Common medical device vulnerabilities encompass a range of issues that can compromise the safety, privacy, and effectiveness of medical devices. These vulnerabilities are often related to software flaws, outdated operating systems, or insecure interfaces, which cyber attackers can exploit to gain unauthorized access, steal sensitive data, or disrupt device functionality. Some of the most prevalent vulnerabilities include:

  • Insecure Network Connections: Many medical devices connect to healthcare networks via Wi-Fi or Bluetooth, making them susceptible to eavesdropping or unauthorized access if they are not properly secured.
  • Outdated Software and Firmware: Devices running on outdated software or firmware are vulnerable to known exploits that have not been patched. This includes operating systems that are no longer supported by their vendors.
  • Weak Authentication and Authorization Controls: Insufficient authentication mechanisms can allow unauthorized users to gain access to medical devices, potentially leading to misuse or the alteration of critical healthcare information.
  • Lack of Encryption: Failure to encrypt sensitive data both at rest and in transit can expose patient health information (PHI) and other confidential data to interception and misuse.
  • Third-Party Software Components: The use of vulnerable third-party software components can introduce additional risks, as device manufacturers may not always regularly update or patched these components.
  • Configuration and Customization Errors: Improper configuration or customization of medical devices can leave them open to attacks. This includes default passwords never changed or security features that are disabled for convenience.
  • Physical Security: Physical access to medical devices can also pose a threat, especially if devices are not adequately secured within the healthcare facility, allowing for tampering or theft.

Addressing these vulnerabilities requires a comprehensive cybersecurity strategy that includes regular software updates and patches, strong encryption methods, robust authentication and authorization controls, and vigilant monitoring of network connections. Additionally, collaboration between device manufacturers, healthcare providers, and cybersecurity professionals is essential to ensure the ongoing protection of medical devices against emerging threats.
