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.

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.
