1.1 General

Many Personal Health Devices (PHDs) and Point-of-Care Devices (PoCDs) provide vital support for people living with chronic disease or experiencing a life-threatening medical event. Cybersecurity attacks on vulnerable devices may lead to the alteration of prescribed therapy (e.g., sleep apnoea breathing therapy, insulin therapy) or to information disclosure that results in insurance or identity fraud or in direct or indirect patient harm. Companies subject to a successful cybersecurity attack may suffer financial harm and a negative reputation. Manufacturers of regulated PHDs/PoCDs are required to address cybersecurity vulnerabilities through a detailed risk analysis of use cases specific to the device. Of the various approaches to vulnerability assessment, some are not repeatable, scalable, systematic, and auditable. Both manufacturers and regulatory bodies may benefit from a common approach to vulnerability assessment based on threat modeling capable of analyzing PHDs/PoCDs across domains and described in a trusted open consensus standard. Likewise, patients, providers, and payers benefit from consistent and sufficient information provided in PHD/PoCD labeling. This standard is based on the PHD Cybersecurity Standards Roadmap findings (IEEE white paper [B4]) and presents a repeatable, scalable, systematic, and auditable approach to vulnerability assessment.2 While a specific approach is provided, any comparable approach is appropriate and will be compatible with the mitigations found in IEEE Std 11073-40102™ [B3]. In Figure 1, this standard is depicted by the top row, and IEEE Std 11073-40102 is depicted by the bottom row. Figure 1 — Vulnerability assessment workflow
