Few software development life cycle (SDLC) models explicitly address software security in detail, so secure software development practices usually need to be added to each SDLC model to ensure that the software being developed is well-secured. This document recommends the Secure Software Development Framework (SSDF) — a core set of high-level secure software development practices that can be integrated into each SDLC implementation. Following such practices should help software producers reduce the number of vulnerabilities in released software, reduce the potential impact of the exploitation of undetected or unaddressed vulnerabilities, and address the root causes of vulnerabilities to prevent future recurrences. Because the framework provides a common vocabulary for secure software development, software acquirers can also use it to foster communications with suppliers in acquisition processes and other management activities.

In-patient service demands have increased during a time when patients have experienced reduced access to hospital care. Hospital-at-Home (HaH) solutions are a form of telehealth that provide an in-patient care experience in patients’ homes, offering the potential for improved outcomes. While these are desirable benefits, HaH involves privacy and cybersecurity risks by introducing hospital-grade medical or biometric devices and information systems outside the hospital’s direct control (i.e., the patient’s home). Patient homes increasingly feature Internet of Things (IoT) devices, such as voice assistants (e.g., smart speakers), as part of a broader “smart home” ecosystem. These devices may not have capabilities that support privacy and security practices and may be used as pivot points for attackers to gain access to a hospital’s information system. This paper introduces a notional high-level smart home integration reference architecture to better un
