A Framework for the Integration of Safety and Security in the IoT

The proposed framework for integrating safety and security in Internet of Things (IoT) systems addresses the complex interplay between these two critical aspects of system design. By recognizing that security vulnerabilities can directly impact safety and that safety hazards can create security risks, the framework takes a holistic approach to risk mitigation. This integrated perspective is particularly crucial in IoT environments, where interconnected devices and systems often operate in sensitive or critical contexts, such as healthcare, transportation, or industrial control systems. The framework’s utilization of analytical tools like Fault Tree Analysis (FTA) and Attack Trees (AT) provides a structured methodology for identifying potential failure modes and attack vectors. This systematic approach enables developers and system architects to anticipate and address vulnerabilities proactively, rather than reactively responding to incidents. Furthermore, the inclusion of a structured remediation and validation process ensures that identified risks are not only recognized but also effectively mitigated and tested. This comprehensive cycle of analysis, remediation, and validation is essential for creating IoT systems that are both secure and safe, capable of maintaining reliability and trustworthiness in the face of evolving threats and operational challenges.
