Mohammad Rezaul Karim, Sohag Kabir, Ci Lei, Raluca Lefticaru · 2025
The interaction between Internet of Things (IoT) safety and security, as conceptualized within the CIAS (Confidentiality, Integrity, Availability, and Safety) model, presents a complex and multifaceted challenge that necessitates a comprehensive approach. The CIAS model extends the traditional CIA triad by incorporating safety as a fourth pillar, thereby acknowledging the essential role of physical safety in IoT applications. It is crucial to balance security requirements with the real-time and reliability demands of safety-critical IoT applications. This paper explores the intricate interaction between safety and security in the context of the IoT, emphasizing the need for a comprehensive approach to address these critical aspects and the importance of ongoing research and collaboration to navigate the challenges in this domain.
