Threat Model and Risk Management for a Smart Home IoT System.

The emergence of smart homes, driven by the rapid growth and development of technology, has brought numerous benefits to human life, including convenience and improved wellbeing. However, the incorporation of IoT devices into smart homes and their connection to the Internet have created new security and privacy challenges that affect the confidentiality, integrity, and availability of data collected and exchanged by these devices. Such challenges have led to security threats that render IoT devices in smart homes vulnerable to various vector attacks. To provide a comprehensive picture of the security of smart homes, this paper applies the STRIDE [1] threat model to identify potential threats at different layers, namely the IoT device, communication, and application layers. Additionally, a risk-rating security threat model, DREAD, is used to assess the risks of these threats. Finally, this paper proposes a risk mitigation strategy to respond to the rated risks and improve the security of smart home IoT systems. The primary aim of this paper is to enhance the understanding of the various security threats insmart homes and provide a security baseline to enhance the security of smart home IoT systems.
