# Review of Smart-Home Security Using the Internet of Things
###### Abstract  
As the Internet of Things (IoT) continues to revolutionize the way we interact with our living spaces, the concept of smart homes has become increasingly prevalent. However, along with the convenience and connectivity offered by IoT-enabled devices in smart homes comes a range of security challenges. This paper explores the landscape of smart-home security. In contrast to similar surveys, this study also examines the particularities of popular categories of smart devices, like home assistants, TVs, AR/VR, locks, sensors, etc. It examines various security threats and vulnerabilities inherent in smart-home ecosystems, including unauthorized access, data breaches, and device tampering. Additionally, the paper discusses existing security mechanisms and protocols designed to mitigate these risks, such as encryption, authentication, and intrusion-detection systems. Furthermore, it highlights the importance of user awareness and education in maintaining the security of smart-home environments. Finally, the paper proposes future research directions and recommendations for enhancing smart-home security with IoT, including the development of robust security best practices and standards, improved device authentication methods, and more effective intrusion-detection techniques. By addressing these challenges, the potential of IoT-enabled smart homes to enhance convenience and efficiency while ensuring privacy, security, and cyber-resilience can be realized. s +

modern society. These services provide convenience, speed, and security, particularly in the context of smart homes. A study conducted by Cisco (2010) underscores the exponential growth of personal Internet-enabled devices. Specifically, in 2010, there were 12 billion connected devices; in 2015, there were 25 billion; in 2020, there were 50 billion; and it is projected that by 2035, the number of Internet-connected devices will reach 1 trillion. The IoT takes advantage of the growing trend of interconnected devices to offer a wide range of services through a single device, such as the user's mobile phone. However, managing and securing a home through IoT technology is a significant challenge due to the heterogeneous and independent technologies of the devices. Although there are numerous smart-home devices available that offer individual services to users, these devices must interact and cooperate with one another, which can be a major obstacle due to the different technologies and protocols they employ. This heterogeneity makes them vulnerable to attacks and creates an insecure environment. The ISO-27005 security protocol (2010) identifies the vulnerabilities of a connected-device environment that can cause a total system failure in terms of security, allowing malicious, unauthorized users to intrude into the network and gain access to all of the personal data and management services provided through the network remotely. In 2014, for example, videos from 73,000 Internet-connected cameras were leaked online, and in 2016, every Internet-connected device was attacked, on average, once every two minutes (2016). According to research by HP (2016), approximately 70% of smart devices are vulnerable to threats, and during the trial stage, 90% of the personal data collected during the installation of smart devices were intercepted. In this digital era within which we are living, technology is progressing at a fast pace and is interleaved within our daily activities. Modern cyber-physical systems are materializing new applications and are providing a way of living which would have seemed quite futuristic some decades ago. Smart homes, and smart spaces in general, are one such novel installation and the main focus of this paper. Advance automations, AI, assisting with living, safety, and even robotics and personalized healthcare, constitute some indicative use cases.
