Smart Home IoT Cybersecurity Survey: A Systematic Mapping

Integrating Internet of Things (IoT) technology in smart homes has brought about significant automation and convenience advancements. Smart Home Internet of Things (SHIoT) is a technology where various intelligent devices communicate and share information, providing home comfort and convenience. However, with the increasing connectedness of devices, the potential for cyber-attacks and data breaches also increases. The increasing popularity and adoption of Smart Home IoT devices have brought about new challenges in cybersecurity. This systematic literature review aims to identify and analyze the current state of cybersecurity in SHIoT, including the threats and vulnerabilities faced by these devices and the existing countermeasures for securing them. A total of 50 studies published between 2016 and 2022 were evaluated, identifying several critical threats to SHIoT devices, including unsecured communications, lack of device security, and weak authentication mechanisms. Vulnerabilities in these devices include weak or hard-coded passwords, insecure software updates, and a lack of encryption. Finally, the countermeasures establish encryption, firewall, secure communication protocols, and authentication and access control to improve global security.
