The growth of IoT (Internet of Things) in smart homes is transforming how we interact with our living spaces, offering enhanced convenience, automation and control. The technology grows rapidly so the security must also be high. The paper explores the current state of IoT-enabled smart home systems, security vulnerabilities, risk assessment models and user-centered solutions. Common threats like hacking, data breaches, phishing, malware, encryption, authentication and intrusion detection are discussed. One study introduces CRASHED [cyber risk assessment for smart home electronic devices]; these systems are based on structured data and reasoning rather than using AI or ML to detect and respond to threats more intelligently. It can also be implemented in a practical and cost-efficient manner. A voice-controlled smart home model using sensors and network-based automation is presented. It includes Wi-Fi, 4G, 5G, with results showing how improved connectivity enhances system responsiveness and reliability.
