By using an integrated approach, we link research between user characteristics. Perceived Risk and contextual factors in determining safety practices. These research findings highlight the growing awareness of the importance of IoT security. But there is a significant gap between awareness and action. Many individuals display limited knowledge and security measures are used infrequently. They often rely on default settings and neglect to update. Additionally, technical expertise Perceived Risk and contextual factors influence safety behavior. From these insights We propose a proactive, user centric framework. with an emphasis on tailored education User friendly security solution and share common responsibilities to promote a secure IoT ecosystem.enInternet of Things (IoT)Cyber SecuritySecurity AwarenessBehavior ChangeUser-Centric SecurityRisk PerceptionSecurity PracticesEmpirical InvestigationMixed Methods ResearchIoT AdoptionVulnerability ManagementThreat ModelingData PrivacyUser EducationThesis
