Abstract	The rapid expansion of Internet of Things (IoT) technologies has created interconnected environments in which sensors, smart appliances, industrial devices, medical equipment, vehicles, and digital platforms continuously exchange information. While connected devices provide significant opportunities for automation, monitoring, and intelligent services, their distributed architecture also introduces substantial cybersecurity risks. This study examines IoT security frameworks for protecting connected devices, with emphasis on device authentication, authorization, secure communication, data protection, access control, vulnerability management, network security, threat detection, and security lifecycle management. A qualitative descriptive and conceptual research design was adopted using secondary academic literature. The analysis indicates that effective IoT security requires a multilayered framework extending from device hardware and firmware to communication networks, gateways, cloud platforms, and applications. Authentication and authorization mechanisms can restrict unauthorized access, while encryption can protect information during transmission and storage. Secure software updates and vulnerability management can reduce risks associated with outdated device components. Network monitoring and intelligent threat detection can provide additional protection against emerging attacks. However, resource constraints, heterogeneous devices, interoperability limitations, inadequate security standards, privacy concerns, and large-scale deployment complexity continue to challenge IoT security. Recent research also emphasizes the absence of comprehensive security approaches covering all IoT layers and the need for stronger assessment and benchmarking mechanisms. The study concludes that secure-by-design architectures, lifecycle-based protection, standardized security requirements, adaptive monitoring, and risk-based security management are essential for protecting future connected-device ecosystems.
