The present study aims to analyze cyber threats in the Internet of Things (IoT). A descriptive-analytical methodology based on library resources is used in this research. IoT security is a multidimensional subject requiring comprehensive solutions and coordination between manufacturers, policymakers, and users. Through more collaboration in this field, it is possible to transform IoT into a sustainable and secure ecosystem. Although IoT security challenges still exist, with collaborative efforts, we can turn it into a source of wealth to improve lives. Due to the resource limitations of IoT devices, it is difficult to implement strong security protocols. To solve this challenge, various security strategies should be employed, such as lightweight security protocols. The design of cryptographic algorithms compatible with the hardware and resource limitations of IoT devices should be considered by manufacturers.
