A vital role will be played by the “Internet of Things” in the future. Everything linked to the internet has an individual identity and is capable of interacting with other devices on the internet, thanks to the global network architecture that underpins the “Internet of Things” (IOT). A "thing" in the “Internet of Things” paradigm is one that has been combined with electronic components such as software, sensors, and a network connection. A number of communication infrastructures may be used to transmit data between these "things" and servers, centralized systems, and/or other linked devices. The internet is used to transfer IoT data from sensors, nodes, and collectors to a cloud server. Customers, healthcare professionals, companies, and the government all rely on IOT devices in their daily lives. It is predicted that there will be 31 billion IOT devices in operation worldwide by 2020. Vulnerabilities related to the IOT are on the rise as the number of devices rises. Based on studies, the IOT paradigm faces new security problems due to broad use and integration with new technologies. This article contains future research on IOT security issues and open questions.
