In the scientific community, the Internet of Things (IoT) is the latest buzzword. We live in an age where Internet access is not only possible for the vast majority of the population, but also increasingly affordable. The number of gadgets with internet access and built-in sensors continues to rise. Indeed, the prevalence and prevalence of smart phones, and the use of such devices, are on the rise. With this idea, anybody can hook up any device to the web. However, a major security issue will arise from the practise of storing and communicating data with anyone and any device. It's also unclear how well data can be transferred, communicated, and shared in this setting. In this paper, we discuss concerns about IoT security, including those of privacy, reliability, and accessibility. The rapidly evolving applications made possible by the IoT have drastically altered daily life, making it feel more fantastical and akin to living in a virtual world. Due to its open nature, the Internet of Things (IoT) might pose significant security challenges. A variety of methods, including encryption, are employed to protect the information transmitted by IoT devices.
