The concept of the Internet of Things is defined by the desire to connect everything to everything at any time (IoT). The Internet of Things (IoT) idea encompasses not just enabling connectivity but also permitting interaction between these connected objects. Though the term" internet of things" was coined in 1999, it has received a lot of attention in recent years. The rate at which new gadgets are integrated into the system will have a significant positive impact on the world, but it will also pose substantial security and privacy risks.

In its current state, IoT is vulnerable to a wide range of threats. Because data is exposed to a variety of attacks by attackers at each tier of IoT, one of the most pressing challenges of IoT is to provide security assurance for data flow. The Internet of Things is organized in layers, with each layer providing a service. Because each layer serves a particular purpose, the security requirements change from one another. This paper is to examine the numerous security and privacy issues associated with IoT. The paper briefly describes a number of existing security mechanisms that operate at various layers.
