IoT is an extreme speed technology comprises of smart things or objects that communicate with one another and ease the job of our daily life. The most common applications of IoT are smart homes, wearables, connected cars, smart cities, smart retail, agriculture, healthcare etc. It is a big revolution in the history of the Internet. Things that connect to the Internet have a lot of chances of potential risks. The IoT applications use sensitive data that is more susceptible to attacks, so we have to compromise the security. Beginning with introducing the IoT model and communication protocols, this paper surveys several security attacks at each layer of IoT model and corresponding countermeasures to protect such a huge heterogeneous network.
