Internet of things (IoT) is a new revolution that uses Internet services to connect to the entire world anywhere, at any time without restricting geographic location. It provides a platform for communication between objects, self-regulation and identification by radio frequency identification (RFID), the ZigBee network, the wireless network, etc. for efficient communication. The unique features of this technology provide the dynamic nature, connectivity, massive scale, heterogeneity, sensor power, etc., which have the ability to improve various innovative applications and services. However, the IoT structure provides a complex environment that has many difficult problems such as connectivity, power, power and other security,which must be resolved. The success of the Internet of things depends on a security problem that protects users' personal data from threats in real time. But many of the security mechanisms already used in the traditional network are no longer enough to protect the next generation of the Internet from things. This article reviews several security attacks and their countermeasures on the three levels of the Internet of things. Initially, we provide an overview of each level of the Internet of things with applications and challenges. After that, we discuss different attacks and countermeasures for each layer. Finally, we analyze network routing attacks, which are more powerful attacks that can degrade the Internet performance of things.
