The paradigm of Internet of Things alludes to the ever- growing network of physical devices that is embedded with sensors, actuators, software and networking so that the devices can exchange information with centralized systems, connected devices or servers based on various communication infrastructures. The IoT data is transmitted over the internet to the cloud after collecting it from different sensors and nodes. While the number of devices connected to the internet is rising every day, several IoT vulnerabilities have come to the forefront. Therefore, security and privacy for resource-constrained IoT devices is a foremost important issue to resolve. The architecture of IoT mainly operates on a three-layer system consisting of a perception layer, an internet layer, and an application layer. The main aim of IoT security is to maintain confidentiality, integrity, data privacy, provide the user security along with the acceptable quality of service. This paper will analyze the security issues and possible attacks related to each layer of IoT architecture separately. Vulnerabilities of Message Queue Telemetry Transport, the application layer protocol has also been analyzed.
