: In recent years, Internet of things (IoT) has gained a lot of attention while describing non-traditional devices connections. The non-traditional devices can be a medical equipment, a factory machinery, or the domestic appliances linked through internet to collaboratively perform a task. Extensive review on elements of architecture, IoT features and development, their key application is given by various researchers in which it is majorly observed that the IoT vendors pay lesser importance to the security and privacy aspect that leads to the situation where IoT exists with number of security/privacy vulnerabilities. For exchanging information, Internet has been used in IoT and sensing devices are connected. In order to achieve content aware and intelligent IoT systems location information acts as one of the most crucial aspects as the breach of security and privacy of the location information eventually discloses the real-world identity of the user. A large amount of localization or positioning functions are realized, however the privacy and security threats related to IoT positioning has not been addressed much. In this paper, we present a comprehensive review on various aspects of IoT security, security challenge, describe different attacks associated to it. Major focus is given over currently affected areas by various attacks.
