Therefore, to overcome this, IoT network must act towards effectively with the threats and also to make sure security and privacy of information that shared in a network. This paper gives an overview of the existing works on security and privacy challenges in the IoT network. In addition, the paper discusses the security attacks and privacy issues on IoT data. Hence, concern about privacy-preserving and security-aware is needed so that better protections shall be incorporated to make the massive IoT network to be a secured one.
