A review on Secutity in Internet of Things

Internet of Things (IoT) enables massive interconnectivity and interoperability between devices. With the growing number of devices, higher level of information exchange between the connected entities becomes possible. However, at the same time the sensitive information pertaining to the nodes becomes prone to security and privacy attacks. This is a serious topic in the IoT due to the large number of interconnections. In this paper, the detailed layer wise security vulnerabilities are enumerated. The security architecture of the IoT is presented. The solutions to the possible security attacks are detailed which will be a helping hand for the researchers working in this direction. The current state of the operational technology (OT)security is included.
