Review on security and privacy concerns in Internet of Things

Internet of Things (IoT) is associate degree rising conception which can interconnect billions of devices (such as smartphones, sensors and alternative networking devices), to speak with one another. IoT may be a system wherever objects embedded with detector technology to act with one another over wireless communication medium to come up with, exchange and transfer knowledge without human interaction. This interconnection is relevant in many ways like timely coordination with many simple devices such as sensors, thermostats, fitbits, routers etc. Due to open and heterogeneous nature of these networks, they are highly prone to vulnerable attacks. So privacy and security is the biggest concern in this technology. This paper focuses on common IoT vulnerabilities like Distributed Denial of Service (DDoS), Data modification attacks in background section. It covers privacy and security concerns in different segments like web interface vulnerabilities, device connections, spamming, data storage issues, IoT network related problems like Sybil attacks, cloud connectivity considerations, Industrial IoT attacks. There have been many privacy preserving mechanisms discovered (like Learning Automata based solution, disabling Universal Plug and Play, DDOS ALERT mechanisms, Rigorous Testing etc.) and related research is still going on. The goal of this paper to present the security and privacy concerns that IoT environment is facing and existing mechanisms to protect it.
