Tech Student, Computer Science and Engineering, Uttarakhand Techinical University, PremNagar, Sudhowala, Dehradun, Uttarakhand, India Online published on 24 October, 2019. Abstract The Internet of things aspires to connect anyone with anything at any point of time at any place. Internet of Things is an emerging technology across the world, which helps to connect sensors, vehicles hospitals, industries and consumers through internet connectivity. As Internet of Thing is of three-layer architecture, IoT security principles should be enabled at each layer for the proper and efficient working of these applications. Internet of Things has so many applications in today's day to day life like Home automation, Healthcare, Smart grid, Smart car etc. The intrinsic vulnerabilities of IoT devices, with limited resources and heterogeneous technologies, together with the lack of specifically designed IoT standards, represent a fertile ground for the expansion of specific cyber threats. This paper briefs the motivation for IoT, privacy, threats, challanges, IoT applications, security issues with various security solutions and challanges and opportunties for IoT. Top Keywords Internet of Things, security issues in IoT, security, home automation, healthcare, intrinsic vulnerabilities. Top |
