A Survey of Security in Internet of Things – Importance and Solutions

Background: Internet of Things (IoT) has the potential for societal, environmental as well as economic impact. This comes with a huge responsibility, that of securing all the communications, data and participating things. Method: Surveys and comparative studies are used for understanding the security in IoT. Findings: This paper surveys the IoT at the architectural and protocol stack level. We outline an effective architectural and stack level restructuring. The integration issues at the IPv6 enabled Low Power Wireless Personal Area Network (6LoWPAN) layer along with the security challenges and existing solutions are discussed and summarized under the chosen parameters. These parameters are Privacy, Authentication, Confidentiality, Denial of Service (DOS) Protect, Replay Protect, Impersonate Protect, End-to-End(E2E) Security.
