Security and privacy in the internet of things

The internet of things (IoT) is a technology that has the capacity to revolutionise the way that we live, in sectors ranging from transport to health, from entertainment to our interactions with government. This fantastic opportunity also presents a number of significant challenges. The growth in the number of devices and the speed of that growth presents challenges to our security and freedoms as we battle to develop policies, standards, and governance that shape this development without stifling innovation. This paper discusses the evolution of the IoT, its various definitions, and some of its key application areas. Security and privacy considerations and challenges that lie ahead are discussed both generally and in the context of these applications.
