Abstract

Internet of things is a growing technology with many business opportunities and risks. It is strongly believed that IoT will cause a major shift in people's lives similar to how the internet transformed the way people communicate and share information. IoT is becoming popular in the various domains such as smart health, smart cities, smart transport, and smart retail. The security and privacy concerns of IoT are crucial as it connects a large number of devices. Security is a more critical issue that certainly needs to be resolved with a high level of attention, as with an increasing number of users, there would be a need to manage their requests and check authenticity on the cloud-based pattern. Recently, a series of massive distributed denial-of-service attacks have occurred in IoT organizations. Such malicious attacks have highlighted the threats resulting from not enough security in IoT devices together with their overwhelming effects on the internet. This chapter provides an overview of the security attacks with regard to IoT technologies, protocols, and applications.

Iot Architecture

The architecture of IoT is included with the recent technologies of communication protocols, sensors and RFID like devices. The architecture can be typically represented by four interconnected layers or entities namely Acquisition layer, Network layer, Support layer or Middleware layer and Application layer as represented in Figure 1.
