DoS Attacks in Internet of Things

Abstract

The Internet of Things (IoT) defines a highly interconnected network of heterogeneous devices where all kinds of communications seem to be possible, even unauthorized ones. As a result, the security requirement for such network becomes critical whilst common standard Internet security protocols are recognized as unusable in this type of networks, particularly due to some classes of IoT devices with constrained resources. Due to the limitations of energy, computation and storage for sensors, although IoT have been widely deployed in many applications such as military, ecological and health-related areas. It is a critical challenge to present the effective and lightweight security protocol to prevent various attacks for IoT, especially for the denial of service (DoS) attack. Normally, the adversaries compromise sensors and launch the DoS attack by replaying redundant messages or making overdose of fake messages. In this paper, we explore the scope of the DoS attack problem in IoT. First we outline the constraints, security requirements, and then explore types of DoS attacks in IoT.
