Abstract

One of the goals of smart environments is to improve the quality of human life in terms of comfort and efficiency. The Internet of Things (IoT) paradigm has recently evolved into a technology for building smart environments. Security and privacy are considered key issues in any real-world smart environment based on the IoT model. The security vulnerabilities in IoT-based systems create security threats that affect smart environment applications. Thus, there is a crucial need for intrusion detection systems (IDSs) designed for IoT environments to mitigate IoT-related security attacks that exploit some of these security vulnerabilities. Due to the limited computing and storage capabilities of IoT devices and the specific protocols used, conventional IDSs may not be an option for IoT environments. This article presents a comprehensive survey of the latest IDSs designed for the IoT model, with a focus on the corresponding methods, features, and mechanisms. This article also provides deep insight into the IoT architecture, emerging security vulnerabilities, and their relation to the layers of the IoT architecture. This work demonstrates that despite previous studies regarding the design and implementation of IDSs for the IoT paradigm, developing efficient, reliable and robust IDSs for IoT-based smart environments is still a crucial task. Key considerations for the development of such IDSs are introduced as a future outlook at the end of this survey.

Highlights

Incredible developments in the routine use of electronic services and applications have led to massive advances in telecommunications networks and the emergence of the concept of the Internet of Things (IoT)
Researchers study the security challenges of the IoT from many different points of view, one of which is the security vulnerability of IoT communication protocols [32]. This survey focuses on intrusion detection system (IDS) for the IoT paradigm, independent of any specific protocol; this study focuses on the security challenges facing IoT systems on the basis of the Institute of Electrical and Electronics Engineers (IEEE) definition and the general IoT architecture
According to the recommendations in recent surveys of IDSs for IoT systems [3, 7], this paper focuses on the features of all IDS methods for the IoT that can be applied in smart environments

Summary

Introduction

Incredible developments in the routine use of electronic services and applications have led to massive advances in telecommunications networks and the emergence of the concept of the Internet of Things (IoT). The IoT paradigm has recently been used in creating smart environments, such as smart cities and smart homes, with various application domains and related services. Wireless communication techniques, and IPv6 assist in the expansion of smart environments. Such environments are wide ranging, from smart cities and smart homes to smart healthcare and smart services. IoT systems are susceptible to various security attacks, such as denial-of-service (DoS) attacks and distributed denial-of-service (DDoS) attacks. Such attacks can cause considerable damage to the IoT services and smart environment applications in an IoT network. On Friday, October 21, 2016, a series of DDoS attacks were launched across the US that exploited the security vulnerabilities in IoT systems [6]
