| A. RELATED SURVEYS AND OUR CONTRIBUTIONS
There are various existing surveys on IoT security and pri- vacy issues. Yuchen et al. [10] have summarized various security issues in IoT applications. Authors of [11] have dis- cussed the security issues specific to location-based services in IoT. The authors target the particular problems related to localization and positioning of the IoT devices. Anne et al. in [12] focus mainly on the security issues related to IoT middleware and provide a detailed survey of related existing protocols and their security issues. M. Guizani et al. in [14] have surveyed various trust management techniques for IoT along with their pros and cons. Security mechanisms for IoT security such as software defined networking (SDN) and network function virtualization (NFV) are discussed in [13]. In [8] the authors have compared edge computing with traditional cloud systems to secure IoT systems. Jie Lin et al. in [9] have discussed the relationship between IoT and fog computing. Some of the security issues related to fog computing have also been discussed. Authors of [7] have discussed vulnerabilities faced by IoT in brief. Table 2 summarizes the main contributions of the previous compre- hensive surveys on IoT security. Although there are several works in this direction, they are specific to certain limited aspects of IoT. This calls the need for a detailed survey on all the existing and upcoming security challenges in IoT applications. This paper will help the reader to get a detailed idea of the state-of-the-art in IoT security and will give them a general understanding of the area. The main contributions of this work are as follows: 1. A classification of different IoT applications and spe- cific security and privacy issues related to those appli- cations. 2. A detailed explanation of different threat sources in different layers of IoT. 3. Detailed and realistic recommendations to improve the IoT infrastructure to facilitate secure communications. 4. Review on the proposed countermeasures to the secu- rity issues in IoT. 5. An assessment of the open issues, challenges and future research directions for developing secure IoT applications. B. ORGANIZATION The organization of the rest of the paper is as follows: Section II describes various application areas of IoT where high security is required. Section III discusses various sources of threats in an IoT environment. In section IV various con- straints and requirements to be considered while developing a secure IoT application are reviewed. Four major IoT se- curity approaches, i.e., blockchain, fog computing, machine learning, and edge computing are presented in Section V, VI, VII, and VIII, respectively. Section IX describes various open issues, challenges and upcoming research opportunities in IoT security and finally, Section X concludes the paper. tải về 6.16 Mb. Chia sẻ với bạn bè của bạn:
