IOT Security: Recent Trends and Challenges

Abstract

AbstractThe use of Internet of Things (IoT) devices is increasing day by day along with the increased use of advanced technologies in almost every field. IoT provides technologies like Wireless Sensor Networks (WSNs) and Radio Frequency Identification (RFID) which are used in several applications like forest fires, home automation, military equipment, traffic signals, medical sciences, agriculture, etc. Large amount of information is being obtained by the sensors and then sent to data centers through the transceivers for analysis and decision-making purposes. Based on these decisions, the actuators perform a particular tasks based on the applications. This large amount of data can be used by a third party for malicious purposes, so there is a need for information security almost at every level of IoT. IoT is the kind of technology that involves several fields of computer science at step. With the usage of multiple technologies like Artificial Intelligence, Machine Learning, Data Mining methods, etc., there is a need to provide proper security to the IoT system also. Several layers used in the IoT architecture need to be protected. Hence, there is a need to make a robust system in order to deal with the existing vulnerabilities, threats, attacks, and privacy and security challenges existing in IoT system. This paper discusses the recent trends in the IoT architecture along with acknowledging the threats present in different architecture layers. Along with this, the security threats and challenges are also discussed.KeywordsInternet of Things (IoT)Threats and securitySensors
