Abstract
The Internet of Things (IoT) is a network of embedded devices that are uniquely identifiable and have embedded software required to communicate between the transient states. The purpose of this study is to explore discrete IoT security challenges pertaining to currently deployed IoT standards and protocols. We have presented a detailed review in this study that focuses on IoT's imminent security aspects, covering identification of risks pertaining to the current IoT system, novel security protocols, and security projects proffered in recent years. This work presents an updated review of the IoT architecture in the protocols and standards that are proffered for the next-gen IoT systems. A security-specific comparative analysis of protocols, standards, and proffered security models are presented as per IoT security requirements. This study elicits the need for standardization at the communication and data audit level, which exposes the hardware, software, and data to various threats and attacks. Our study reveals a need for protocols that are competent enough to be accorded for over one threat vector. This paper provides an insight into the latest security research trends, which will prove beneficial in the development of IoT security. The research outcomes can benefit the research community in IoT by integrating IoT-based devices' best security aspects.
Highlights
The entire network domain is undergoing a drastic technological revolution
To avert the modifications brought in the Internet of Things (IoT) devices through physical attacks, there is a provision of Physically Unclonable Function [67] protocols that are imbibed in the specially designed PUF chip mounted on the IoT devices
This work highlighted the recent security trends in the IoT network domain by surveying the newly proffered models, protocols, and encryption methods implied in securing the IoT network
Summary
Automation of networks has been a hot topic that has been trending for quite some time. Supplementing it is Internet of Things (IoT) technology, which paves the way for providing that element. Local physical devices connected to the internet for real-time data analysis were considered being the IoT network. Research works on IoT depict the proliferation of IoT in the field of–healthcare [3], industrial setup [4], business analytics, education, etc. As of 2019, IoT, which used to work at smaller network spaces, has upgraded for wide area networks, and so have the risks relative to it because of the expected surge in IoT devices in a diversified environment
