Abstract
Nowadays, people live amidst the smart home domain, while there are business opportunities in industrial smart cities and healthcare. However, there are concerns about security. Security is central for IoT systems to protect sensitive data and infrastructure, whilst security issues have become increasingly expensive, in particular in Industrial Internet of Things (IIoT) domains. Nonetheless, there are some key challenges for dealing with those security issues in IoT domains: Applications operate in distributed environments such as Blockchain, varied smart objects are used, and sensors are limited, as far as machine resources are concerned. In this way, traditional security does not fit in IoT systems. The issue of cybersecurity has become paramount to the Internet of Things (IoT) and the Industrial Internet of Things (IIoT) in mitigating cybersecurity risk for organizations and end users. New cybersecurity technologies/applications present improvements for IoT security management. Nevertheless, there is a gap in the effectiveness of IoT cyber risk solutions. This review article discusses the literature trends around opportunities and threats in cybersecurity for IIoT, by reviewing 70 key articles discovered from a profound Scopus literature survey. It aims to present the current debate around the issue of IIoT rather than suggesting any particular technical solutions to solve network security problems.
Highlights
The Internet of Things (IoT) aims to integrate the digital and physical universes into a distinct system, providing major business opportunities for several sectors such as industry, tourism, and energy
It focuses on the users’ susceptibility to cyber-attack, the way different factors mediates the relationship in IoT [40]; it elicits major threat drivers and identifies emerging technologies that are likely to have an impact on defense and attack capabilities in cybersecurity [16]
The IoT has been a key element for smart manufacturing, smart cities, smart health, smart grids, and electric vehicles (EV), for example
Summary
The Internet of Things (IoT) aims to integrate the digital and physical universes into a distinct system, providing major business opportunities for several sectors such as industry, tourism, and energy. It has created a new paradigm in which a network of machines and devices capable of communicating and collaborating with each other are driving new processes. The IoT is a system where the Internet is linked to the physical world through sensors [2]. The IoT is strongly related to manufacturing, in order to produce high-quality products at low cost by assembling the Industrial Internet of Things (IIoT), cloud computing, and big data analytics [7], including robots [8]
