Introducing the Internet of Things (IoT) changed the way one interacts with technology, and everything is networked from devices all over the world. IoT has made everyday things smart through embedding sensors, software, and connectivity to the internet. This allows the devices to collect and share data. With smart homes and intelligent industrial systems, IoT devices are in almost every space of human lives and businesses. This revolutionizing technology has unlocked unprecedented heights in convenience, efficiency, and automation but also laid down serious challenges to cybersecurity.
The Growth of IoT and Its Applications
It’s grown at a really rapid pace over the last decade. It is estimated that more than 20 billion IoT devices have already been installed all over the world, and this number of implemented devices is growing really fast.
Invariably, these devices find applicability in a number of sectors ranging from health care, manufacturing, agriculture, and logistics, among others, with each and every one of them using the technology for process optimization, value information retrieval, and an increase in productivity.
• Smart Homes: From now on, lighting, thermostats, and security systems can be controlled by smartphones or voice-controlled assistants even in households. However, all these facilities and securities also bring some types of new vulnerabilities.
• Healthcare: The industry of healthcare has harbored the IoT by wearing health parameter measuring gadgets, smart infusion pumps, and connected diagnostic equipment. Interconnected treatment is one of the advantages, but sensitive patient data at risk of breaching is also increased.
• Manufacturing: IoT has brought revolutions in the manufacturing process with predictive maintenance, smart machinery, and automation of the machines. That brings them to more efficiency but, at the same time, exposes the networks of manufacturing to cyber threats.
• Logistics: The other fields are applications of fleet management systems, smart warehouses, and connected shipping containers. These solutions are operational-efficient but, at the same time, pose threats from being used for disrupting supply chains.
• Smart Cities: Urban centers across the globe are getting smarter with networks of connected traffic lights, cameras, and utilities. This web of infrastructure interconnection holds the promise for improved city living but, at the same time, it introduces new cybersecurity concerns.
Cybersecurity Challenges in the IoT Landscape
With IoT devices, the field has expanded further for cybercriminals. The reasons for the latter group of vulnerability are provided below:
• Diversity of Devices: From simple consumer electronics to complex industrial machineries, IoT devices are all together different in terms of hardware specifications and software requirements. This kind of diversity makes it daunting to put up a unified cybersecurity framework.
