What is the Internet of Things?
Internet of Things (IoT) – is the network of physical objects integrated and embedded with electronics to connect with each other and the Internet. The IoT is a giant network of connected things and people – all of which collect and share data about the way they are used and about the environment around them. That includes an extraordinary number of objects of all shapes and sizes – from smart microwaves, which automatically cook your food for the right length of time, to self-driving cars, whose complex sensors detect objects in their path.
The first IoT device, developed in 1990, was a toaster that could be turned on and off over the internet. The term “internet of things” was coined in 1999 by Kevin Ashton
How does it work?
The whole concept of the Internet of Things is based on continuous data acquisition and analysis. Devices and objects with built in sensors are connected to an Internet of Things platform, which integrates data from the different devices and applies analytics to share the most valuable information with applications built to address specific needs. These powerful IoT platforms can pinpoint exactly what information is useful and what can safely be ignored. Smart objects and systems mean you can automate certain tasks, particularly when these are repetitive, mundane, time-consuming or even dangerous.
State of the Art
Nowadays, the IoT notion has evolved to include the perception of realizing a global infrastructure of interconnected networks of physical and virtual objects. The huge technological development has expanded the idea of the IoT to involve other technologies such as Cloud computing and Wireless Sensor Networks. The IoT has become able to connect both humans and things anywhere, and anytime, ideally using any path/network.
In 2017 Internet of Things (IoT) devices rose to prominence as attackers have continued to target and use them to support various cyberattacks. IoT devices sit on internal networks, have their own IP address, and allow communication with other internet connected devices and systems. The problem with IoT devices is that they have little security and are virtually unprotected. They typically don’t run standard operating systems that support the commonly used information technology security tools or just don’t have enough memory for them. IoT devices are also being used to establish “backdoors” for cyberattacks. Once attacker malware can be propagated into an IoT device, it almost is impossible for standard network security systems to identify these backdoors before they can be used to support attacker reconnaissance and the theft of data, diversion of funds, or the destruction of important infrastructure.
- The IoT is growing rapidly and has numerous applications and benefits
- Applications include: smart homes, municipal WiFi networks, smart grids, and supply chain management
- A network growing in size and complexity might rise questions of security and feasibility
