We are in the booming phase of the Internet of Things (IoT) and, with it, beginning to be aware of the security risks it is vulnerable to. These historical IoT security hacks should give us some perspective: Between 2006–2010, attackers created the Stuxnet virus, designed to damage Iranian centrifuges by targeting their SCADA systems. In 2013, hackers were able to exploit and utilize millions of IoT devices to create a botnet. More than 25% of the zombies in the botnet were made up of devices like smart TVs and baby monitoring systems. In 2015, researchers hacked into a running JEEP’s computer system, managed to engage/disengage the brakes, and cut the driver off his own car.
In our previous posts, we discussed sensors and wireless communications—the two components that underpin the Internet of Things technology. Our current post looks at how these technologies take effect in real life and help make a difference to operations. Two of these cases deal with real-time location systems (RTLS) implemented in healthcare and logistics and the other with condition monitoring in wind farms. (more…)
The Internet of Things would not be the exciting prospect that it is without a key component – wireless technologies. These technologies are defined under various standards and protocols and choosing the right one depends on the context and the requirement.
Some IoT implementations require data to be transmitted over long distances, others short; some devices transfer small volumes of data, others large. Some are deployed in inaccessible environment and their life needs to be sustained longer. This diversity in requirements and devices necessitates different communication standards and protocols in different contexts.
Twenty eight years ago, the Internet took over the world by storm and turned it to the global village we know today. Enter the Internet of Things, and there are more sentient objects in that village—8.4 billion as per Gartner. Everything from industrial pumps and wind turbines to self-driving cars and household appliances now share the digital space with us. By 2020, their number is set to touch 20 billion.
