The Internet of Things (IoT) sounds a bit mysterious.
As more devices are equipped with the ability to connect online and even to each other, opportunities—and potential security pitfalls—abound.
Dupaco Community Credit Union’s Camilo Ruiz, a network security analyst, helps explain IoT—and how it impacts you.
Today, devices everywhere are connected to internet.
Thermostats, light bulbs, sound systems, refrigerators, smart TVs, health care devices, automotive devices, watches and so many other devices can connect online or to one another.
“All those devices, created with the main purpose of improving the quality of life, have in common that they are connected to internet,” Ruiz says. “So, all of these devices that send and receive data constantly are called Internet of Things.”
More than 8.4 billion such “things” were in use worldwide last year, according to the analyst company Gartner. That figure is expected to soar to 20.4 billion by 2020, with Cisco estimating there will be 3.4 connected devices per person that same year.
Why are so many devices being connected?
Forbes contributor Jacob Morgan explains the potential that IoT offers:
“What if your alarm clock wakes up you at 6 a.m. and then notifies your coffee maker to start brewing coffee for you? What if your office equipment knew when it was running low on supplies and automatically re-ordered more?”
The possibilities, it seems, are endless.
But with billions of connected “things” worldwide, created by thousands of companies, the greater the risk of hackers gaining access to your information, Ruiz says.
For instance, hackers could use a smart TV to gain access to your personal information. But you can reduce your risk by using a protected network (see more below).
The IoT encompasses certain health care devices too. If you or someone you know needs a heart pacemaker, and you have the option to use a wireless one, it’s important to ask thorough questions about the security of the device, Ruiz cautions.
“It sounds like science fiction, but nowadays it is technically feasible to compromise these devices remotely, and this is the reason many patients and doctors are making the decision to disable the wireless function of the device to reduce the risks,” he explains.
For your personal devices, which are connected to your home network, it’s important to follow the same security measures recommended for computers:
Pro tip: Passphrases are more secure and easier to remember than passwords.
