When it comes to security, IoT technology can cut both ways. It can, for instance, protect against terrorist attacks and shootings. One connected technology—body cameras—is leading to unprecedented oversight of law enforcement. Connected technology also enables law enforcement to detect the location of gunshots near instantaneously and to keep tabs on car accidents using automatic crash notification data. IoT technology can also be used to monitor fires and people facing medical emergencies and natural disasters. It can be used to monitor that warning lights on roads or at railroad crossings are functioning correctly. There are countless ways that IoT can improve public safety.
“Security goes both ways because there are a lot of applications of IoT products that are about increasing security and there are also concerns about what happens if that data gets out,” says Particle CEO Zach Supalla.
For instance, it may be a valid concern to worry about a personal security camera feeds being hacked. But modern security cameras have better security protocols in place. “I think part of this concern comes from an era that has already passed where IoT devices were not secure by default,” Supalla says.
Still, the security of many connected devices developed five to ten years ago seems scary by today’s standards. “There are a lot of things out there that are totally insecure, and I don’t mean poorly implemented encryption—I mean things that no one thought to encrypt in the first place,” Supalla explains.
There are also Internet sites that catalog default username and passwords for video cameras for various manufacturers. But many video cameras simply broadcast their signals publically without their owner’s knowledge, making it possible for anyone to logon to a site like www.shodan.io and view their video feed in real time. The site includes live camera feeds of everything from baby cribs to people sitting in front of their computer. On Shodan, non-password-protected camera feeds of public and private places abound.
“But those are mostly cameras that were installed in the last ten years,” Supalla says. “New devices are much more secure—more often than not.”
The Internet of Things industry is making progress in addressing security. “These days, people have kind of figured out that security matters and that we have to lock stuff down,” he explains. Most buyers also have some understanding that security is a priority. “We know a lot about security risks and how to address them. It just doesn’t feel that way because there is so much legacy equipment out there.”
