A new wave of gadgets is setting out to secure your smart home

Rob Verger for Popular Science:  October 21, 2016, was a rough day on the internet. Dyn, a company that provides domain-name services, was hit by a distributed denial-of-service attack (DDoS). Perhaps you tried to visit sites like Twitter or Reddit and found that they didn’t work—that’s because of the attack on Dyn. The siege utilized a botnet, an exploit in which devices are co-opted to work towards a sinister goal, like flooding a specific website with traffic. In this case, the botnet was called Mirai.
A botnet requires a multitude of devices, and there are plenty of those connected to the internet already. Consumers around the world will hook up an estimated 5.2 billion “things” to the internet this year, and over 12 billion by the year 2020. Some of the things on that vast network are devices like printers or webcams, and some of those were swept into the Mirai botnet attack.
Incidents like that, or the more recent WannaCry ransomware attack, understandably turn people’s attention to the security of their home networks, especially if their cadre of devices includes things like baby monitors or security cameras.
“You look at the increasing complexity of someone’s home network,” Shuman Ghosemajumder, the CTO of cybersecurity company Shape Security, says. “And there’s a lot to remember in terms of: how do you secure that network as effectively as possible?”  Full Article:
