IoT smart devices are part of a very lucrative market, and consumer IoT spending is set to reach somewhere around $62 billion this year.

The influx of connected devices from our lives is continually increasing, so it’s no surprise that IoT security was one of the leading topics at 2018 RSA Conference. Don’t get your hopes too high, because this doesn’t mean that there’s also any flawless viable solution involved for the moment.

IoT devices are plagued by security issues

John Cook, Symantec’s senior director of product management, spoke at RSAC as well, saying that:

A lot of the manufacturing behind IoT devices today feels like the Gold Rush… everyone wants to get there in a hurry. You effectively have people staking out a claim in the area without further thought to security.

After the 2016 Mirai botnet attack which was created as a distributed denial of service attack via 300,000 vulnerable devices such as webcams, video recorders and routers showed the horrible effect of the lack of security in IoT devices. Unfortunately, nothing has notably changed so far.

ESET’s Tony Anscombe proved this by spending tons of time testing 12 IoT devices and found more security issues from encryption problems to passwords that were stored in plain text. He also addressed the issue during the RSAC referring to privacy policy concerns.

IoT device manufacturers see security as too pricey

Unfortunately, manufacturers are currently looking at security as if it were a costly alternative to other factors that low-power connected devices need. According to Fitbit’s Marc Brown, lots of IoT manufacturers would always choose using low power cheaper chips instead of stronger ones that provide a higher level of security.

Manufacturers are trading off encryption for low power chips, lower prices, storage space, and battery life,” Bown said.

What can manufacturers do to enhance security

The first step that manufacturers should take for increased security ould be to understand how a device will be used and use that understanding afterward. Bown talked about threat modeling and about the fact that manufacturers have to think about all the situations in which devices can protect themselves. Symantec’s Cook added that the push for manufacturers to move their focus towards increased security needs to ultimately come from end users.
