The Internet of Things (IoT) is growing exponentially. But security and privacy concerns are piling up at the same time. How can we understand where this trend is heading? Here's what we can learn from the history of the cloud.
IoT. Everybody is using it — whether they know it or not.
From smart home assistants to smart city parking and from walking robots to flying drones, millions of new devices are placed online every week. This new "Internet of Everything” is growing in breadth, depth and width of new offerings.
And yet, hackers seem to be laughing all the way to the bank.
So where are these trends heading? How can we connect the latest IoT security dots?
To start, check out these recent technology magazine headlines and IoT security report summaries:
Here is an excerpt from the IoT Security report from Pepper.me, which focused on how economics is driving a “race to the bottom” with IoT pricing focused on winning market share.
Ever feel like you’ve seen (a slightly different version of) this movie before?
I certainly do — and the evolving events remind me a lot of the developments in cloud security — only IoT security seems to be almost a decade behind.
A Brief History: Where Have We Been with IoT Security?
Rather than rehash some familiar IoT security topics, here’s a quick recap on IoT security highlights over the past few years, which include smart city security stories which are a piece of the Internet of Things. Notice the progression in IoT security themes.
This webinar was from 2016, which identified many early IoT security challenges. But we still face most of the same IoT issues today.
Three IoT Security Trends to Watch as We Head into the 2020s
As we look to industry answers to IoT security challenges, we can learn from the processes, solutions and organizations that have led the global cloud security challenges. Groups like the Cloud Security Alliance, which was founded in 2008, can help. We can learn from the roads they traveled, and the decisions that led to where we are today.
Also, the federal cloud developments with the FedRAMP program, offer an important track record worth considering. I describe more recent cloud security developments in this piece from 2018.
Here are three specific areas to watch as we head toward 2020:
1) Interoperability Standards — Consider this quote from RFID Journal: Are Smart Cities Secure?
“More troubling is that the interoperability standards specified in the new smart-city tenders were minimal. There were the primary syslog and SIEM requirements, but no STIX/TAXI, XML/JSON or similar to pass or consume threat intelligence data. I can understand an agency's systems sending alerts and data to an SOC, but not the need to receive any data back. It could be argued that related agencies will use the same systems, but the tender process may prevent that. That is why it is essential to document and require all necessary interoperability standards.”
NIST has been working on smart city and other IoT standards, and this video shows some of the ways.
Also, NIST has sponsored the Global Cities Team Challenge (GCTC), which I describe in more detail in this piece.
2) Data Breach Trends and IoT Missteps are Driving IoT Product Change — and Vendor Action
Consider these quotes from an article at IOTforall.com:
“The gap between companies that are the most security-savvy about the Internet of Things (IoT) and those that are the most security-challenged is huge, according to a recently released 2018 State of IoT Security Survey. That chasm has led to costly security missteps. …
The bottom-tier companies pointed to a few particularly troublesome spots. In comparison to top-tier companies, bottom-tier companies are:
Another key question will be whether more government regulations are coming for IoT in the near future. If there is a big mistake, such as a death related to insecure IoT, more regulation will happen quickly.
3) Competing Platforms — IoT platforms — everyone seems to be developing one.
This article from Network World attempts to show why they are so confusing. IoT for All, meanwhile, says: “IoT platforms are the support software that connects everything in an IoT system.” In this model, IoT platforms:
… Back in 2017, IoT Analytics compared a whopping 450 IoT platforms. (That number was up from 260 in the firm’s 2015 analysis and 360 in 2016. But though leading products are growing at more than 50 percent a year, the market remains highly fractured.)”
If we are looking to the cloud journey for answers on IoT security, will a CASB-like model emerge for IoT? Probably, or something very similar. No doubt, the competing platforms will play into this trend, and there are already security tools that will help enterprises find rogue IoT devices.
Let me be clear that we will be in this IoT security battle for a long, long time. There are NO SIMPLE ANSWERS that work in every situation. No doubt, the RSA Conference in San Francisco will be dominated by IoT Security in 2019 — and throughout the 2020s.
So if you want to connect the dots on where IoT security is heading — look to the road traveled by cloud security. Not all the answers are there, but the road will be similar in many respects as we try to establish reliable standards and overcome threats from evolving cyberattacks.
And yes, both cloud security and IoT security journeys continue to evolve. It is just that the cloud is a bit further down the yellow brick road.
