Is Your Security Following Your Architecture, or Driving It? Insights for Industrial IoT

As a senior advisor in industrial IoT, I’m often asked by insurance executives: “Where is the risk in IIoT?” Their consensus is that connecting devices simply amplifies danger, so security can’t be part of the solution.

While the IoT introduces unprecedented attack vectors—take the Jeep incident where a hacker accessed the tire‑pressure monitoring system—modern industrial systems have evolved far beyond that fragile state.

Today, most legacy plants relied on “eggshell” firewalls or air‑gap isolation. That defensive posture has shifted dramatically. Security is now a core design principle rather than an afterthought. In fact, the pace of cyber‑security investments in industrial settings outpaces the rate of new cyber‑attacks. The net effect is a real decline in the likelihood of successful compromises.

Insurance partners often see this optimism as naive. In reality, the status quo still presents unacceptable risk. Entire sectors—oil & gas, utilities, manufacturing—continue to operate with minimal safeguards. The stark reality is that the known threats we face today far exceed the unknown future risks. Yet, the IIoT is precisely the catalyst that forces a new architecture, and with it comes built‑in security.

Industrial systems rarely adopt a new architecture solely for safety reasons. The power grid, for example, has raised the issue of security for two decades but has not yet re‑architected its control layers. The IIoT changes that calculus by demanding that new, data‑centric solutions also be secure. Consequently, security is no longer optional; it becomes a gatekeeper for modernization.

Beyond strategic motivation, technical progress is closing the gap. Data‑centric architectures—such as publish‑subscribe or peer‑to‑peer models—solve scalability and integration hurdles by delivering data where it is needed in real time. The trade‑off is a higher surface area for attacks.

Fortunately, the DDS standard now offers a security framework that dovetails with its data flow design. The result is a “data‑centric dog” whose tail is a perfectly matched security layer that preserves transparency while preventing compromise.

“Let’s send data directly to its destination. This makes the system fast, reliable, and easy to code.”

“But we can’t maintain thousands of secure sessions. How do we keep such a system safe?”

That question—once a barrier to IIoT adoption—has been answered by standards that align security with architecture. These advances are industry‑wide and promise a future where industrial IoT is far more secure than today’s ad‑hoc patches.

Insurance executives may still worry, but the real game‑changer is safety engineering. Advanced driver assistance systems (ADAS) and autonomous vehicles are projected to reduce road accidents by more than 90%, potentially erasing a $200 billion auto‑insurance market in the next decade. In healthcare, hospital errors—currently the third leading cause of death in the U.S.—can be dramatically reduced by automated, error‑free processes. Factories, refineries, and mining operations similarly benefit from removing human error from high‑risk tasks.

Disruption is inevitable, yet it offers a pathway to greener, safer, and more profitable futures. Navigating this transition successfully will be decisive for insurers and all other stakeholders. The IIoT’s economic impact is expected to reach multiple trillions of dollars within a few years.
