The Crucial Role of Security in IIoT Solutions

Written by Jordan Deville, Sr. ICS Consultant | OT Consultant


As the world continues to embrace digital transformation, industrial settings such as chemical plants and manufacturing facilities are not exempt from this transition. The emergence of Industrial Internet of Things (IIoT) technology has paved the way for enhanced automation, improved operational efficiency, and increased productivity in these environments. However, it is essential to address the critical aspect of security in IIoT implementations to ensure the protection of valuable assets and data.

In this blog post, we will explore the significance of security in IIoT and highlight the measures necessary to safeguard your industrial operations.

Physical Security

At the sensor level, physical security plays a crucial role in IIoT systems. Ensuring the separation of IIoT sensors from control system sensors is imperative to prevent unauthorized access or data manipulation. By implementing physical separation, damage to the overall integrity and reliability of the system, both control and IIoT, is minimized.

Network Security

Layered network security is vital in protecting IIoT systems. While general IT network security is typically layered on top of IIoT, it is essential to consider that IT network security systems are primarily designed for conventional data flow and authentication. In contrast, IIoT requires specific configurations that focus on control system data flow standards. IT network security systems may be updated every two to three years, while IIoT systems often span 15 to 20 years between updates. As such, there are many complexities that must be accounted for anytime the IT system needs an update. Therefore, it is crucial to bridge the gap between the two and ensure the security of both systems.

Cloud / Local Hybrid Infrastructure

Many IIoT systems require both cloud and on-premise server infrastructure to process and integrate data effectively. However, this integration introduces the challenge of establishing secure network tunneling between the different types of infrastructure. Virtual Private Networks (VPNs) or authentication using Transport Layer Security (TLS) certificates are both valid options. However, the latter requires more advanced configuration and regular IT maintenance. By implementing these measures, you can secure the data flow between cloud and on-premise servers in your IIoT system.

Data Security

The security design of a standalone IIoT system primarily involves focusing on user and system access control to prevent unauthorized entry. Additionally, the tag-level security provided and supported by most IIoT and Control System manufacturers can offer an added layer of protection. Integration with third-party systems, especially for data analysis, must be carefully controlled to ensure critical data remains adequately protected and does not fall into the wrong hands.

Control System Adjacent System Architecture

Well-designed architecture connecting an IIoT system with the primary control system is crucial to maintaining data security. It is essential to ensure that data is only produced by the control system and consumed by the IIoT system to prevent accidental data leakage or unauthorized data control. Likewise, data should not be allowed into the control system from the IIoT system. By implementing robust security measures, you can have full control over the data flow between these interconnected systems without compromising their integrity.

In the fast-paced world of industrial settings, staying ahead of the curve is essential. In our ongoing exploration of digital transformation, we’re delving deep into the powerful realm of the Industrial Internet of Things (IIoT) and how it can supercharge your existing control systems.

In the heart of every large industrial organization lies a sophisticated control system, silently orchestrating operations. However, extracting critical data from this system has often been a challenge, confined to a select few with specialized access. This data is the lifeblood of understanding the health and performance of your facility.

In the conventional scenario, departments relied on periodic reports from technical or operations teams to obtain this vital information. But what if there was a way to access real-time data, enabling more informed decision-making across various disciplines?

Realizing the Vision: Examples in Action

Consider a facility manager who yearns for real-time monitoring of output or the ability to track utilization, or maintenance personnel aiming to predict equipment maintenance by tracking downtimes. Picture the finance team seamlessly accessing live input and output data for precise sales and purchasing reports, or the reliability and environmental team effortlessly tracking energy usage for compliance and early detection of potential issues.

A Glimpse into the Past

Traditionally, this level of integration was a complex endeavor. Multiple SCADA systems were often employed to manage each of these tasks independently, if they were implemented at all. Without such systems, reliance on periodic reports from the Controls or Operations team was the only recourse.

IIoT: Bridging the Gap

Enter Industrial Internet of Things (IIoT), a transformative force in the industrial landscape. IIoT transcends the limitations of conventional approaches by harnessing data not only from the control system but also from a myriad of other sources, including databases, sales information, and even weather data.

Unlike traditional systems, IIoT operates separately from the main facility controls, with no capability to override existing systems. This separation from control network access means that it adheres to standard IT controls, ensuring a secure and manageable environment for user access.

In the past, SCADA expertise, complex licensing models, and the hardware and software infrastructure of traditional control systems proved to be technical and economic barriers for both large and small organizations that were considering enhancements to their industrial automation systems and remote operations capabilities. However, with technology ever evolving, the value of implementing remote asset monitoring and control often greatly outweighs the accompanying challenges. While cloud computing has been a mainstay in enterprise software for nearly a decade, the platform concept has become mature and secure enough to meet the demanding expectations of industrial operators. By offering a pay-as-you-go subscription model to avoid the large capital investment of deploying onsite infrastructure, hosted SCADA solutions can provide a lower cost of entry into remote operations monitoring, control and data analytics.

What is it?

A hosted, cloud-based, SCADA system is provided as a service and can be connected to a variety of processes at virtually any geographical location over a secure, private network. Operators can securely access and interact with their process data, potentially from any device anywhere in the world at any time.

With minimal network infrastructure deployed at the assets, a secure connection can be established with existing control system infrastructure. For organizations who are not yet automated but may be hesitant due to budget constraints, the cost savings of a hosted SCADA system can help by limiting capital investments to only control system hardware such as local operator interfaces, instrumentation, and installation. If assets are already automated via a control system, the move to SCADA in the cloud is simplified even further.

Security, performance, reliability and maintainability are common concerns when deploying onsite servers and network infrastructure. By offloading these functions to a cloud provider, asset owners can focus more on running an efficient and profitable business.

Another benefit inherent to a properly designed cloud-based SCADA solution is scalability. As assets are bought and sold, the system can be ramped up and down in a quick, efficient, and secure manner. Integrated cybersecurity, in combination with the flexibility of user and role-based access control, allows for specificity of access to applications for any combination of view, control, and configuration per asset. Subscribing to a hosted SCADA system also provides the experience, support, and the software and hardware upgrades that are best delivered via an external dedicated SCADA team with expertise servicing multiple standard and custom applications.
