IoT and SCADA Integration Concerns

SCADA Systems

While expanding the data collection capabilities of a water utility may seem like a simple idea, new technology always comes with some risk. Integrating SCADA with IoT requires careful planning to avoid unexpected consequences.

System Security

Linking a SCADA system to a broader network increases the vulnerability to cyberattacks. Traditional SCADA was an internal arrangement. Anyone hoping to hijack or interrupt the system needed to be on site.

A networked SCADA system has the same security weaknesses as the rest of the network. Unfortunately, this arrangement may mean that an intruder attacking the network through a security loophole in an unrelated department could access the control system, disrupting operations.

Human error is the most frequent cause of successful cyberattacks. An unsuspecting employee clicks on a link in an unsolicited email. A weak password or a stolen device offers easy access to the network.

Since water utilities are essential facilities, they must develop standard cybersecurity protocols. Some of the practices that maintain network safety include:

  • Two-step verification
  • Complex passwords
  • Mobile device protocols
  • Regular cybersecurity training
  • Cyberattack drills

Integrating Older SCADA Technology with a Cloud-Based System

Many water facilities already have SCADA systems running parallel to a wireless network. The age of this technology is a barrier to integration with a cloud-based SCADA system. If the facility cannot afford to update its SCADA sensors for direct communication, it must establish a databus or API to act as a bridge. If information cannot flow easily from SCADA technology to the more extensive network, it will lead to siloed data and lost opportunities for insight.

Choosing Relevant Data

The number of available sensors can lead to an unmanageable data pool. As managers set up the system, they must evaluate what data sets will best help inform operations or assess system health. While machine learning and AI tools can sift a remarkable amount of data, providing limits and guidance will improve efficiency.

Monitoring with Cloud-Based SCADA

Creating an IoT and SCADA Integration Plan

A helpful integration of IoT and SCADA will likely take two forms. With an existing SCADA system, a facility may incorporate the complete system as a single device in the network.

The information normally flows to the Human Machine Interface (HMI) and will travel to the larger network servers.

This arrangement will limit the number of possible connections to the devices in the SCADA system.

Newer facilities may build their SCADA equipment into a more extensive network. In this model, the individual devices in the SCADA system will be part of the wireless web.

This arrangement allows for more device-to-device communication, increasing flexible management possibilities.
