Industrial Cyber Secure Computing for Critical Infrastructure

Industrial environments face increasing threats from cyberattacks targeting control systems, data flows, and network availability. Cyber secure computing platforms help protect operational technology (OT) by integrating industrial-grade hardware with built-in security features. These solutions are designed to safeguard edge computing, data acquisition, and control operations, even in harsh environments.

Assistance with NIS2 Compliance

Using IEC 62443-compliant computers supports NIS2 compliance by strengthening industrial cybersecurity and aligning with its risk-based security requirements.

Cyber Secure Computing For Your Application: Where Our Solutions Work

Substation Automation and Smart Grid Networks

Substation Automation and Smart Grid Networks

Substations are prime targets for cyberattacks due to their critical role in national grid stability. Secure data acquisition, control logic, and remote monitoring must all be protected from intrusion. IEC 62443-compliant computing devices help safeguard communication between IEDs (Intelligent Electronic Devices), SCADA systems, and control centers by enabling secure boot, encrypted data handling, and access control. These standards also support compliance with NERC CIP and IEC 61850 integration.

Railway Signalling and Control Systems

Railway Signalling and Control Systems

Modern rail systems use distributed computing for signalling, track monitoring, passenger information, and communications-based train control (CBTC). An attack on these systems can cause service disruption or safety hazards. IEC 62443 compliance is essential to ensure that embedded computers managing edge data are protected from tampering or malicious access.

Oil & Gas Pipeline Monitoring

Oil & Gas Pipeline Monitoring

Pipeline infrastructure relies on edge computing to monitor flow rates, pressure, and leak detection across remote sites. These systems often communicate over public or semi-secure networks, making them vulnerable to interception or manipulation. Deploying IEC 62443-compliant industrial computers enhances cybersecurity by incorporating device hardening, secure communication protocols (e.g., MQTT with TLS), and remote access control. These systems also align with industry safety standards such as ATEX and C1D2 when used in hazardous zones.

Smart City Infrastructure (Traffic, Utilities, Surveillance)

Smart City Infrastructure (Traffic, Utilities, Surveillance)

Smart cities use thousands of distributed endpoints to manage utilities, traffic signals, lighting, and public safety systems. These nodes must be protected against cyber threats, especially as they collect and transmit real-time data to central cloud platforms. IEC 62443-compliant computing solutions ensure each node has the necessary safeguards like signed firmware, firewall capabilities, and intrusion logging. Compact, fanless computers with wide temperature tolerance are perfect for street-level deployment.

Frequently Asked Questions

What does it mean if a computer is IEC 62443-4-2 certified?

  • IEC 62443-4-2 outlines technical security requirements for individual components, such as embedded devices and industrial computers. A computer certified to this standard includes security features like secure boot, user authentication, data encryption, and audit logging. Certification ensures the device has been tested against rigorous criteria for cybersecurity in OT environments.

How does IEC 62443 benefit system integrators and end users?

  • For system integrators, IEC 62443 provides a structured framework for designing secure automation networks. For end users, it offers assurance that computing devices meet stringent cybersecurity standards. This reduces risk, simplifies compliance audits, and supports long-term system stability.

Is IEC 62443 compliance mandatory?

  • IEC 62443 compliance is not always legally mandated, but it is increasingly referenced in regulations, procurement specifications, and international standards. For example, the EU’s NIS2 Directive recommends adherence to IEC 62443 principles to ensure cybersecurity best practices.

Can legacy industrial systems be upgraded to meet IEC 62443?

  • While older systems may not meet IEC 62443 out of the box, they can be upgraded using secure computing gateways, network segmentation, and industrial firewalls. Devices like the MOXA UC-8200 can act as secure front-ends for legacy equipment, adding encrypted communication, access control, and intrusion detection without replacing the entire system.

How do I verify that an industrial computer meets IEC 62443 standards?

  • Look for documentation such as product datasheets, certification reports, or third-party test results that reference IEC 62443-4-2 compliance. Manufacturers like MOXA publish security white papers and guarantee compliance through partnerships with accredited testing laboratories.
