What Is An Industrial Firewall Used For?

Industrial firewalls are crucial for maintaining the security and operational efficiency of industrial environments. They are specifically designed to withstand harsh conditions and provide resilient protection for sensitive machinery and control systems.

Key industrial firewall applications include:

• Network Segmentation: Industrial firewalls enable the creation of segmented networks, isolating critical operational technology (OT) from IT networks and other less secure areas. This prevents the spread of malware and restricts unauthorised access to vital industrial processes.
• Deep Packet Inspection (DPI): Unlike traditional firewalls, many industrial firewalls incorporate DPI capabilities that understand industrial protocols. This allows them to identify and block malicious code embedded within legitimate industrial communications, preventing sophisticated attacks.
• Intrusion Prevention Systems (IPS): Integrated IPS functionality helps to detect and prevent known cyber threats in real-time by constantly monitoring network traffic for suspicious patterns and signatures. This proactive defence is essential for maintaining the uptime of industrial operations.
• Remote Access Security: For remote monitoring and management of industrial assets, firewalls secure VPN connections, ensuring that only authorised personnel can access the network from outside the facility. This is vital for maintaining secure connectivity to remote sites.
• Data Diode Functionality: Some advanced industrial firewalls can offer data diode functionality, allowing data to flow in one direction only. This is particularly useful in highly sensitive environments where it’s critical to prevent any potential backflow of data from less secure networks into the OT network.
