Enhancing Industrial Network Security and Reliability with Next-gen LAN Firewalls

In today’s connected world, cyberattacks on critical infrastructure are increasingly common. Industries like power substations, transportation, and water treatment face a constant risk of disruption. These attacks can have severe consequences, affecting both businesses and the daily lives of citizens.

As governments worldwide strengthen regulations around critical infrastructure security, industries are forced to adopt robust cybersecurity frameworks. The EU’s NIS2 Directive, for example, will require compliance by October 2024. To meet these standards, organizations must deploy solutions that not only secure their networks but also ensure operational continuity.

Addressing Key Concerns in Industrial Network Security

1. Network Design Changes

Integrating new devices, such as firewalls, often requires altering network topology and reconfiguring IP subnets. This can cause significant downtime, especially for critical applications. A firewall solution that doesn’t disrupt existing configurations is crucial.

2. Impact on Network Performance

Introducing new devices may affect performance, causing issues like longer boot times or increased latency. Network downtime is a major concern, particularly when critical services are involved. A solution that maintains optimal performance while enhancing security is essential.

3. Protection for Legacy Devices

Many industrial assets, especially legacy devices, are not easily updated to meet current security standards. A firewall that supports these devices, without the need for frequent updates, is key to maintaining security without disrupting operations.

4. Monitoring and Alerts

Constant monitoring is necessary to detect and respond to cyber threats quickly. A firewall solution with effective real-time alerts and management tools ensures that administrators can act swiftly to prevent downtime and damage.

Maximizing Network Security and Uptime with Moxa’s EDF-G1002-BP Series

Our EDF-G1002-BP Series industrial LAN firewalls are designed to address these challenges, enhancing network security without compromising uptime. Here’s how:

• Simplified Installation:

The EDF-G1002-BP operates in transparent firewall mode, allowing for quick and easy installation without the need for IP subnet reconfiguration. This means minimal disruption to existing network structures.

• Optimized Uptime:

With a boot time of just 30 seconds, our firewalls ensure rapid recovery after power outages, reducing the risk of operational disruptions. The LAN Bypass function further ensures continuous service, even during hardware or software failures.

• Legacy Device Protection:

Our firewalls incorporate IPS (Intrusion Prevention System) and DPI (Deep Packet Inspection) technology to safeguard legacy devices. These devices, such as PLCs and HMIs, are protected with virtual patches and pattern-based security, offering additional time to update legacy systems without exposing them to cyber threats.

• Simplified Network Management:

Moxa’s MXview One and MXsecurity software make it easy to manage your firewalls and network security. These tools provide real-time alerts, centralized control over firewall policies, and efficient event management, helping to streamline operations and reduce human error.

With the EDF-G1002-BP Series, you can achieve the network security and operational reliability your industrial network demands.
