Background:
In the maritime industry, Voyage Data Recorders (VDRs) serve as the vessel’s equivalent of an aircraft’s black box—capturing critical navigation data, communications, and sensor input. These systems are not only mandatory under SOLAS Chapter V, Regulation 20, but are also essential in incident investigations and operational performance monitoring.
Yet as ships become more connected, cybersecurity risks to VDR systems are growing. Unprotected network access points can expose VDRs to data tampering, unauthorized access, or even full system compromise.
The Challenge: Protecting VDR Systems in a Connected World
VDR systems often require remote maintenance or integration with broader vessel IT systems. But these connections can create security vulnerabilities if not managed correctly—potentially exposing the ship’s most sensitive data to outside threats.
Introducing the MG460 Gateway - A IEC61162-460 Compliant Maritime Solution
Robustel’s MG460 Gateway (also available as a wireless model) is a purpose-built IEC 61162-460 cybersecurity gateway for maritime Operational Technology (OT). Designed to protect onboard equipment like VDRs from cyber threats, it offers marine-certified, DNV-approved network protection that aligns with IEC 60945 environmental standards and 460 network compliance.
How does the MG460 Gateway Secure VDR Systems?
- Maritime-Grade Firewall with Deep Packet Inspection
The MG460 goes beyond basic firewalls—it understands maritime-specific protocols (NMEA, IEC 61162) and inspects them in real time. - Secure Demilitarized Zone (DMZ) for Data Access
A secure DMZ zone acts as a controlled buffer between external access points and the VDR system—allowing safe file transfers. - Isolated Network Segmentation
With 5 independent Gigabit Ethernet ports, each with its own firewall configuration, the MG460 Gateway allows complete VDR network isolation. - Legacy Compatibility with Serial Interfaces
Includes dual configurable serial ports (RS232/RS422/RS485) to secure legacy equipment without expensive retrofits. - Full Logging and Audit Trail
All access attempts and traffic patterns are logged locally with microSD storage, ensuring full auditability.
Solution Architecture
Real-World Scenario: Securing Both Legacy and New VDR Installations
Whether securing legacy Simplified VDRs (S-VDRs) or modern full-featured VDR systems, the MG460 Gateway provides a scalable, standards-compliant solution. Older vessels built before July 2002 may operate S-VDRs that lack integrated cybersecurity features, while newer vessels still require a secure gateway to protect sensitive operational data and enable safe remote access.
By deploying the MG460 Gateway between the VDR and any network interface, vessel operators can:
- Add modern network security to legacy and new VDR systems
- Comply with IEC 61162-460 and maritime cybersecurity standards
- Enable secure remote support and diagnostics
- Protect critical recorded data from cyber threats
- Ensure investigation-readiness and operational integrity
Go Beyond Compliance: Business and Operational Advantages
While protecting VDRs is a regulatory requirement, integrating the MG460 Gateway into your solution architecture offers real-world operational value:
- Remote Maintenance: Encrypted VPN access for authorized engineers
- Secure Data Extraction: Enables analytics and performance reviews
- Future-Proof Cyber Architecture: Supports firmware updates to protect against evolving cyber threats
- Universal Compatibility: The MG460 Gateway's compatibility with maritime standards ensures it works harmoniously with VDR systems from all major manufacturers.
