IEC 61162-460:2018

Overview

IEC 61162-460:2018 is an international standard that extends IEC 61162-450 to address higher safety and security needs for maritime Ethernet interconnections supporting multiple talkers and multiple listeners. This 2018 (Edition 2.0) technical revision specifies requirements and test methods for equipment, network design, interconnection to other networks, and redundant network configurations. It does not change application-level protocols already defined in IEC 61162-450.

Key topics and technical requirements

• Scope and purpose
  • Add-on to IEC 61162-450 for environments with higher exposure to external threats or where improved network integrity is required.
  • Defines requirements for both devices and the network (including interconnections and redundancy).
• Network components (logical & physical)
  • Definitions and requirements for 450-Nodes and 460-specific components: 460-Node, 460-Switch, 460-Forwarder, 460-Gateway, 460-Wireless gateway.
• Traffic management
  • Resource allocation, loop prevention, traffic prioritization and separation to maintain deterministic behavior in maritime data distribution.
• Security
  • Internal and external security requirements, firewall and access-control guidance, communication security for gateways and wireless access, and controls for connections between secure and non-secure areas.
• Redundancy
  • Requirements for interface and device redundancy, and for redundant IEC 61162-460 network topologies to improve availability.
• Network monitoring
  • Network status, load, topology and redundancy monitoring functions; standardized alert identifiers; syslog recording and alert management.
• Testing and conformity
  • Detailed test methods and required results for devices, switches, forwarders, gateways and the controlled network, enabling verification of compliance.

Notable technical changes in Edition 2 (2018):

• IGMP snooping required for 460-Switches and 460-Forwarders.
• 460-Forwarder mandatory as isolation between secure and non-secure areas.
• SFI collision detection added to network monitoring.
• 460-Gateway and 460-Wireless gateway no longer required to report to network monitoring.
• Standardized alert identifiers for all network monitoring alerts.

Practical applications and who uses it

• Shipbuilders, maritime equipment manufacturers and system integrators implementing Ethernet-based bridge and bridge-adjacent networks.
• Marine electronics vendors producing 460-compliant switches, forwarders, gateways and wireless gateways.
• Naval architects, classification societies and ship operators specifying network safety, redundancy and cybersecurity controls.
• Maritime cybersecurity and IT teams responsible for secure interconnection between shipboard networks and external systems.

Related standards

• IEC 61162-450 (base standard for Ethernet multiple talkers/listeners) - IEC 61162-460 is a safety/security add-on and does not replace application-level protocol requirements in 61162-450.
