Railway Cybersecurity

Securing the Connected Railway Ecosystem

Railways support passenger mobility, freight movement, supply chains, and national infrastructure. Dawon provides Asset Intelligence, threat detection, compliance and risk management, incident readiness and response across railway operations from signalling and traffic management to rolling stock, stations, depots, and passenger services.

The Railway Operating Environment

Connected Railways Create an Interdependent Security Environment

Modern railway operations depend on interconnected signalling, communications, rolling stock, traffic management, station systems, maintenance platforms, passenger services, and external suppliers.

Digital signalling, automated operations, predictive maintenance, wireless communications, remote engineering, and centralized traffic management improve capacity and efficiency. At the same time, they create new connections between operational technology, enterprise IT, cloud services, trains, stations, and third party networks.

A compromise in one environment can affect train movement, operational control, passenger information, ticketing, maintenance, freight services, or network availability.

What the environment imposes

  • Safety and Service Continuity

    Railway cybersecurity is directly connected to operational safety. Unauthorized access, configuration changes, communication disruption, or manipulation of operational data may cause delays, require precautionary shutdowns, or affect safety related functions.

    Security decisions must therefore account for passenger safety, train movements, engineering constraints, and service continuity.

  • Distributed and Long Lived Infrastructure

    Railway systems extend across tracks, stations, depots, control centres, communication networks, and moving trains. Many technologies remain operational for decades and cannot be easily patched, restarted, or replaced.

    Security must protect both modern connected systems and older infrastructure without disrupting railway operations or affecting safety.

  • Expanding Connectivity

    Connections between trains, wayside infrastructure, stations, operations centres, enterprise systems, and external services increase the potential attack surface.

    Remote maintenance and supplier access create additional risk when credentials, connections, and engineering activity are not consistently governed.

  • Complex Supplier Ecosystem

    Railway operators depend on rolling stock manufacturers, signalling providers, communications companies, maintenance contractors, software suppliers, and system integrators.

    Cybersecurity responsibilities and evidence must remain traceable across the complete supplier and operational lifecycle.

One Shared Security Context

Operational Intelligence Across Railway Operations

Dawon establishes a shared security context across fixed infrastructure, rolling stock, stations, operational control, and supporting services. This allows cyber events to be evaluated according to their potential effect on safety, service availability, and passenger or freight operations.

  • Asset Intelligence

    Develop continuously updated intelligence about operational systems, software, configurations, communications, ownership, location, and railway function. Dawon connects each system to the service or operational process it supports, creating a unified understanding of the railway environment.

  • Operational Dependency

    Map relationships between signalling, train operations, station services, maintenance environments, communications, enterprise systems, and external suppliers. Understand how disruption within one system or provider could affect wider railway operations.

  • Threat Detection

    Identify suspicious communications, unauthorized access, abnormal behaviour, credential misuse, unexpected data movement, and unapproved changes across railway environments. Dawon correlates technical activity with railway operations, helping teams focus on events that could affect safety or service continuity.

  • Safety Informed Risk Prioritization

    Prioritize vulnerabilities and exposures according to their potential impact on:

    • Passenger and workforce safety
    • Train movement and traffic management
    • Service availability and timetable continuity
    • Freight and supply chain operations
    • Recovery complexity
    • Regulatory responsibilities

  • Remote Access and Supplier Governance

    Connect remote activity to the responsible user, supplier, business purpose, approved period, and affected railway environment. This strengthens accountability while allowing authorized engineering and maintenance work to continue.

  • Incident Readiness and Response

    Coordinate cyber response with railway operations, engineering, safety, communications, and management teams.

  3. 03Assess Safety and Service Impact
  4. 04Coordinate
  5. 05Contain Safely
  6. 06Recover
  7. 07Preserve Evidence

Containment decisions account for train movements, passenger safety, engineering requirements, and the potential operational impact of disconnecting or isolating a system.

What the model covers

  • Infrastructure and Signalling

    Protect the operational environments responsible for train detection, route control, signalling, trackside communications, and network coordination.

  • Rolling Stock

    Maintain security intelligence across onboard control, communications, monitoring, diagnostics, and passenger service environments.

  • Stations and Depots

    Secure connected operational systems supporting station management, passenger services, maintenance, and depot operations.

  • Operations and Supporting Services

    Protect traffic management centres, engineering environments, enterprise applications, remote access services, and external connections supporting railway operations.

Design to Decommissioning

Security Throughout the Railway Lifecycle

Railway systems have long operational lifecycles, making it essential to integrate cybersecurity into design, procurement, commissioning, operation, maintenance, modernization, and decommissioning.

Decades in service
  1. Design
  2. Procurement
  3. Integration
  4. Commissioning
  5. Operation
  6. Maintenance
  7. Modernization
  8. Decommissioning

The first four stages are the only ones a railway passes through once. Everything after them repeats for as long as the line is open, which is why a security requirement written at design has to still be provable at the fourth modernization.

Dawon helps railway organizations

  • Establish cybersecurity requirements during design and procurement

  • Assess supplier and technology dependencies

  • Maintain trusted software and configuration baselines

  • Monitor operational activity and unauthorized changes

  • Manage vulnerabilities within safety and availability constraints

  • Govern contractor and remote maintenance access

  • Preserve evidence for assurance, audits, and investigations

  • Coordinate cybersecurity with railway safety management
