Move Safely. Operate Reliably.
SECURING RAIL & TRANSPORTATION SYSTEMS
We help rail operators and transit agencies protect signaling systems, train control, and passenger operations through comprehensive OT security aligned with TSA Security Directives and railway safety requirements.
"Rail and transportation systems depend on sophisticated signaling, train control, and operations management where cyber incidents can compromise passenger safety, disrupt service affecting millions, and create cascading impacts across transportation networks."
Rail & Transit Cyber Security Challenges
Passenger Safety, Service Reliability and Operational Continuity are paramount for rail and transit systems.
Rail and transportation systems rely on integrated safety and operations technology including positive train control (PTC), signaling and interlocking systems, automatic train protection and operation (ATP/ATO), centralized traffic control (CTC), and passenger information and ticketing systems. These systems coordinate train movements, prevent collisions, and manage passenger flow across complex networks.
The sector faces distinctive cybersecurity challenges: safety-critical signaling systems using specialized protocols, legacy infrastructure with decades-old equipment, operational requirements for 24/7 service reliability, geographically distributed assets across rail networks, increasing TSA regulatory scrutiny following security directives, and the need to balance safety system integrity with operational efficiency.
With TSA Security Directives mandating cybersecurity measures for rail and transit operators, demonstrated cyber attacks targeting transportation infrastructure, and the critical nature of signaling systems for passenger safety, rail operators must implement comprehensive OT security programs that protect both safety and service delivery.
Transportation Threat Environment
Rail-Specific Threats
- Signaling system manipulation causing false signals or unauthorized route changes
- Train control system attacks affecting automatic train protection and speed enforcement
- Ransomware disrupting operations management and passenger information systems
- Communication system compromise affecting train-to-wayside and dispatch communications
- Track infrastructure system attacks impacting switch controls and crossing protection
- Passenger facing system breaches affecting ticketing, gates, and security systems
Operational Consequences
- Passenger safety incidents from compromised signaling or train control systems
- Service disruptions affecting millions of passengers and causing economic impact
- Track closures and system-wide delays from safety system failures
- TSA Security Directive violations resulting in enforcement actions and penalties
- Emergency response coordination failures during incidents or disasters
- Public confidence erosion from publicized cyber security incidents

Rail & Transit Security Strategy
Safety-First, TSA-Compliant Approach
For rail and transit operators, OTFIELD provides cybersecurity programs that prioritize passenger safety while meeting TSA Security Directive requirements - recognizing that signaling and train control systems are safety-critical and require specialized security approaches.
We understand rail operational realities: signaling systems use specialized protocols not common in other industries, safety certification requirements constrain system modifications, operations run 24/7 with limited maintenance windows, infrastructure spans hundreds of miles with remote assets, and TSA compliance mandates are non-negotiable. Our approach delivers practical security within these unique constraints.
Comprehensive Rail Security Implementation
Phase 1: Safety-Critical System Assessment
Objective: Identify cyber risks to passenger safety and operational continuity per TSA requirements
- Assess safety-critical signaling and train control systems (PTC, ATP, interlocking)
- Evaluate traffic management and dispatch system vulnerabilities
- Review train-to-wayside communication system security
- Identify risks to track infrastructure controls (switches, crossings, detectors)
- Assess passenger-facing system security (ticketing, information, access control)
- Map TSA Security Directive compliance requirements and gaps
This assessment prioritizes controls protecting passenger safety and meeting federal regulatory requirements.

Rail & Transit Success Factors
Rail and transit operators must address these critical considerations:
- Can we secure signaling systems without compromising safety certification?
- How do we meet TSA Security Directive requirements within operational constraints?
- Are train control systems protected while maintaining fail-safe functionality?
- Can we segment networks without disrupting integrated operations?
- How do we manage security for geographically distributed rail infrastructure?
- Do we have incident response capabilities meeting TSA reporting timelines?
Success requires balancing safety system integrity with security controls in highly regulated transportation environments.
