Operating Rail Infrastructure at Network Scale

Infrastructure managers operate the safety-critical rail systems every operator depends on, spanning signaling, power, communications, and control centers across vast networks. Cybersecurity must focus on network-wide resilience, not isolated systems.

Challenges

The Main Challenges in Securing Infrastructure Manager OT

Infrastructure spans vast, heterogeneous environments

Rail infrastructure often stretches across regions or countries and includes equipment deployed over decades, from legacy relay-based interlockings to modern RBCs (Radio Block Center) and digital signaling. Maintaining consistent visibility and security across this diversity is difficult, especially when assets evolve incrementally, creating a mix of serial and IP-based systems rather than through centralized redesign.

Multiple operators and stakeholders share the same infrastructure

Infrastructure managers must support access for Train Operating Companies (TOCs), maintenance contractors, and technology vendors, each with different operational needs and security postures. This shared responsibility increases exposure and makes it harder to attribute activity or assess risk without a unified operational view.

Failures and incidents propagate beyond a single site

A cyber issue affecting the Centralized Traffic Control (CTC) can have cascading impacts across lines, operators, and services. Incident response must prioritize system stability. Teams must coordinate across organizational boundaries, often under regulatory and public scrutiny.

OUR Solution

How CylusOne Empowers Security Operations for Infrastructure Managers

Consistent Visibility Across the Rail Network

CylusOne empowers infrastructure managers to maintain a consistent, network-wide understanding of their OT environment. By continuously discovering assets and mapping communications, from object controllers to field devices, it provides a baseline of zones/conduits, interdependencies, and operational trust boundaries.

Maintaining Control in Shared Environments

CylusOne empowers teams to manage shared access without losing control. It surfaces anomalous activity introduced through vendor remote access, maintenance sessions, or operator interfaces, helping infrastructure managers validate that interactions with core systems (like route setting requests) remain within approved operational boundaries.

Coordinated Response Across the Rail Network

CylusOne empowers coordinated, rail-safe response at infrastructure scale. By presenting incidents in an operational context and supporting integration with existing SOC processes, it helps teams assess impact, prioritize action, and contain issues in a way that protects safety-critical infrastructure while minimizing disruption across the wider rail network.
