Protecting Station BMS

Station Building Management Systems (BMS) control HVAC, lighting, access control, and other environmental systems that support passenger safety and comfort. These systems operate in public-facing environments and increasingly rely on IP connectivity and centralized control, making them part of the rail OT security landscape.

Challenges

The Main Challenges in Securing Station BMS

BMS environments are exposed and highly accessible

Station systems operate in public spaces and often interface with contractors, facility management platforms, and city infrastructure. This exposure increases risk and complicates control.

BMS technologies vary widely by station and age

Systems are often deployed incrementally, resulting in mixed protocols, vendors, and control models across a single network.

Disruption affects safety and passenger experience

Failures in environmental or access systems can impact evacuation, crowd management, and station operations, even if train service continues.

OUR Solution

How CylusOne Secures Station BMS Systems

Establishing Baseline Behavior for Station Building Systems

CylusOne secures station BMS by monitoring operational communications across environmental and facility control systems without interfering with building operations. It builds an understanding of normal system behavior across stations and usage patterns.

Detecting Risk in Facility Control Interactions

CylusOne identifies anomalies that may indicate cyber risk, misconfiguration, or unintended interaction with other systems via the BMS gateway. By presenting these deviations in an operational context, it helps teams assess potential impact on station safety and functionality.

Maintaining Safe and Reliable Station Environments

CylusOne supports coordinated response by connecting BMS security events to the broader rail OT environment. This enables teams to protect station systems proactively while maintaining safe, reliable passenger spaces.
