LPS partnered with the railway operator to design and implement a holistic OT security framework focused on protecting operational integrity while enabling future digital growth. 

The project began with a comprehensive assessment of the physical and digital environments, reviewing network architecture, device configurations, and access controls. It included OT security risk assessment, design review, and consulting to ensure the systems comply with internal railway standards and international frameworks such as IEC 62443 and CLC TS 50701. A secure network segmentation strategy was implemented to establish multiple protection zones that effectively isolate critical control systems from less trusted environments. 

An Industrial Demilitarized Zone (IDMZ) architecture was introduced to control data exchange between corporate IT and OT systems, ensuring continuous communication without exposing essential rail operations. Field devices such as controllers and remote units were hardened through updated configuration standards and stronger authentication. 

Beyond infrastructure works, the operator expanded its driver training environment, introducing updates to its cab simulation system. To create an integrated security culture, LPS aligned physical and cybersecurity processes under a unified governance model and provided a vendor management template to ensure future procurements adhere to international railway cybersecurity standards.
