A modern railway is a highly electrotechnical system with connectivity and networks inherent in its design. For High Speed 2 this means a design which is based on a confluence of difference wired and wireless networks. These networks support the delivery of safety critical, safety related, operation critical and wider business functions. This talk explains how HS2 is assessing its safety and cyber risks in an efficient manner, leveraging products and assessments from the application of the Common Safety Method on Risk Assessment to support cyber assessments based around IEC 62443 risk methodology and associated controls.
