CENELEC releases updated TS50701:2023 OT Railway Cyber Security Technical Specification

CENELEC has just released TS50701:2023 with some significant changes. Digital Transit has already incorporated these into their Railway Cybersecurity OT courses.

TS50701 is a technical specification that adapts the cybersecurity industrial control standard IEC62443 to the railway for Operational Technology (OT). In railways, OT Technology includes reliability and safety critical systems such as signalling, SCADA, door systems, brakes, etc.

A critical issue is that IT and OT should be separated and that safety and cybersecurity have complementary goals but must be treated differently – though totally coordinated.
