This guideline aims to contribute to a harmonised, uniform, and consistent approach for managing the safety and security of existing and future Australian and New Zealand railway network assets and systems.

The purpose of this guideline is to provide a reference for rail operators and maintainers on configuration management of firmware and software in the operational rail environment. The guideline aims to assist in developing CM plans and processes to satisfy high-level CM requirements across the product life cycle.

This guideline should assist rail operators and maintainers that are required to implement changes to base firmware, software and configuration of rail assets being introduced into or modified for operational service.
