As technology changes, modern railway signalling systems are becoming more and more reliant on IP Data networks for both their day to day operation as well as for their supportability. For example we now have processor based interlockings at one end of a yard being connected to object controllers at the other end of the yard using IP based data networks. We also have a need to remotely access interlockings and associated systems such as axle counters as well as the data network elements from a central location or a location remote to the organisation to monitor and maintain service of these systems. Whilst all of this takes a level of discipline and rigour to implement, it can also provide a less than secure pathway for an unauthorised person to gain access to the systems if Cyber Security considerations are ignored. This paper will discuss Aurizon’s recognition of the Cyber Security threat to the company as a whole and the signalling system in particular and what has been done to reduce the risks for both.
