Why data needs to be secured
‘Security is needed at all points in our network that process data. Take the smart meter in your home. Your supplier reads out your consumption and transmits it over a data connection. You’ll want this data to be sent to the right place, and without the risk of it being read out by other parties along the way and used for other purposes. This works exactly the same way on a large scale as well. As soon as you allow systems to communicate with the outside world, you must set up the systems in a way that ensures this communication is made securely. The products used in these systems must, of course, support this.
At this moment in time, more and more data is being retrieved from our high-voltage grid. This requires intelligent systems, ones that transport data and store it in a central location through a communication link. Although our high-voltage transmission stations had needed this for some time, now you can see how more and more data is being retrieved from our electricity networks. So, medium-voltage substations and medium or low-voltage areas are increasingly being equipped with automation and protection systems.’
