Substations must be comprehensively protected against cyber attacks. A security strategy that is applied at all levels is ideally suited for this purpose. This includes not only controlling physical access and digital access from outside, but also monitoring and detecting suspicious or unauthorized activity within the network. However, the requirements in a substation are completely different from those for office IT. Suitable systems offer a high degree of security in the long term, while they require little maintenance, and can be easily integrated into the processes involved in maintaining and operating the system.
Since 2010 our experts for protection technology and IEC 61850 have been dealing with the topic of cyber security in substations. It is our goal to share this experience with our customers.
