A security strategy must be applied at all levels to ensure that a substation is comprehensively protected against cyber attacks. Such a security concept includes physical access control, digital access control, and monitoring as well as detecting suspicious or unauthorized activity on the network. This requires systems that offer a high degree of security and flexibility in operation over the long term, while at the same time requiring little maintenance.
StationGuard fulfills exactly this requirement. This IDS (Intrusion Detection System) uses the SCL to create a system model of the substation and then continuously compares each network packet with the live system model. Read in the new Paper of the Month how easy it is to operate StationGuard and how it contributes to increasing the safety level in every phase of the life cycle of your system.
