Due to numerous cyber attacks on critical infrastructure, including the power grid, some utilities have started to implement sophisticated security measures against digital threats. However, these measures often focus only on traditional IT and the infrastructure around control centers. Substations and their - sometimes unprotected - networks are often neglected attack vectors.
An effective security concept for substations not only includes physical access control and firewalls, but also a monitoring of what is happening within the substation network. With StationGuard, OMICRON has developed a completely new Intrusion Detection System (IDS) to effectively detect cyber attacks and malfunctions in IEC 61850 substations.
