Intrusion Detection (GIS)
The number of cyber attacks against critical control systems in production facilities and energy supply companies keeps increasing. Substations and their networks represent critical attack vectors and thus their operation and maintenance processes must be included in an effective cybersecurity risk assessment. Effective intrusion detection must monitor and validate in detail threats to IT security, such as illegal encodings and unauthorized control operations, but also communication errors, such as time synchronization problems.
The Intrusion Detection System (IDS) StationGuard monitors Ethernet networks in substations and identifies suspicious behavior, prohibited actions, and malfunctions on the IEC 61850 station or process bus. With this combination of cybersecurity and functional monitoring, not only can new threats and as yet unknown attack scenarios be identified, but different kinds of malfunctions in the substation automation system too.
