Essential Features for Effective IDS/IPS in Electrical Protection

To be effective within electrical protection networks, IDS/IPS solutions require specific features and functionalities:

Deep Packet Inspection (DPI): IDS/IPS should perform Deep Packet Inspection to analyze the content of network traffic, not just the headers. This allows for identifying attacks that exploit specific communication protocols used within electrical protection systems, such as IEC 61850 or DNP3. Traditional port-based security controls that only analyze headers may miss attacks that leverage legitimate ports for malicious purposes.

Protocol Awareness: Understanding the specific communication protocols used by electrical protection devices is crucial for detecting anomalies and suspicious activity. IDS/IPS solutions need to be tailored to the specific protocols used in the electrical grid. This ensures they can recognize valid communication patterns...
