Rule Category

PROTOCOL-SCADA -- Snort alerted on SCADA protocol activity. SCADA is used in Industrial Control Systems (ICS), programmable logic controllers for large scale systems, such as water treatment facilities. SCADA systems often require no authentication and use generic commands that are hard to screen for. Snort rules look for specific hardware and the traffic protocols they use, as these are often tied to a specific port or URI request.
