Industrial Control Systems
ICS / SCADA threat hunting
Netcap offers audit records for the following protocols seen in industrial control systems:
- Ethernet/IP
- CIP - Common Industrial Protocol
- Modbus / ModbusTCP
The encoders are enabled by default.
message Modbus {
string Timestamp = 1;
int32 TransactionID = 2; // Identification of a MODBUS Request/Response transaction
int32 ProtocolID = 3; // It is used for intra-system multiplexing
int32 Length = 4; // Number of following bytes (includes 1 byte for UnitIdentifier + Modbus data length
int32 UnitID = 5; // Identification of a remote slave connected on a serial line or on other buses
bytes Payload = 6;
bool Exception = 7;
int32 FunctionCode = 8;
PacketContext Context = 9;
}
message CIP {
string Timestamp = 1;
bool Response = 2; // false if request, true if response
int32 ServiceID = 3; // The service specified for the request
uint32 ClassID = 4; // request only
uint32 InstanceID = 5; // request only
int32 Status = 6; // Response only
repeated uint32 AdditionalStatus = 7; // Response only
bytes Data = 8; // Command data for request, reply data for response
PacketContext Context = 9;
}
message ENIP {
