Hi, I am seeking help, whether IEC 61850 GOOSE/Sampled values packets be dissected in Suricata?
No, Suricata does not support those protocols. We have an open ticket for MMS which I believe is related, Feature #5675: protocol: MMS SCADA support - Suricata - Open Information Security Foundation.
Please feel free to add other protocols to our ticketing system, but note that we don’t have plan much time from the core team to work on these. It is our hopes that those in the industry who need these protocols contribute them.
