We mentioned AppID’s in our introduction of the OPC Security .audit files for use in compliance testing with the Nessus Vulnerability Scanner.

While it is not difficult to find the AppID for your OPC server, we have started a SCADApedia page with the AppID’s to help you out. A lot of this information came from Lluis Mora and the team from Neutralbit. Subscribers can add new AppID’s directly to the SCADApedia page.
