Hello community ...
We are in the need of putting our manufacturing assets behind a firewall to isolate the Production Control Networs for network traffic control as well as for security.
Our current landscape is the information flows from the PLC/Machines to our OPC/Historian and then to our MII servers.
Our possible solution landscape has two options, one is to put a firewall between the machines/plc and the OPC/Historian servers and the second option is to put a firewall between the OPC/Historian server and the MII application server.
Can any body share their experience about what have worked for you and if we decide to put firewall in between OPC.Historian and MII, how is this going to impact our environment and where PCo comes into the picture ?
Thank you in advance.
