OPC systems include OPC Servers and OPC Clients. OPC Servers represent the largest risk out of all the components because they typically have direct access to devices and data. While it is fairly trivial to introduce an OPC Client to an unsecured point in a system, it is much more difficult to install and configure an OPC Server to interface with plant resources. Therefore, this webcast will concentrate mostly on securing OPC Servers from unauthorized OPC Client access and restricting authorized OPC Clients to only the functions necessary.
