One argument for the introduction of additional risk is that there is added value to interconnected systems. Look at Electric production and distribution. In the good old days one company produced and distributed across a given area. Now it is a lot more complex. There might be any number of producers transiting a distribution grid and there might even be a choice of paths as to how those electrons get from point A to point B. You have interties across networks, etc. This means more people need access and/or provide more input.
That interconnectedness on the SCADA network (which should NOT be transiting the Internet - only the power grid itself) is exactly how AND why you don't connect the SCADA network to a non-SCADA network. _______________________________________________ firewall-wizards mailing list firewall-wizards () listserv icsalabs com https://listserv.icsalabs.com/mailman/listinfo/firewall-wizards
