Sure, anytime there's an attack or failure on a SCADA network that wouldn't have occurred had it been air-gapped, it's easy for people to knee-jerk a "SCADA networks should be airgapped" response. But that's not really intelligent commentary unless you carefully consider what risks are associated with air-gapping the network.
Not to mention that it's not the only way for these things to get infected. Getting fixated on air-gapping is unrealistically ignoring the other threats out there. There needs to be a whole lot more security work done on SCADA nets. ... JG -- Joe Greco - sol.net Network Services - Milwaukee, WI - http://www.sol.net "We call it the 'one bite at the apple' rule.
