SCADA security

I've just stumbled into the ISA website regarding an ongoing project to develop ANSI/ISA security standards for SCADA (Supervisory Control And Data Aquisition) systems used to control industrial machinery including large chunks of the critical global infrastructure (e.g. power plants, water treatment works, and no doubt the production lines at Rover - oops). In my limited experience, many old-fashioned SCADA systems pre-date modern thinking on information security controls other than availability, perhaps: the reason old SCADA systems remain a problem is that many of them have continued running more or less unchanged for decades.
More availability resources
