Hackers Gain "Full Control" of Critical SCADA Systems
mask.of.sanity writes "Researchers have found holes in industrial control systems that they say grant full control of systems running energy, chemical and transportation systems. They also identified more than 150 zero day vulnerabilities of varying degrees of severity affecting the control systems and some 60,000 industrial control system devices exposed to the public internet."
The air gap is not the solution. Proper isolation, firewalling and virus/malware is.
To prevent piracy and sales of used Scada these require internet access to stay activated. We wouldn't want to deprive income now would we
