Efforts to protect pipelines and other critical systems have been halting despite broad agreement that they're vulnerable to viruses like Stuxnet 2014 the mysterious worm that caused havoc to Iran's nuclear program two years ago.

Stuxnet first made headlines when it burrowed into computers that controlled uranium centrifuges in Iran's renegade nuclear program. Its self-replicating computer code is usually transmitted on flash drives anyone can stick into a computer.
