Cybercriminals have already figured out how to hack into enterprise infrastructure. The critical infrastructure that controls our nation’s supply of water, gas, oil and electricity just might be next. If the critical infrastructure is successfully penetrated, electrical grids could be shut down, water supplies could be turned off, telecommunications channels could be severed, and transportation systems could come to a halt. The two infrastructures — the private/commercial/enterprise infrastructure and the critical/industrial/utility infrastructure — are interconnected in many ways, and security weaknesses within either put both at risk.”]
